Vtune is Intel's performance analyszer or profiler. It is capable of analyzing both OpenMP and MPI based codes.
[name@server ~]$ module load vtune
To collect analysis information run:
[name@server ~]$ amplxe-cl -collect <analysis-type> <target_exe> <exe_arguements>
Where <analysis-type> should be replaced by one of the availble analysis, e.g. hotspots, and <target_exe> is the path to the executable you would like to analyze. It is recommended to compile your executable with the "-g" option and to use the same optimization level as normal so as to obtain accurate results.

To create a report run:
[name@server ~]$ amplxe-cl -report <report-type>
where <report-type> is the type of the report to generate, e.g. hotspots.
