    574574The parameters for the alternative module are automatically calculated by using an internal conversion model. Module-list is an alternative to `--partition`, which does not apply any conversion model, and submits the job to multiple partitions but with the same configuration. Available conversion models:
    575  - CM to DAM: number of requested nodes / 2, number of tasks per node x2, time limit *1.07
    576  - ESB to CM: same number of nodes, time limit * 10
    577  - DAM to CM: number of nodes * 2, time limit * 10
    578  - DAM to ESB: ntasks per node / 8, number of nodes * 4, time limit / 4
     575 - CM to DAM: number of requested nodes / 2, number of tasks per node x2 (CPU cores ratio)
     576 - ESB to CM: same number of nodes, time limit * 10 (due to GPU vs CPU performance), number of tasks per node / 3 (CPU cores ratio)
     577 - DAM to CM: number of nodes * 2 (due to available memory), time limit * 10 (due to GPU vs CPU performance), number of tasks per node / 2 (CPU cores ratio)
     578 - DAM to ESB: number of nodes * 4 (due to available memory), time limit / 4 (due to using more nodes), number of tasks per node / 6 (CPU cores ratio)
     579
     580It is recommended to specify the number of nodes, the number of tasks per node, and the number of CPUs per task.

    580582Module-list is currently not compatible with other dependencies specified with `--dependency` clause, and also with other partitions specified with `--partition`.
