bazdmegHeikoS_mobile: what00:56
HeikoS_mobileNothing really ;)00:57
HeikoS_mobileDon't work too much00:57
bazdmegHeikoS_mobile: my bachelor student defends something today00:57

bazdmegHeikoS_mobile: spectral mixture!00:59
HeikoS_mobileNo please not00:59
HeikoS_mobileThis thing is bazdmeg00:59
bazdmegHeikoS_mobile: 10 hours till his presentation00:59
HeikoS_mobileIe this00:59
HeikoS_mobileOr this?00:59
bazdmegHeikoS_mobile: my student!01:00
HeikoS_mobileSpectral mixture. Man it doesn't work. You gotta tell that to someone01:00
bazdmegit does!01:00
bazdmegyou're just lame!01:00
bazdmegit is better than ARIMA01:00
bazdmegon our data01:00
bazdmegAT LEASY01:01
HeikoS_mobileWe have a pr for it in shogun btw01:01
bazdmegAT LEAST01:01
HeikoS_mobileThis kernel is crap01:01
HeikoS_mobileIt's a crap idea01:01
HeikoS_mobileJust possible because of nips is a fucking farce01:01
HeikoS_mobileAnd all these papers are just stories that people fake01:02
HeikoS_mobileSpectral mixture is one of them01:02
HeikoS_mobileWhat is it?01:02
bazdmegautoregressive integrated moving average01:02
HeikoS_mobileUh sounds fancy01:03
HeikoS_mobileHa well01:04
HeikoS_mobileGood luck to you and your student01:04
HeikoS_mobileI'm sure it'll all be good01:04
bazdmegHeikoS_mobile: uhmm how to show you a pic01:05
bazdmegit is not THAT bad01:06
bazdmeghuman feature engineering like linear model on day of week01:07
bazdmegis not even better01:07
HeikoS_mobileOn toy problems like this it works fine01:08
HeikoS_mobileBecause anything works fine there01:08
HeikoS_mobileLinear model on such data is bazdmeg so of course01:08
bazdmeglinear model on top of day of week01:08
bazdmegwould be like periodic01:09
bazdmegit is quite hard to beat01:09
HeikoS_mobileBut on any real problem, it is impossible to learn the promoters of this thing01:09
bazdmegit is basically - do the same thing forever01:09
bazdmegwell it is real problem01:09
bazdmegI mean it is real data01:09
HeikoS_mobileA periodic kernel plus rational quadratic as a noise model on linear regression does the same01:09
HeikoS_mobileBut these are not interesting problems01:09
HeikoS_mobileInternet scale?01:10
HeikoS_mobileWhat's your N?01:10
bazdmeghaha well it is like visits of website01:10
bazdmegI had to reduce shitload of data to get that01:10
HeikoS_mobileInverting kernel matrix?01:10
bazdmeghaha no the data is small I am joking01:10
bazdmegbut you've never seen that much data01:10
bazdmegI had to reduce ;)01:10
HeikoS_mobileWe do these problems in our assignments here01:10
HeikoS_mobileAll periodic models work well01:11
HeikoS_mobileThing is that the marginal likelihood inherits all the periodicity01:11
HeikoS_mobileSo you immediately get stuck when optimising it01:11
HeikoS_mobileWhich means, you get the solution you put in initially01:12
HeikoS_mobileAnd you can't learn shit01:12
bazdmegHeikoS_mobile: yes that's what he got01:12
bazdmeggpatt was much better01:12
HeikoS_mobileYou know this kernel grammar by the Cambridge guys?01:13
HeikoS_mobileThat's much cooler01:13
HeikoS_mobileLemme check01:13
bazdmegkernels are shit01:13
bazdmegshow me how to run it on my scale01:13
HeikoS_mobileBtw upload your dataset to the automated statistician01:16
HeikoS_mobileIt uses this kernel grammar01:16
HeikoS_mobileGives you a latex with the same plot you showed me01:16
HeikoS_mobileKinda cute01:16
bazdmegyeah I know01:16
HeikoS_mobileAnd no spectral mixture kernel01:16
bazdmegyeah it just01:17
bazdmeglike adds some sine01:17
HeikoS_mobileYeah they have a generative grammar01:17
HeikoS_mobileAnd are careful about parameters01:17
HeikoS_mobileIt also easily get linear plus periodic01:17
HeikoS_mobileMuch more actually01:17
HeikoS_mobilebazdmeg: and for scale, check random features01:18
HeikoS_mobileOr sonney2k svm tricks01:18
HeikoS_mobileHe did that 15 year ago01:18
bazdmegHeikoS_mobile: vowpal wabbit01:18
bazdmegeverybody use that01:18
HeikoS_mobileWhat nips now raves about01:18
HeikoS_mobileWe should update backend01:18
HeikoS_mobileI guess01:18
HeikoS_mobileIt's good01:18
bazdmegit is not01:19
bazdmegbut everything else is bazdmeg01:19
HeikoS_mobileYou can use it with random feature kernels btw01:19
bazdmegit fails badly01:19
bazdmegI mean if it doesn't work01:19
bazdmegit segfault or so01:19
HeikoS_mobileIf something as easy as a linear model fails it is almost always the users fault01:20
bazdmegbut it is very versatile01:20
bazdmegyeah it can segfault on bad input01:20
HeikoS_mobileHappy that shogun got rid of those after all01:20
HeikoS_mobileHad quite a few in the past01:20
HeikoS_mobileI really like your new parameter map01:21
HeikoS_mobileSuch a relief01:21
HeikoS_mobileLook forward to delete Parameter.cpp01:21
bazdmegwell it is quite obvious01:22
bazdmegit can be much more sophisticated01:22
HeikoS_mobileYeah sure01:22
HeikoS_mobileIt's the same idea as is implemented already01:22
HeikoS_mobileJust using c++01:22
HeikoS_mobileRather than c8901:22
bazdmegwell 'any' is a bit fancy01:22
bazdmegit is the best 'any' around there (tm)01:22
HeikoS_mobileYou know how we did it before?01:23
HeikoS_mobileHaha :)01:23
HeikoS_mobileVoid pointer01:23
HeikoS_mobilePlus enum01:23
HeikoS_mobileBut was more powerful01:23
HeikoS_mobileWe had strings if sgvector of sgmatrix01:23
bazdmegit is a bit crazy01:24
HeikoS_mobileLet's delete it next week01:24
HeikoS_mobileAfter Sanuj is merged01:25
bazdmegHeikoS_mobile: you can't even imagine what crazy thing I am now doing01:25
HeikoS_mobileThen imagine it for me01:25
HeikoS_mobileWhat isn't01:25
HeikoS_mobileIs it01:25
bazdmegI just wrote an IPython notebook to create 18 adv campaigns01:25
bazdmegit is like a plumber shit01:26
HeikoS_mobileDon't tell wiking he will bazdmeg you01:26
bazdmegis this I was studying maths for01:26
HeikoS_mobileWell get a better job01:26
HeikoS_mobileDon't sell yourself01:26
bazdmegno I am very good there but I have to do some dirty stuff sometimes01:26
HeikoS_mobileTo me seems like you leave a lot of life energy there01:27
HeikoS_mobileBut can be good of course01:27
HeikoS_mobileJust gotta be careful01:27
HeikoS_mobileAs getting older01:28
bazdmegit is like some cost for doing something meaningful01:28
HeikoS_mobileAnd the corp doesn't give a damn about wasting their wheels, plenty new ones around01:28
HeikoS_mobileWell we better don't discuss this public ;)01:28
HeikoS_mobileYour good there01:28
HeikoS_mobileLong live yandex01:29

HeikoS_mobileI am on phone so hard to type11:24
HeikoS_mobileCan't you change the loop order11:24
Saurabh7HeikoS_mobile, the problem is we ahve a subset11:24
HeikoS_mobileYou do something with all the features or vector 1 then all features of vector 211:25
HeikoS_mobileEtc right?11:25
Saurabh7we here we need all values of a particular feature11:25
HeikoS_mobileBut you do that with all active vectors right?11:25
Saurabh7yes only with active vectors11:26
HeikoS_mobileAnd what do you do with the first feature?11:26
HeikoS_mobileSomething that affects the others?11:26
Saurabh7get all values11:26
Saurabh7sort it11:26
Saurabh7start with first11:26
Saurabh7caluclate a criteria using it11:26
HeikoS_mobileOk, then just sort all components at once11:26
Saurabh7compare for all features11:26
HeikoS_mobileThis way you can go through the vectors one by one11:27
HeikoS_mobileEvery time you touch a vector11:27
HeikoS_mobileAdd all components to sorted set11:27
HeikoS_mobileOne set for each feature11:27
HeikoS_mobileYou see?11:27
HeikoS_mobileRather than doing features one by one11:27
HeikoS_mobileYou process all at once11:27
HeikoS_mobileAnd then this allows you to traverse data column wise11:28
HeikoS_mobileAt least this is my take on it right now11:28
HeikoS_mobileCan you share a link with the code?11:28
Saurabh7but how do I sort the vlules of features11:28
Saurabh7this are rows11:28
Saurabh7while samples are columns11:28
Saurabh7what ?:D11:29

@HeikoSSaurabh7: jo11:36
@HeikoSnow on train wifi11:36
@HeikoScan you send the link again?11:36
@HeikoSSaurabh7: so first of all11:37
@HeikoSthis give a double copy11:38
@HeikoSas mat already is a copy11:38
Saurabh7but this has to be done somewhere11:39
Saurabh7I mean if we want to access rows11:39
Saurabh7but double copy is bad11:39
-!- HeikoS_mobile [] has quit [Remote host closed the connection]11:39
@HeikoSSaurabh7: so the main thing where you need all data is the sorting11:40
Saurabh7yes and then11:40
Saurabh7do some calculation11:41
Saurabh7but yeah the sorting is main11:41
@HeikoSSaurabh7: very bad :)11:41
@HeikoSas doesnt help at all11:41
@HeikoSonly costs11:41
@HeikoSbut lets see this sorting thing11:41
@HeikoSSaurabh7: so my point is11:41
@HeikoSthe outer loop is over features right?11:41
@HeikoSand all loop iterations are independent11:41
@HeikoScould be done in parallel?11:41
@HeikoSthis means11:41
@HeikoSthat you can think of this differently11:42
@HeikoSrather than doing all features one after another11:42
@HeikoSprocess all of them *at once*11:42
@HeikoSso no loop over features outside11:42
@HeikoSbut a loop over vectors11:42
Saurabh7that will be same as transpose11:42
@HeikoSit is more a different way of thinking about the computation that is being done11:43
@HeikoSif all iterations of the loop are independent11:43
@HeikoSand inside one iteration of the loop, you touch all vectors (that particular feature of all vectors)11:43
@HeikoSthen you can instead do11:44
@HeikoSyou iterate over all vectors in the outer loop11:44
@HeikoSand inside one iteration, you "update" the things you do for all components of the vector11:44
Saurabh7right now the update is only getting the feature value11:45
@HeikoSneeds quite a bit of re-factoring the code11:45
@HeikoSbut first it is important to understand the high level idea11:45
@HeikoSof processing all features at once11:45
@HeikoSrather than one after another11:45
Saurabh7so if we loop over all vectors in outer loop11:46
@HeikoSSaurabh7: ok lets simplify a bit11:46
@HeikoSI want to get the idea across11:46
@HeikoSit is independent of RF11:46
@HeikoSthink you have a big matrix11:46
@HeikoSyou divide it into 4 blocks11:46
@HeikoSnow you want to compute the sum of each block11:46
@HeikoSyou get 4 numbers11:46
@HeikoSso far so good11:47
Saurabh7ok :)11:47
@HeikoSnow: you want to permute the matrix, and do the same thign again11:47
@HeikoSgives you 4 more numbers11:47
-!- sanuj [~sanuj@] has quit [Ping timeout: 252 seconds]11:47
@HeikoSnow you want to do this 100s of times11:47
@HeikoSwhich gives you 100s of 4 numbers11:47
@HeikoSget it?11:47
@HeikoSrather than having a loop with 100 iterations11:47
@HeikoSwhere inside, you compute the block wise sums11:47
@HeikoS(which is the naive way)11:48
@HeikoSyou can instead do11:48
@HeikoSyou iterate through the matrix *once*11:48
@HeikoSand then for every element you touch, you figure out (for each permutation of the big matrix) to which of the 4 numbers it is added (for all 100 permutations)11:48
@HeikoSso then you have a single pass over the matrix11:49
@HeikoSand compute block wise sums for 100 permutation11:49
@HeikoSget that?11:49
Saurabh7ok i see11:49
@HeikoSand it is way faster, as you can go through the matrix in memory order, rather than kind of random access from the permutations11:50
@HeikoSso now for the RF11:50
@HeikoSsimilar idea11:50
@HeikoScurrently, you have a loop over all feautres, and you do something to them, every loop iteration is independent11:50
@HeikoSand one loop iteration touches the particular feature of all vectors11:50
@HeikoSinstead, you can iterate through the vectors, and then update (just like the 100x4 terms in the sum before) the part for the corresponding features11:51
@HeikoSthis way, you cann access data in column wise form11:51
@HeikoSjust need to preallocate some things11:51
@HeikoSjust lik ebefore11:51
@HeikoSwe needed to pre-allocate the 4 numbers for each of the 100 permutations11:51
@HeikoSyou can ask lambday if you have more questions on this11:51
@HeikoSit is a tricky one, but might help11:51
@HeikoSa lot in fact11:51
@HeikoSSaurabh7: back in 5 mins11:51
-!- HeikoS [~heiko@] has quit [Quit: Leaving.]11:52
Saurabh7yes I understand the idea11:52
-!- HeikoS [~heiko@] has joined #shogun11:54
-!- mode/#shogun [+o HeikoS] by ChanServ11:54
@HeikoSSaurabh7: so the sorting is the issue11:54
@HeikoSSaurabh7: doing that is hard11:54
@HeikoSas you need to touch all11:54
@HeikoSbut once things are sorted, should be easier11:55
@HeikoSSaurabh7: so I suggest11:55
@HeikoSin the train call11:55
@HeikoSyou create a transposed copy of the features11:55
@HeikoSand then sort each column (that is sortig features)11:55
@HeikoSand then store that somewhere11:56
Saurabh7HeikoS, ok yeah thats one way with transpose11:56
@HeikoSbut this is different to whats currently happening11:56
@HeikoSas you re-sort many times here11:56
@HeikoSI mean, you can just sort *once* at the start11:56
Saurabh7HeikoS, no there is no re sort11:57
@HeikoSand then you can use that sorted matrix everywhere11:57
@HeikoSyou just have to mask it11:57
@HeikoSlet me read11:57
Saurabh7HeikoS, there is no resort here11:57
Saurabh7each row is accesed once11:57
@HeikoSyou only compute the best feature once?11:57
Saurabh7that row is sorted and the index are traveersed11:58
@HeikoSI thought you did that for multiple subsets11:58
@HeikoSin the RF11:58
Saurabh7this thing happens once11:58
Saurabh7on the indices left out11:58
Saurabh7we do it again11:58
@HeikoSyou were talking about changing subsets before?11:59
@HeikoSI mean this is cart tree11:59
@HeikoSbut if you have a RF11:59
@HeikoSdont you do all this multiple times?11:59
Saurabh7ah in rf yes11:59
Saurabh7yes we will do multiple times11:59
@HeikoSso my point is11:59
Saurabh7oh yes taht would be good now isee :)11:59
@HeikoSprecompute the sorting11:59
@HeikoSto-reuse in CARTtree12:00
Saurabh7ok now it makes sense12:00
@HeikoSand then inside cart-tree12:00
@HeikoSassume you have the transposed feature matrix sorted12:00
@HeikoSand then go through that vector wise12:00
Saurabh7yes yes thats a good idea12:00
@HeikoSapplying the trick i mentioned12:00
@HeikoSso this is two steps now12:00
@HeikoS1.) precompute sorted transposed matrix (refactoring the existing code to use that), not changing loop order yet, passing tests12:01
@HeikoS2.) change loop order (f still needed)12:01
@HeikoSSaurabh7: sorting and subsets are somehow redundant right?12:01
@HeikoSif you sort all once at beginning12:01
@HeikoSthen applying a subset doesnt change the fact that things are sorted12:02
Saurabh7oh but we need to sort only form active subsets12:02
@HeikoSas long as subset indices are also sorted12:02
@HeikoSyeah but you can mask that easily12:02
@HeikoSlike imagine your data is12:02
@HeikoSyou sort12:02
Saurabh7ye skip which are niot needed12:02
@HeikoSyou apply subset [0,2,3] and get [1,3,4]12:02
@HeikoSand if you sort the transposed matrix12:03
@HeikoSyou get column wise access for free12:03
@HeikoSBUT I think, you can still do something about your loop12:03
@HeikoSwhich call in CART/RF takes most time? did you profile?12:03
Saurabh7HeikoS, that is here
Saurabh7same one12:04
@HeikoSok then12:05
-!- sanuj [~sanuj@] has joined #shogun12:05
@HeikoSthen the speedup for RF should be x-times this is called12:05
@HeikoSand if you iterate in memory order, your cache misses will drop a lot12:05
@HeikoSso thats a good start12:05
@HeikoSSaurabh7: happy?12:06
Saurabh7HeikoS, yes :)12:06
@wikingmuy bien12:06
Saurabh7HeikoS,  the masking is not straight forward tho12:06
Saurabh7for ex above we want 1,2, 4 not 1,3, 4 as output12:07
@HeikoSwiking: jo12:08
@HeikoSSaurabh7: should not be too hard12:08
-!- sanuj [~sanuj@] has quit [Client Quit]12:08
@HeikoSyou can use a subset stack12:08
@HeikoSor do by hand12:08
@HeikoSsince we dont have subsets on matrices yet12:08
Saurabh7HeikoS, yes need to store indices12:08
@HeikoSSaurabh7: yes12:08
@HeikoSbut keep in mind12:08
@HeikoSyou only need to sort one matrix12:08
@HeikoSand then you can mask that one12:08
@HeikoSwiking: all good?12:09
Saurabh7HeikoS, ok12:09
Saurabh7HeikoS, thanks lot let you know how it goes12:09

@HeikoSOXPHOS: I asked wiking12:29
@HeikoShe will create one from develop12:29
@HeikoSOXPHOS: he will do in 30 mins12:29
@HeikoSOXPHOS: for now, send to develop12:29
@HeikoSand I can discuss there already with you12:30
@HeikoSsince I got a bit of time in train left12:30
@HeikoSOXPHOS: good pace that was :)12:32
@HeikoStrain internet is too slow for http ;)12:33
@HeikoSOXPHOS: wish I could look at it ;)12:36
OXPHOSHeikoS: still loading? xd12:37
OXPHOSwiking: no macro?12:37
@HeikoSOXPHOS: it never started12:38
@HeikoSFrench countryside12:38
@HeikoSlove irc12:38
@HeikoSfor its lo-fi minimal bandwidth12:38
@HeikoSworks everywhere12:38
@wikinghere we go12:38
@wikingI WANT12:39
@wikinghow? :)12:39
OXPHOSit's funny i have to use vpn to log onto irc12:39
@wikingor bazdmeg.github.io12:39
@wikingOXPHOS: .cn?12:39
OXPHOSbut i don't need it anymore once i logged in12:39
@wikingHeikoS: ping pong: "12:39
@wikingdo we need this? i mean wasn't the idea for post GSOC stuff was that we will require c++11? @karlnapf12:39
@wikingwhere is this mister i have irc everywhere?12:40
@HeikoScant see the file still12:40
@HeikoSmaybe you can paste the PR in here ;)12:41
@HeikoSc++11 +112:41
@HeikoSbut wanted to do a release before12:41
@HeikoSwiking: can we do the templating more elgant?12:41
@HeikoSwas sergeys idea12:41
@wikingHeikoS: with linalg stuff in it?12:42
@wikingbazdmeg: can we has :)12:42
@wikingtime to register :)12:42
@wikingHeikoS: so all this stuff that OXPHOS will be doing will only be part post that release no?12:43
bazdmegyes lets register12:43
OXPHOSHeikoS: i'm now doing in init.cpp: #ifdef HAVE_CXX11  if (!sg_linalg)  sg_linalg = std::unique_ptr<SGLinalg>(new shogun::SGLinalg());  #endif12:44
@wikinghow do i create a page bazdmeg ?:)12:44
bazdmeguhmm there is some way12:45
bazdmegyou craete some branch12:45
bazdmegcreate repo12:45
@HeikoSI wonder whether I get all msgs here12:45
@HeikoSwiking: you seem to be scattering ;)12:45
@HeikoSwiking: yeah hopefully, though we can already put it in now12:45
@HeikoSshow c++11 cleaner way and I am all up for it12:45
bazdmegand put index.html with BAZDMEG12:45
@HeikoSI guess this is about doing the backend calls12:45
@HeikoSI dont like register, like this template more12:45
@HeikoSbut i like c++1112:45
@HeikoSso share the wisdom12:45
@HeikoSthis is bazdmeg approved12:45
@HeikoSOXPHOS: I have to look later12:45
@HeikoScant discuss right now12:45
OXPHOSHeikoS: also all linalg classes are guarded by  #ifdef HAVE_CXX11 because I want to stay out of the scope of the raw ptr police ;)12:46
OXPHOSHeikoS: sure! i think wiking cares mainly about the C++11 and the macros12:46
@HeikoSbut he speaks in riddles12:46
@wikingwiking mainly cares about the stupid macros for templates12:47
@wikingthat is sooooo 90s12:47
@wikingsooooooooooooooooooooooooo 90s12:47
@HeikoSI asked 100 times for draft12:47
@HeikoSso this is it, until there is an explcit draft12:47
@wikingit is even more 90s than the friend series12:47
@wikingi never saw there this macro hack12:48
@HeikoScan also copy paste it12:48
@wikingwhich draft had this fucking macro hack?12:48
@wikingyou just said there's a problem12:48
@HeikoSwiking: so I sent it days ago12:48
@wikingwith templated params12:48
@wikingand virtual functions12:48
@wikingthat's all12:48
@HeikoSyesterday the final one12:48
@HeikoSbut idea was ther earlire12:48
@wikingbut i didn't see this macrofucking hack12:48
@HeikoSyeah templated virtual functions12:48
@wikingexplicity fuck12:48
@wikingEXPLICIT bazdmeg12:49
@wikingna mind112:49
OXPHOSokay let's do c++17 magic..if any!12:49
@wikingi'lls end the correction12:49
@HeikoSwiking: show12:49
@wikingno need c++1712:49
@HeikoSshow show show12:49
@wiking11 has it12:49
@HeikoSI dont like it either12:49
@HeikoSso give better way12:49
@wikingsooooooooo fucking funny12:49
@wikingstd::is gives12:49
@wikingAbout Sexually Transmitted Diseases (STDs) - KidsHealth12:49
@wikinganyhow lemme dig it out12:50
bazdmegyes exactly12:50
@HeikoSshould be an easy change12:50
@HeikoSas long as still virtual call of base pointer12:50
@HeikoSah this inet12:52
@HeikoSOXPHOS: I gotta check it later12:52
@wikingOXPHOS: fix your editor12:52
@wikingfor the weird indents12:52
OXPHOSHeikoS: it's okay. going for dinner soon. also a basic question - sg_linalg->set_gpu_backend(new LinalgBackendViennaCL());12:52
OXPHOSwhen will this pointer be released?12:52
@HeikoSOXPHOS: dont know, details for now12:53
@wikingwhen you set a new one12:53
OXPHOSwiking: i tried. i fix with vim everytime afterwards12:53
@wikingOXPHOS: what r u using for editor?12:53
OXPHOSwiking: atom. recommended by many12:53
@wikingor when the SGLinalg's dtor is called12:53
@HeikoSOXPHOS: there is some default backend (eigen3) and then user can change it, thats when the old one goes12:53
@wikingOXPHOS: hahah vim and emacs is recommended by many12:53
bazdmegmy first bachelor student12:53
@wikingatom is not many12:53
@HeikoSbazdmeg: failed? ;:D12:53
bazdmegdefending just now12:53
OXPHOSvim is too geek for me..12:54
bazdmegin the process12:54
@wikingbazdmeg: :)12:54
@wikingOXPHOS: emacs :>12:54
@HeikoSOXPHOS: gedit12:54
OXPHOSlemme try12:54
@wikingyou just need to find an operating system for it :)12:54
bazdmegtotal commander12:54
@wikingOXPHOS: but yeah any time you set_*_backend12:54
@wikingyou have to release the current one12:55
@wikingor when the dtor is called12:55
OXPHOSwas thinking using unique_ptr for gpubackend12:55
@wikingthat reminds meg12:55
OXPHOSso when set..end is called12:55
OXPHOSi'll copy the backend* to unique_ptr12:55
@wikingi mean no matter wtf12:56
@wikingyou gotta have a dtor12:56
@wikingto release12:56
@wikingLinalgBackendBase* cpu_backend;12:56
@wikingLinalgBackendBase* gpu_backend;12:56
OXPHOSyes for now but no for unique_ptr12:57
@wikingi mean those pointers cannot be let there12:57
OXPHOSor just a default one12:57
@wikingi mean if you have those 2 pointers12:57
@wikingyou should release them12:57
OXPHOSyou are right i should12:58
@wikingonce you release SGLinalg12:58
@wikingmemory is your friend12:58
OXPHOSyou sure?12:58
OXPHOSi'll take that ;)12:58
@wikingyeah memory is your friend12:59
@wikingjvm is not12:59
@wikingfuck the gc12:59
@wikingOXPHOS: so for the time being you opted for unaligned memory right?12:59
@wikingand you'll fix that laterz?13:00
OXPHOSwiking: i can fix that once this thing works13:00
@wikingcommented some stuff13:00
@wikingmore than some13:00
