| + | === Premise: new job management rules active from 9/10/2022 === | ||
| + | |||
| + | To improve the use of resources, the job management rules have been changed. | ||
| + | |||
| + | * New usage policies based on // fairshare // mechanisms have been implemented \\ | ||
| + | * New queues for job submissions have been defined | ||
| + | - ** sequential ** queue: | ||
| + | * accepts only sequential jobs with a number of tasks not exceeding 1, | ||
| + | * who do not use GP-GPUs, | ||
| + | * for a total number of jobs running on it not exceeding 128 | ||
| + | * and maximum execution time limit of 1 week | ||
| + | - ** parallel ** queue: | ||
| + | * accepts only parallel jobs with task number greater than 1 and less than 1580, | ||
| + | * that use no more 64 GP-GPUs | ||
| + | * and maximum execution time limit of 1 week | ||
| + | - ** gpus ** queue: | ||
| + | * only accepts jobs that use no more than 64 GP-GPUs, | ||
| + | * with task number less than 1580 | ||
| + | * and maximum execution time limit of 1 week | ||
| + | - ** hparallel ** queue: | ||
| + | * accepts only parallel jobs with task number greater than 1580 and less than 3160, | ||
| + | * that make use of at least 64 GP-GPUs | ||
| + | * and maximum execution time limit of 1 day | ||
| + | |||
| + | From 9 October the current queue will be disabled and only those defined here will be active, to be explicitly selected. For example, to subdue a job in the ** parallel ** queue, execute \\ | ||
| + | |||
| + | $ srun -p parallel <MORE OPTIONS> <COMMAND NAME> | ||
| + | |||
| + | If the job does not comply with the rules of the queue used, it will be terminated. | ||
