VTune Aplifier for Ubutntu 11.10

[drMikeT]

I was trying to use VTune Aplifier on an Ubuntu 11.10 box but it could not create the Sampling Driver for the kernel:

$ uname -a
Linux mikexeon 3.0.0-16-generic #28-Ubuntu SMP Fri Jan 27 17:44:39 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

I cd'ed to "/opt/intel/vtune_amplifier_xe_2011/sepdk/src" and tried to "./build-driver" but is says :

root@mikexeon:/opt/intel/vtune_amplifier_xe_2011/sepdk/src# ./build-driver

ERROR: Linux kernels prior to 2.6.x are unsupported ... exiting.

How can I bild teh Sampling Driver for Linux kernel v 3.0.x ?

thanks .... Michael

Anyways, I will try to install VTampl update 7 which is suposed to support Ubuntu 11.10 out of the box ...

A good information page about checking and / or building the sampling driver can be found here. As you already mention, make sure to run the latest update of the product or a version / update of the product best suited for your environment. Support for Ubuntu 11.10 was added in Update 7. Let us know if you have questions, comments, or need assistance.

Hi Rob,

thanks for the pointer. There is good information which unfortunately is scattered around into too many places...

I installed update 7 and it worked out of the box even though the installer claimed it could go only upto Ubuntu 11.04.

BTW, would VTamplU7 install on an older RHEL 5.4 system ? I know that the PAPI for instance requires the perfctr kernel patch.

thanks again
Michael

Michael,

Thank you for the update and good to hear that the Update 7 install went well on Ubuntu 11.04. In regards to Update 7 and RHEL 5.4, it is supported so the installation should work as expected. If you run into problems let us know.

The natural question is if VTamplXE can help with analyzing performance of MPI applications with tasks running on separate nodes as in:

1) use the command line VTampl to launch the MPI code across nodes, such as,

mpirun -np 4 amplxe-cl -collect hotspots -result-dir "./$(hostname)" ./myMPI ag1 arg2 ....

which will save collected data in a separate directory according to the node the command ran.

2) Can now VTampl "combine" performance data collected on these separate directories and consider them as a single application ?

As a matter of fact the above could work on any distributed application (processes talking to each other by message passing on sockets, etc.)

Any suggestions ??

thanks
Michael
