maxThreadsPerMultiprocessor is always zero #60

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
The attached program reproduces the problem.  A sensible value for the Ocelot 
backends is the same value as maxThreadsPerBlock in the cudaFuncAttributes 
struct (16K IIRC).

$ nvcc ocelot_bug.cu 
$ ./a.out 
Device: NVS 4200M
maxThreadsPerMultiprocessor 1536

$ nvcc ocelot_bug.cu `OcelotConfig -l`
$ ./a.out 
Device: NVS 4200M
maxThreadsPerMultiprocessor 0
Device: Ocelot PTX Emulator
maxThreadsPerMultiprocessor 0
Device: Ocelot Multicore CPU Backend (LLVM-JIT)
maxThreadsPerMultiprocessor 0

This should be fixed in the trunk.

./bug 
Device: Ocelot PTX Emulator
