@HeikoSwiking, lisitsyn do director classes work atm?16:28
@HeikoSI have this issue:16:29
@HeikoSeigen3 SVD/eig/chol are single threaded16:29
@HeikoSin anaconda python, there is intel MKL accellerated multi threaded versions16:29
@HeikoSso Id like to overload the method that computes the solve in Python to use the fast one16:29
@HeikoSpossible?16:29
@HeikoSrcurtin: you know about using intel MKL from C++?16:30
@wikingHeikoS, they do16:30
@wikingbut we dont test them systematically16:30
@HeikoSkk16:31
@HeikoSwiking: it is a shame16:31
@HeikoSsince my c++ is so much slower due to this :)16:31

@HeikoSwiking: sorry connection dorp16:42
@wikingnw16:42
@HeikoSat 152816:42
@wikingi'm just trying to keep up16:42
@HeikoShehe16:42
@wikingand not crash :D16:42
@wikingjetlag++16:42
@HeikoSwiking: this mkl thing16:45
rcurtinHeikoS: a little bit16:45
rcurtinbut it's not something I do regularly16:45
@HeikoSshould be easy to link shogun against that16:45
@HeikoSjust provide the so file16:45
rcurtinwhat I remember is that if you want to get MKL it's irritating because you have to fill out some registration form...16:45
@HeikoSyep16:45
@HeikoSbut it is so much faster for matrix solves16:45
rcurtinyeah16:45
rcurtinopenblas also gives a big speedup vs. regular blas or atlas16:45
@HeikoSespecially on intel xeon cpus16:45
rcurtinbut I have not compared openblas vs. mkl16:46
@HeikoShttps://eigen.tuxfamily.org/dox/TopicUsingIntelMKL.html16:48
@HeikoSseems not too hard16:48
rcurtinso, I recently went to a conference on hackathons, and the organizers (who are at CMU) expressed some amount of interest in hosting an mlpack hackathon16:50
rcurtinI said that maybe the mlpack community is a bit small for that, but maybe including other machine learning libraries might be interesting (like shogun)16:51
rcurtinso I have no idea when they will get back in touch to move the idea forward (or if they even will), but if this is a thing that would interest shogun, I can keep you all in the loop16:51
@HeikoSrcurtin: awesome!16:54
@HeikoSlove to join of course16:54
@HeikoSrcurtin: in fact, we will have one in zurich this weekend16:55
rcurtinok, I will keep you in touch... if I don't hear back from them within a month or two I'll poke them and see16:55
rcurtinah, nice :)16:55
@HeikoSrcurtin: btw we signed with numfocus as well, so we hope to organise more of those16:55
@HeikoS(this one is sponsored by ETH)16:55
@HeikoSwe aim to do 2-3 a year from now on16:55
@HeikoSone at gsoc summit16:55
rcurtinwhat does numfocus provide to a sponsored project?16:55
rcurtinlooks like an aggregator for donations I think?16:56
@HeikoSyes that, admin, and exposure I guess16:56
@HeikoScheck the website they do quite a bit of stuff16:57
@HeikoSmight be interesting for you guys as well16:57
rcurtinyeah, I will take a look16:57
rcurtinis their fiscal sponsorship enough to, e.g., bring someone on fulltime?16:58
rcurtinI know that scikit has some full-time people working on it, but I think they are funded not via numfocus, I am not sure16:58
rcurtinwhen I look through the paperwork it looks like a lot of administrative overhead :)17:02

@HeikoSrcurtin: skl is not numfocus17:20
@HeikoSrcurtin: we want to hire ppl, but no idea whether it is feasible17:21
@HeikoSpoint is they would do the admin for us17:21
rcurtinyeah, I see17:24
gideoniteYep, I sure am! HeikoS17:53
@wikingHeikoS, back18:06
@wikingHeikoS, found the power converter18:06
@wikingHeikoS, what's with mkl?18:07
@HeikoSwiking: mkl has multi-threaded matrix solves18:29
@HeikoSwhich eigen3 can use18:29
