How to use "ipmwatch" to measure the data read/write amounts to Optane DCPMM?

[huangwentao]

Hi, I just read from some papers that "ipmwatch" utility can be used to measure the read/write to Optane DCPMM and it is integrated into vtune. I try to google it but find little resources on how to use it. Can anybody show me some guides of how to use it to measure the data read/write to persistent memory? Many thanks for the help.
