VTune empty Report issue with a Gromacs workload

I have encountered an issue with VTune 2021.1-beta06 on DevCloud where it completes profiling a workload with a specific dataset, but when I try to create reports they are empty. If I run the workload with a different, smaller dataset the reports work fine.

-operating system: Ubuntu 18.04.4 LTS and gcc (Ubuntu 7.4.0-1ubuntu1~18.04.1) 7.4.0

Steps to recreate:

1. Download Gromacs: wget http://ftp.gromacs.org/pub/gromacs/gromacs-2020.2.tar.gz

2. Follow the installation steps specified in the following guide (cmake step shown below): http://manual.gromacs.org/2020.2/install-guide/index.html

cmake .. -DGMX_BUILD_OWN_FFTW=ON -DCMAKE_INSTALL_PREFIX= <path to local install dir>    ( e.g. /home/u42144/software/gromacs)

3. Download the dataset then extract: wget https://repository.prace-ri.eu/ueabs/GROMACS/1.2/GROMACS_TestCaseA.tar.gz

4. Run VTune with the workload: vtune -collect hotspots -r v-hotspots -- gmx mdrun -s ion_channel.tpr

5. Create hotspots report: vtune -report hotspots -results-dir v-hotspots

 

example hotspots report output:

Function  CPU Time  CPU Time:Effective Time  CPU Time:Effective Time:Idle  CPU Time:Effective Time:Poor  CPU Time:Effective Time:Ok  CPU Time:Effective Time:Ideal  CPU Time:Effective Time:Over  CPU Time:Spin Time  CPU Time:Spin Time:Imbalance or Serial Spinning  CPU Time:Spin Time:Lock Contention  CPU Time:Spin Time:Other  CPU Time:Overhead Time  CPU Time:Overhead Time:Creation  CPU Time:Overhead Time:Scheduling  CPU Time:Overhead Time:Reduction  CPU Time:Overhead Time:Atomics  CPU Time:Overhead Time:Other  Module  Function (Full)  Source File  Start Address

Hi Lance,

Thanks for reaching out to us.
We tried to follow the steps shared by you in Devcloud and generated the hotspots result. We tried to generate a hotspots report in .txt format using the below command. Could you please try this and check whether you are able to get the report as required.

Command to generate report in .txt format:
vtune -report hotspots -result-dir v-hotspots -report-output <path to save report>/MyReport.txt

Hello,

Thank you for your assistance.

I have it working now. I believe the issue was that I was no longer in Interactive mode on the DevCloud system, so when I tried to create the VTune reports it would not work from the login node.
