OK. That helps.
It does flash a warning though
nbody.kernel.cpp:29:9: warning: '__constant__' macro redefined
#define __constant__ __attribute__((address_space(2)))
/opt/cuda/include/host_defines.h:183:9: note: previous definition is here
#define __constant__ \
1 warning generated.
Another question is
What about extern __shared__ ?
I can see that the error goes away if I replace "extern __shared__ float4
sharedPos" with "__shared__ float4* sharedPos;". Do I have to dynamically
allocate the shared memory by specifying size in kernel Launch? If so, why
doesn't the second use of the same statement in another function cause the
I am using 3.2.
