update 10 installation and collect errors on RHEL 6.3

whalajam · ‎08-17-2012

I've downloaded an evaluation of VTune Amplifier XE update 10, and installed it on a stripped down (embedded) 6.3 RHEL - 2.6.32-279.5.1 kernel,Intel Xeon CPU E5645.

- the drivers were built (on a different machine pointing to the kernel version 2.6.32-279.5.1.el6.x86_64)and installed (./insmod-sep3 -r -g root)without errors (dmesg output was inspected),

- occasionally installation fails to install the command line application (amplxe-cl) sometimes (every installation was done after a fresh reboot following the same steps) but installs the GUI app (amplxe-gui) which fails to run due to a missing installed library (libamplxe_libxml_2.7.so). Eventually it installs the command line app (after rebooting).

Installing option that prevents GUI from installing leads to installation failure missing /opt/intel/vtune_amplifier_xe_2011/bin64 (on x86_64 CPU) altogether.

Uninstalling and reinstalling leads to a invalid installation with missing command-line app and bin64 directory.

- running (as root) capture command to attach to a process (created by "nobody") crashes the process, I found a post that recommends to run the command as the same user as the process runs nobody, created a terminal for nobody (it didn't have one) and ran the command, still fails with:

{

amplxe-cl -collect-with runss -follow-child -r /reserved1/runss -duration 20 -target-pid 368

Error: Cannot find running process with the specified ID. Provide valid PID.

-bash-4.1$ ps aux|grep 368

nobody 368 0.0 0.0 446948 13688 ? S

}

- a couple of captures (at system level with webproxy filtering) succeeded but they were for short time (1-2 minutes), I tried to re-capture during a longer interval (first with 10 mins, reduced it gradually back to 1 min) without success, twice I got these (different causes) crash reports:

- one other error was reported at the end of the sampling interval duration as:

{

}

- and many erros as this one, also at the end of the sampling interval:

}

Unfortunatelly, as much as I needed to use the tool, I don't think I can justify purchasing the product unless there is something (installation, kernel module) that I did wrong and I can fix it,

thanks

Good news that you can built drivers on other box (same kernel version) and installed them on the target successfully.

For using the tool on embedded system - in my experience, you can install the tool on other machine first, then copy whole /opt/intel/vtune_amplifier_xe_2011 to the target (insert driver modules on the target, also). amplxe-cl can work, but amplxe-gui can't. You can collect data on target by using command line, and copy the result directory to the Host for analyzing.

Sure, the installation issues were not critical (eventhough would have been correct for the script to check and not to report that amplxe-gui was generated), I managed to install the amplxe-cl (and the modules) and the processing flow is simple enough to follow.

The critical issue is the amplxe-cl errors and crashes that prevented me to get any results, 9 out of 10 times, can you try to help investigate the issues that I reported? (one frequent internal error and the 2 crash reports, one being an assert),

thanks

It seemed that you didn't understand what I said...don't install the tool on the target directly, install it on normal Linux* OS, then copy whole directory (installed tool) to target device.
