I was aware of configurable iteration count in jumbo but personally I think it's against YAGNI principle, but I can add it for consistency. > > In the Makefile, it'd be nice to have this commented-out line for Yellow > Dog Linux (in all of your CUDA patches): > > #CUDA64PATH = /usr/lib64/cuda32 > > I think the mscash2 stuff should get into the next revision of allcuda. Good idea. I'll add path to 32 and 64bit libs in YD. I agree, that was my intention. Lukas
