Dear Bassi users, Bassi is available and running jobs following Wednesday's firmware upgrade. The new firmware uses 128 MB more memory per node. This means that each node has 128 MB less memory available for running your code. The ConsumableMemory resource has been adjusted accordingly. If your LoadLeveler script explicitly sets a value for ConsumableMemory, please note the following change: Total node ConsumableMemory: 27032 MB (26.4 GB) The value you should specify in your LoadLeveler script is 27032/task_per_node. The default value is now 27032 MB/8 = 3379 MB. If you run with 8 tasks_per_node you do not need to explicitly specify ConsumableMemory in your script. Jobs that were queued before Wednesday did not run immediately after the upgrade because they had the wrong default value for ConsumableMemory. We are inserting the correct value for all queued jobs; you do not need to take any action to make them run. Please see the following URL for more on the topic: https://www.nersc.gov/nusers/resources/bassi/running_jobs/memory.php Regards, Richard Gerber
