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. WebbCOMSOL supports two mutual modes of parallel operation: shared-memory parallel operations and distributed-memory parallel operations, including cluster support. This solution is dedicated to distributed-memory parallel operations. For shared-memory parallel operations, see Solution 1096. COMSOL can distribute computations on …
