When our team used Vtune 2015 Update 2, we could make analysis against mic using the command below.
amplxe-cl -collect=general-exploration -result-dir=./result -target-system=mic-native:1 -- [path to the app]
However, recently we've upgraded to Vtune 2015 Update 4, and now when we execute the command above, it got error "Amplifier cannot detect Intel Xeon Phi coprocessor configuration.". Would you please help us out here?
Also, we are trying to capture cache miss rates on mic to figure out the reason for our program's poor performance. Could you please give us some advice on how to do performance analysis?
My opinion is to check:
1. service mpss status ; you may restart mpss if it did't run
2. ssh mic1 lsmod | grep sep; check if vtune driver is available
If the driver is not loaded, you need to run "sep_micboot_install.sh" under vtune/bin64/k1om. Then restart mpss
3. amplxe-cl -c general-exploration -result-dir result -target-system=mic-native:0 -d 5 ; try data collection without application
Could you also please provide the output from the following commands to help to triage the issue?
>ssh mic1 ls /amplxe
>export | grep MPSS
<vtune_install_dir_on_host>/bin64/sep -version -mic
Thank you, Regards, Dmitry
