Hello, I’am struggling w/ mpirun. I want to test A100 HPL Benchmark. My node doesn’t support infini-band. I have 2 nodes with 8 gpu per node. We are trying to solve this problem in these ways. using mpirun mpirun -np 2 -hostfile ./hosts --allow-run-as-root \ singularity run --nv \ -B …

Hi Rabbins03, Which version of MPI are you using? What version of HPL are you using? The actual error is coming from NVShmem which, per the install guide , only supports the following networks: - InfiniBand/RoCE with a Mellanox adapter (CX-4 or later) - Slingshot-11 (Libfabric CXI provider) - Amaz…

Here’s my version. MPI version is 4.1.2 hpc-benchmarks : 24.0.3.sif My second approach was to install HPC-SDK. Then, I loaded the “nvhpc-openmpi3” module and tried to run the above command, but it got stuck. just in case here my module version. nvhpc → mpi version is 4.1.7a1 nvhpc-hpcx → same…

Hello, May I ask one more? I managed to run my test on 2 nodes, but the performance is significantly poorer compared to a single node. Here’s my command. mpirun -np 16 -hostfile ./hosts \ -x HPL_USE_NVSHMEM=0 \ -x NCCL_P2P_NET_CHUNKSIZE=67108864 -x NCCL_SOCKET_NTHREADS=4 \ singularity…

Hi Rabbins03,

It’s possible to run NVIDIA-HPL without NVSHMEM.
Please set environment variable HPL_USE_NVSHMEM=0 to disable NVSHMEM
