| − | On clust (the other Wales group cluster) there are dual-CPU nodes but these are deliberately hidden from the queueing system. The smallest unit |
||
| − | you can get is a single node. This was to avoid the situation we get on |
||
| − | nimbus, a similar machine, where parallel jobs sometimes get assigned one |
||
| − | task on certain nodes, instead of two. This seems to happen despite the |
||
| − | queues being configured to ask for two tasks per node on parallel jobs but it is always possible for users to reset this so I do not know if it is a Maui bug or user error. |

| − | The clearly will not scale to 4-way nodes on the new machine, so |
||
| − | we shall have to allow mixed jobs on nodes. Not sure how to avoid |
||
| − | the users resetting the tasks per node though. A qsub wrapper would be |
||
| − | complex as it would also have to process the job script. |
||
| − | |||
| − | Assuming we do not need variable fairshare for different groups it could be |
