Is anybody use it to calculate the occupancy of GPU?
We should input our GPU’s parameters firstly in the EXCEL, but I don’t know some parameters.
The GPU data is as follows:
GPU: G80 GTX280
Multiprocessors per GPU 16 30
Threads / Warp 32 32
Warps / Multiprocessor 24 16
Threads / Multiprocessor 768 512
Thread Blocks / Multiprocessor 8 8
Total # of 32-bit registers / Multiprocessor 8192 16384
Shared Memory / Multiprocessor (bytes) 16384 16384
G80 is the sample listed by the author, and my gpu is Geforce GTX 280, So I added my data followed by the G80. But some parameters I can’t be sure(like the data in RED above).Who can help me to check my parameters? Thanks a lot!

Some things are incorrect:
Warps / multiprocessor : 32
Threads / Multiprocessor : 1024
I do not know if Thread Blocks / Multiprocessor has changed, so your safest bet is to leave that indeed to 8
