memory traffic from PAPI

[taoyuan]

Hi,
How can I get memory traffic between CPU and memory or between SM and global memory on GPU with PAPI?

The CPU is AMD Phenom(tm) 9950 Quad-Core Processor,GPU is GTX 285.

I run the command papi_avail and I get no PAPI_LST_INS.

Somebody help me!

Thanks A Lot!
