Quite often, and without any decernable reason, amplxe-cl hotspot collection hangs and creates no sampling data. Any idea what's causing this.
Some folks in this thread: http://software.intel.com/en-us/forums/topic/277880 seem to have had the same issue, but no solution there was given.
I am running as root. I have tried running with different programs. It even happens when I profile /bin/ls like so:
<root@TPC-G2-06:/d2/tmp/temp> /opt/intel/vtune_amplifier_xe/bin64/amplxe-cl -collect hotspots /bin/ls
Nothing is written to the cwd. The cwd is writeable.
I've taken an strace of the amplxe-cl run. The output of that can be found here: http://pastebin.ca/2436422
If there's any other information that would be helpful, please let me know.
Thanks for your help.
