Hi,
I use amplxe-gui to run tachyon with the guidence of intel vtune tutorial. I receive the following errors, and fail to finalizing results without running the program.

Assertion '(4 ) + (2 +2 +4 +4 + cpu_no*(2 +leaf_no*(2*4 +4*4 ))) == pos' failed. Please contact the developers.
Assertion '(4 ) + (2 +2 +4 +4 + cpu_no*(2 +leaf_no*(2*4 +4*4 ))) == pos' failed. For more information, please visit the technical support forum at https://software.intel.com/sites/support/
I am running withvtune_amplifier_xe_2011_update2.
The application (tachyon) runs as expected outside of Intel VTune Amplifier XE.
The screenshot showing the error is attached

the programs are running underLinux version 2.6.32-5-amd64 (Debian 2.6.32-31), x86_64

Thanks for your help in advance.

Ithinkthat you are working on VTune Amplifier XE 2011 Update 2.

We were aware of such problem from GUI, only happened on latest OS - Is your system Debian* 6? Canthis problembe reproduced on Debian* 5?

My opinion is to use command line, then open result file from GUI. For example,

# amplxe-cl -collect hotspots -- /opt/intel/vtune_amplifier_xe_2011/samples/en/tachyon_find_hotspots /opt/intel/vtune_amplifier_xe_2011/samples/en/dat/balls.dat

Hi Peter,
Thank you for your reply. I use command line to run tachyon, and get the error information again as belows:
boyuan@sitar:~$ amplxe-cl -collect hotspots /curr/boyuan/intel/amplxe/samples/en/tachyon/tachyon_find_hotspots /curr/boyuan/intel/amplxe/samples/en/tachyon/dat/balls.dat

No. I have to report this to development team - probably Debian* 6 is not target OS (not tested) for Update 2.

Canyou use other supported OSs claimed in release notes, or use Debian* 5?

Sorry for inconvenience caused.

Today I installed Update 3 (build #150226) on Debian* 6, it worked wellin command line - I verified.

source /opt/intel/vtune_amplifier_xe_2011/amplxe-vars.sh
cd /opt/intel/vtune_amplifier_xe_2011/samples/en/tachyon
make
amplxe-cl collect hotspots -r /tmp/r0001hs -- ./tachyon_find_hotspots; there is no problem to generate the report.

amplxe-cl -report hotspots -r /tmp/r0001hs; I can find all hot functions.

uname -r ; 2.6.32-5-amd64

Regards, Peter
