ptxas info - help

Accelerated Computing CUDA CUDA Programming and Performance

Can someone explain what each of the following mean?

ptxas info :
2168 bytes lmem,
140 bytes smem,
1242688 bytes cmem,
99 registers

Thanks

lmem= local memory
smem= shared memory
cmem = constant memory

I keep getting that same number for constant memory.

How is that possible, I thought the limit was 64KB?

Output: ptxas info : 0 bytes lmem, 60 bytes smem, 1242688 bytes cmem, 0 registers

Thanks!

It is a known bug, it will be fixed in the next release.
