Thank you for the reply @ptrblck
I cannot understand the meaning of " 128: number of elements per CTA in M dimension of the C matrix".
CTA means the thread block. The thread block(CTA) has 128 elements because of ‘M’ dimension of the C matrix.
Do you mean ‘128 elements’ as 128 threads in the thread block(CTA)?
So are there total 128*32 threads in the CTA?
Thank you.
