Hi,
I run a kernel on Fermi,
solver<<<grid1,block1>>>( rinA, Xn, zinB, rinG, zinG, R, Wn, t_R, tempR, temprinG, EN, sortEN );
where, block1 is 8 and grid1 is 64.
with -arch=sm_20 -Xptxas -v, I got the following info:
ptxas info : Compiling entry function ‘Z11solverPfS_S_S_S_S_S_S_S_S_S_S’ for ‘sm_20’
ptxas info : Function properties for Z11solverPfS_S_S_S_S_S_S_S_S_S_S
8 bytes stack frame, 0 bytes spill stores, 0 bytes spill loads
ptxas info : Used 40 registers, 128 bytes cmem[0], 128 bytes cmem[14], 56 bytes cmem[16]
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
- What is the meaning of:
8 bytes stack frame, 0 bytes spill stores, 0 bytes spill loads
ptxas info : Used 40 registers, 128 bytes cmem[0], 128 bytes cmem[14], 56 bytes cmem[16]
- What is cmem[n]?
Thank you.
