## How to Profile MFC using `omniperf` | ||

* Start an interactive session with the desired number of nodes and total tasks using `salloc -A [account] -J interactive -t 2:00:00 -p batch -N [nnodes] -n [total tasks]` | ||
|
||
* Generate MFC input files by running `./mfc.sh run [path to casefile] -N [nnodes] -n [total tasks] --gpu -t pre_process simulation --case-optimization` | ||
|
||
* Move to the simulation directory using `cd [path to casefile]` | ||
|
||
* `module load` the following modules in the order listed | ||
- rocm/5.5.1 | ||
- cray-python | ||
- omniperf | ||
|
||
* `omniperf profile -n [profile name] -- [path to MFC beginning with /]/build/install/bin/simulation` | ||
|
||
* `omniperf analyze --gui -p [path to casefile]/workloads/[profile name]/mi200` | ||
|
||
* Determine what login node you're on, call it [node name] | ||
|
||
* Open a new terminal window and log into Frontier using `ssh -L8050:localhost:8050 username@[node name].frontier.olcf.ornl.gov` | ||
