Allinea Performance Reports


Allinea Performance Reports characterize the performance of HPC application runs. After executing your application through the tool, a synthetic HTML report is generated automatically, containing information about several metrics along with clear behavior statements and hints to help you improve the efficiency of your runs.

The Allinea Performance Reports is most useful in profiling MPI rograms.

Our license is limited to 64 MPI processes.


Allinea Performance Reports version 6.0 is available

$ ml PerformanceReports/6.0

The module sets up environment variables, required for using the Allinea Performance Reports.


Use the the perf-report wrapper on your (MPI) program.

Instead of running your MPI program the usual way, use the the perf report wrapper:

$ perf-report mpirun ./mympiprog.x

The MPI program will run as usual. The perf-report creates two additional files, in *.txt and *.html format, containing the performance report. Note that demanding MPI codes should be run within the queue system.


In this example, we will be profiling the mympiprog.x MPI program, using Allinea performance reports. Assume that the code is compiled with intel compilers and linked against intel MPI library:

First, we allocate some nodes via the express queue:

$ qsub -q qexp -l select=2:ppn=24:mpiprocs=24:ompthreads=1 -I
    qsub: waiting for job 262197.dm2 to start
    qsub: job 262197.dm2 ready

Then we load the modules and run the program the usual way:

$ ml intel
$ ml PerfReports/6.0
$ mpirun ./mympiprog.x

Now lets profile the code:

$ perf-report mpirun ./mympiprog.x

Performance report files mympiprog_32p*.txt and mympiprog_32p*.html were created. We can see that the code is very efficient on MPI and is CPU bounded.
