Hello,
if I exit the running application with ctrl-c, I get the following error each time I want to launch Amplifier:
ERROR - A sampling session is already in progress - Abort current run.
Error in sampling collector. Error code - 57
Error: Sampling session is already in progress.
The only solution is to reboot the system.
How can I get rid of this error to be able to launch other experiments with Amplifier?
Thank you.
Regards,
Oleg
Hi Oleg, Which OS you were running on?
it's RHEL 6.2
First of all, check if your application process really exited after ctrl-c. Then, check if the amplxe-runss process is running. Kill it. If the two above didn't help, unload the sep driver (cd to the 'vtune-install-dir/sepdk/src/' and run rmmod-sep3) and load it again (run the insmod-sep3).
Which version of VTune Amplifier you were using? (amplxe-cl -version)
thanks for your quick response.
about the first two points: yes, I checked that no amplxe process was running.
I'll try the third one next time this problem happens again
$ amplxe-cl -version
Intel VTune Amplifier XE 2011 Update 8 (build 221625) Command Line Tool

Hi,
I am using VTune Ampl. XE 8th Update on SLC5 derieved from RHEL 5 and have the same problem.
Actually I am not allowed to reboot the system, since there are other jobs running.
I was starting a profiling job from command line, which never really started.
Hence I killed the job.
Running the profiling job again returns the ERROR as mentioned here:
ERROR - A sampling session is already in progress - Abort current run.
Error in sampling collector. Error code - 57
Error: Sampling session is already in progress.
Removing the kernel driver is a not ending process, it just never stopped.
I really killed nearly all processes running under my user name, but no effect.
So, is there a fourth suggestion?
Thanx,
Stefan
Update: The machine seems to be dead now. No ssh, no ping.
Using ctrl-C to terminate sampling collection is not recommended.
Use "amplxe-cl -command stop -r r00??" to stop running data collection.
Fourth method is to kill all running processes of VTune Amplifier, anduse rmmod to remove sep & pax drivers manually, you mayuninstall/reinstall the product -if uninstaller doesn't work, you canremove vtune modules (components) manuallythen reinstall the product, check:
# rpm -qa intel-vtune*

Thanks for the fast reply.
amplxe-cl -command stop -r r00??
is unfortunately not helping, it returns:
Fatal error: Cannot detect running collection to deliver command.
Again I killed all processes and returned into the same issue, an unusable sampling driver.
Afterwards I had still the error as mention in the beginning.
I did not remove the kernel modules, since this lead already into a dead host.
Thanx,
Stefan
