This 2D combination simultaneously reduces the memory consumed by the model, optimizer, and activations. WebbNote that Slurm samples the memory every 30 seconds. This means that if your job is shorter than 30 seconds, it will show that your calculation consumed zero memory which is probably wrong. The sampling rate also means that if your job contains short peaks of high memory consumption, the sampling may completely miss these. dick blick tempera
