NCSA wiki will be offline Friday, Apr 19, 2024, from 1600 hours until Sun, Apr 21, 2024 in order to upgrade Confluence.
The Delta documentation has moved to a new platform. You will be redirected to the new AMDuProf guide page in https://docs.ncsa.illinois.edu/systems/delta/.
Please bookmark the new URL. Click on the link above if you are not automatically redirected in 7 seconds.
run and collect data
Run a batch job and collect data:
batch script commands
... #SBATCH --constraint=perf # perf,nvperf for gpu nodes cd $SLURM_SUBMIT_DIR export PATH=/sw/external/amd/AMDuProf_Linux_x64_4.0.341/bin:$PATH set -v srun AMDuProfCLI collect --config tbp -o `pwd`/uprof_tbp `pwd`/stream.22gb srun AMDuProfCLI collect --config inst_access -o `pwd`/uprof_inst_access `pwd`/stream.22gb srun AMDuProfCLI collect --config assess -o `pwd`/uprof_assess `pwd`/stream.22gb srun AMDuProfCLI collect --config assess_ext -o `pwd`/uprof_assess_ext `pwd`/stream.22gb
generate report
After collecting data from a batch job, generate reports with the AMDuProfCLI report option.
generate report
[arnoldg@dt-login03 uprof_tbp]$ export PATH=/sw/external/amd/AMDuProf_Linux_x64_4.0.341/bin:$PATH [arnoldg@dt-login03 uprof_tbp]$ AMDuProfCLI report -i AMDuProf-stream-TBP_Dec-19-2022_09-40-27/ /sw/external/amd/AMDuProf_Linux_x64_4.0.341/bin/AMDuProfCLI Translation started ...

visualize and explore report data
You can view the data in AMDuProf on Delta or locally on a copy you install at your desktop system. If you install locally, you may need to replicate some paths or add paths to the binary in order to get full functionality.
Launch AMDuProf ( no CLI suffice for the GUI ), and import the profile session from a completed batch job run with AMDuProfCLI collect ...
The summary view give a high level overview of how time was spent. This is the tbp time-based-profile summary.
The Analyze tab shows hot routines or lines in more detail. The tbp , assess, and inst_access Analyze views follow.
Selecting one of the lines or routines will take you to the Sources view where you can see the assembly used in that portion of code.
The Session Info is under the Summary tab and displays more detail about the profiling session.
