19:36 igmar: @imirkin : Bug filed. I'll see what other info I can dig up
22:02 pmoreau: RSpliet: Nice bug! :-D
23:17 HerrSpliet: pmoreau: SPEC is looking into it :-)
23:18 RSpliet: It's funny how many problems I ran into with all these public OpenCL benchmarks just because I used valgrind-mmt to obtain the actual binaries
23:19 RSpliet: I wonder what kind of information should be exposed to devs, what kind of tools they should be given, such that they can find these kind of subtle problems and do proper performance tuning...
