@HeikoSwiking: yeah!!!!12:57
@HeikoSmeta examples now work with python312:57
@HeikoSwiking: (if python-ply is installed)12:57
sanujHeikoS: cool12:57
@HeikoSwiking: the check is not working yet though ....12:57
sanujHeikoS: I'll work on adding eigen3 llt in krr12:59
sanujHeikoS: shall i add it in linalg and then use that in krr?12:59
@HeikoSsanuj: use eigen3 in krr for now13:00
@HeikoSand then add it to linalg anyways ... for the GPs13:00
sanujokay13:00
@HeikoSbut KRR should continue to work without linalg for compat. reasons13:00
@HeikoSwe dont want to break things and it is no big deal to change later13:00
sanujunderstood13:00
@HeikoSsanuj: but GP framework is based on linalg anyways, so we can use the LLT from linalg13:00
sanujHeikoS: okay13:01
@HeikoSas it is already unavailable without c++11 anyways13:01
sanujHeikoS: and i'll write my next cookbook page on SVMs13:01
sanuji'll start writing my gsoc proposals this weekend13:01

@HeikoSlambday: so as I was saying, how shall the linalg functione be called?17:39
@HeikoSbecause spcifying the backend kind of defeats the purpose of being backend independent17:39
@lambdayHeikoS: if eigen3 is default, to call eigen3 version you just do linalg::foo(...)17:39
@HeikoSlambday: ok17:40
@lambdaybut to call viennacl, you specify the backend17:40
@lambdayor native, for that fact17:40
@HeikoSlambday: since we dont want to automatically replace all calls via viennacl17:40
@HeikoSlambday: and this is why you are saying we dont need global backends17:40
@HeikoSand no vianna cl build?17:40
@lambdayHeikoS: yeah I really don't think it is of any practical use17:41
@HeikoSlambday: ok17:41
@HeikoSlambday: what about this:17:41
@lambdaythere is no use-case when we'd want all our backends to be gpu17:41
@HeikoSah no17:41
@HeikoSactually, it is fine17:41
@HeikoSputting things on the GPU is always an explicit decision17:41
@HeikoSah yes, but here is a case I was thinking of17:41
@HeikoSsay we implemented an algorithm using viennacl backend17:42
@lambdayHeikoS: the other way it can be handled is to just overload the methods..17:42
@HeikoSno 2 cases might be a problem:17:42
@lambdaylinalg(SGType) calls eigen backend, linalg(GPUType) calls viennacl backend17:42
@HeikoS1.) we find a better library for doing gpu  backends ... then we have to change the algorithms, which is against the design pattern on linalg. so maybe rather than viennacl, we should call it GPU backend or so17:43
@HeikoS2.) what a user doesnt have a GPU17:43
@HeikoSthen there needs to be the fall back option of running the same code on shared memory with the CPU17:43
@HeikoSagain without changing the algorithm code17:43
@lambdayHeikoS: viennacl+opencl can work on cpu as well17:43
@HeikoSok, but do you see my point?17:44
@HeikoSwe are kind of mixing hardware backends with software backends17:44
@HeikoSwhile hardware backend is clear when algo is written, software backend should be possible to change without touching the algorithms17:44
@lambdayHeikoS: yeah I see what you mean..17:45
@lambdayHeikoS: the dependency kind of have to be like eigen3... for all cpu computation we rely on eigen, for all gpu backends we rely on viennacl17:46
@lambdaycause, the other better backend may not be as flexible as viennacl and may simply fail when no GPU is there17:47
@lambdayviennacl can manage working on cpu as well17:47
@HeikoSI would offer a general (lib free) GPU backend that17:48
@HeikoS-uses viennaCL on GPU by default17:48
@HeikoS-uses viennaCL on CPU if no GPU is present17:48
@HeikoS-uses CPU backend if none is available17:48
@HeikoSand the general CPU backend17:49
@HeikoS-defaults with eigen317:49
@HeikoS-we might add other libs to support its operations17:49
@wikingasdf17:50
@wikingFUCKING APPLE17:50
@wiking:)17:50
@wikingwhats the problem with viennacl as gpu backend?17:51
@HeikoSwiking: just talked to lambday18:17
@HeikoSwiking: we want to refactor linalg a but18:17
@HeikoSbit18:17
@HeikoSwiking: the idea is to separate backend abstraction for library and hardware18:17
@HeikoSwiking: in algorithms, one only chooses which hardware backend is used, i.e. cpu or gpu18:18
@HeikoSwiking: and for each of those, cmake decides for a particular library at compile time18:18
@HeikoScurrently it is all a bit mixed up18:18
@HeikoSwe will do a one file prototype to illustrate the ideas18:18
@HeikoSwith all the fallback options18:18
@HeikoSand then when compiling, based on what libraries and hardware is available, all those things are populated18:19
@HeikoSbut then algorithm implementation in shogun only specifies cpu or gpu, not library18:19
@HeikoSthis also means: no global viennacl backend anymore18:19
@HeikoSbut you will see the prototype18:19
@lambdayI'll try to cook something up by the end of this week for the prototype and share with you guys18:20
