GPU cuda autocompilation in IMP
by Barak Raveh 30 Apr '15

30 Apr '15

I added an apparently operational cuda auto-build (any .cu file placed in src or src/internal should work). It seems to work fine but let me know if it causes havoc. Important note - the cuda build system hates the IMP namespace, specifically. Perhaps its some internal cuda macro. It means we cannot include <modulename>_config.h in any cuda files, for now, and need to add a bypass if we need to access an IMP method or object from cuda code. Barak

profiling imp code to boost your speed
by Barak Raveh 17 Apr '15

Hi all, Following Tuesday's discussion on slowness of IMP on some instances - all should be reminded of the powerful --cpu_profile IMP flag. Just add it to your command line, and IMP will generate a profiling file that you can view with google profiler as a tree: pprof --gv <your-binary-file> <the-profile-info-file-generated-by-cpu_profile-flag> it's almost certain you can at least double the performance of your app with a few simple steps. Likely more. Try to apply it to a long process (>60 seconds) so you will profile the interesting parts of your process, and not the overhead of loading files, etc. -- Barak
