amplxe: Error: Permission error mapping pages

Hello,

I'm a new user of Vtune. I installed as root vtune_amplifier_xe_2015 on a suse 11 linux node.

I try to collect informations about hotspots for an MPI application and I get the following error :

mpirun -np 20 amplxe-cl -r .  -collect advanced-hotspots -- ./mycodeamplxe: Error: Permission error mapping pages.
Consider increasing /proc/sys/kernel/perf_event_mlock_kb,
or try again with a smaller value of -m/--mmap_pages.
(current value: -1)
/opt/intel/vtune_amplifier_xe_2015.1.0.367959/bin64/amplxe-perf-sync: Terminated

<!--break-->

The whole output is the folowing :

mpirun -np 20 amplxe-cl -r .  -collect advanced-hotspots -- ./mycode
amplxe: The analyzed process has a rank of 8. This rank will be added to the result path/name.
(twenty times)

amplxe: Collection started. To stop the collection, either press CTRL-C or enter from another console window: amplxe-cl -r /absolute/path/run.7 -command stop.

zero-sized file (/absolute/path/run.4/data.0/temp.sync.perf), nothing to do!

I check the perf_event_mlock_kb :

more /proc/sys/kernel/perf_event_mlock_kb
516

which is what I can expect. But I don't know, and don't find what to do with the error concerning the mapping pages.

Thank you for your help.
