First, there are two performance counters in GPU, which are “ L2 Compression Success Rate” and “L2 Compression Ratio”. Could someone clarify the differences between these two?
Secondly, I profiled cudaCompressibleMemory, and from the print outs it appears that there is compression and performance improvement.
but in reality, I did not get any relevant data through these two metrics in the NCU report.
Are these two metrics not implemented in NCU?
