rekadoI'm maintaining the shogun package for GNU Guix.  Since upgrading Octave from 3.8.x to 4.x the Octave bindings of Shogun can no longer be built.10:12
rekadois this a known issue?  Should I keep Octave at 3.8.x?10:12
@wikingey11:58
@wikingSaurabh7: ohere?11:58
@wikingrekado: do you have an error msg for me?11:59
@wikingmmm first time i hear about guix11:59
@wikingseems like a cool project11:59

Saurabh7hey wiking12:38
@wikinghello12:47
@wikingwazzap12:47
Saurabh7wiking: I was updating the liblinear code with openmp version12:48
Saurabh7but our dot product in dotfeatures already has pthread thing12:48
@wikingah the omp version from the authors?12:48
Saurabh7yes12:48
@wikingand how is it?12:49
Saurabh7wiking: no, I mean omp is used in this updated code, but dot prodcuts use pthread12:50
Saurabh7which was not gving less speedup I think12:51
Saurabh7sry lol12:51
Saurabh7which was giving less speedup12:51
Saurabh7wiking: would it make sense to add omp based odt products too ?12:51

Saurabh7I see cool , I have added similar method there based on omp12:54
Saurabh7could be replaced as well12:54
Saurabh7wiking: btw this is the right way of updating the liblinear code right ?12:55
Saurabh7I am just taking the whatever omp things they have added and putting in ours12:56
Saurabh7heiko was questioning something in the comments12:56
@wikingah well12:57
@wikingwould be better12:57
@wikingthat we could just add it as a module12:57
@wiking:)12:57
@wikingdunno how sanuj is proceeding with the modular part12:57
Saurabh7yes12:58
@wikingbut yeah currently when i did an update13:00
@wikingi copied the file over13:00
@wikingand then changed some definitions13:00
@wikingbut it's not really optimal solution :P13:01
Saurabh7I see , so similar to what I am trying to do ?13:03
Saurabh7wiking: should I continue it this way then13:04
Saurabh7needs a few more similar changes13:05
@wikingyep13:05
Saurabh7cool thnks13:07
