vTune axmple-cl memory-access hangs on

Hi.

I use the vTune amplxe-cl -collect memory-access command to collect data.The vTune version is vtune_amplifier_xe_2016_update4.tar.gz , my linux version is CentOS7 , and my CPU is Core i3.When I use the action option with memory-access , bandwidth , and  cpugpu-concurrency ,the command will hangs on there. When I use other action option like hotspots, advance-hotspots can not hang on and run normally. My command like these :

amplxe-cl -collect memory-access -target-duration-type medium -target-pid 9692

amplxe-cl -collect memory-access -target-duration-type medium -target-pid 9692 -duration 10

amplxe-cl -collect memory-access -knob analyze-mem-objects=true -knob dram-bandwidth-limits=true  -target-pid 20753

All these commands will hang on when using. Can someone help me?

Thanks.
