Why aren't my batch jobs starting?The RALPP Batch system uses the Maui scheduler to fairly allocate CPU resources between users, groups and Tier 2 (Grid) and Tier 3 (local) use. This means that which job starts next not on how long it has been in the queue but on recent usage of the batch system by the different user groups. So, although you job might head the list of queued jobs reported byqstat that does not mean that it will necessarily start soon.
Luckily Maui provides a few commands to look at the current status which allow you to work out what is going on.
The first showq is fairly straight forward in that it displays the current job queue in priority order:
