| | ====== Working on GPU nodes Interactively ====== |
| | |
| | **Interactive mode** |
| | |
| | <code> |
| | 1. VSC-5 > salloc -N 1 -p zen2_0256_a40x2 --qos zen2_0256_a40x2 |
| | |
| | 2. VSC-5 > squeue -u $USER |
| | |
| | 3. VSC-5 > srun -n 1 hostname (...while still on the login node !) |
| | |
| | 4. VSC-5 > ssh n3066-012 (...or whatever else node had been assigned) |
| | |
| | 5. VSC-5 > module load cuda/9.1.85 |
| | cd ~/examples/09_special_hardware/gpu_gtx1080/matrixMul |
| | nvcc ./matrixMul.cu |
| | ./a.out |
| | |
| | cd ~/examples/09_special_hardware/gpu_gtx1080/matrixMulCUBLAS |
| | nvcc matrixMulCUBLAS.cu -lcublas |
| | ./a.out |
| | |
| | 6. VSC-5 > nvidia-smi |
| | |
| | 7. VSC-5 > /opt/sw/x86_64/glibc-2.17/ivybridge-ep/cuda/9.1.85/NVIDIA_CUDA-9.1_Samples/1_Utilities/deviceQuery/deviceQuery |
| | </code> |

| | ====== Working on GPU using SLURM ====== |
| | |
| | **SLURM submission** gpu_test.scrpt |
| | |
| | <code bash> |
| | #!/bin/bash |
| | # |
| | # usage: sbatch ./gpu_test.scrpt |
| | # |
| | #SBATCH -J A40 |
| | #SBATCH -N 1 |
| | #SBATCH --partition zen2_0256_a40x2 |
| | #SBATCH --qos zen2_0256_a40x2 |
| | |
| | module purge |
| | module load cuda/9.1.85 |
| | |
| | nvidia-smi |
| | /opt/sw/x86_64/glibc-2.17/ivybridge-ep/cuda/9.1.85/NVIDIA_CUDA-9.1_Samples/1_Utilities/deviceQuery/deviceQuery |
