Dear Vtune experts,
I am using vtune in command line mode to profile the time taken by each function in my code.
amplxe-cl -collect knc-general-exploration --target-duration-type=veryshort --search-dir all:rp=./ -- ssh mic0 -t "ulimit -s unlimited; /tmp/myname/nekbone"
I can see the output of my application (name: nekbone) but vtune ends with the following message:
amplxe: Error: Failed to create a tb6 file because 0 samples were collected.
amplxe: Collection stopped.
amplxe: Using result path `/home/pbalapra/Projects/nekbone-2.3.4/test/example1/r002ge'
amplxe: Executing actions 50 % done
amplxe: Error: Error 0x4000001e (Cannot load raw collector data)
Soft and hardware info:
amplxe-cl --version
