Complete HPL (Linpack) keyboard shortcuts and commands reference — 11 shortcuts across 2 categories. Quick reference cheat sheet for Windows & Mac.
| Shortcut | Action | Description |
|---|---|---|
| mpirun -np 16 ./xhpl | Run HPL benchmark | Launch the Linpack solver across 16 MPI ranks, reading HPL.dat for configuration. |
| mpirun -np 8 --map-by l3cache ./xhpl | Cache-aware mapping | Bind ranks to L3 cache domains for better memory locality on multi-socket nodes. |
| mpirun -np 8 --bind-to core ./xhpl | Core binding | Pin each MPI rank to a dedicated CPU core for consistent performance. |
| srun -N 4 --ntasks-per-node=8 ./xhpl | Run via Slurm | Launch the HPL benchmark through a Slurm job allocation. |
| mpiexec -f machinefile -n 32 ./xhpl | Run with machinefile | Launch across the nodes listed in an MPI machinefile. |
| ldd xhpl | Check library links | Verify the compiled binary can find its BLAS and MPI shared libraries before running. |
| Shortcut | Action | Description |
|---|---|---|
| vi HPL.dat | Edit configuration | Edit the HPL.dat input file controlling problem size (N), block size (NB), and process grid (P x Q). |
| ibcheckerrors | Check IB fabric | Confirm the InfiniBand fabric reported no errors during the benchmark run. |
| top | Monitor CPU usage | Confirm all MPI processes are near 100% CPU utilization during the run. |
| grep Gflops HPL.out | Read result | Extract the achieved GFLOPS figure from the HPL output log. |
| singularity run hpc-benchmarks.sif ./hpl.sh --dat file | NVIDIA container run | Run NVIDIA's optimized HPL container build, common on GPU clusters via NGC. |
