Test Queue
We have set up a test queue on Marylou4 to allow users to develop and test software and submission scripts without having to wait in the main queue as long as it would in the main queue. This queue is subject to the following limitations:
- Jobs cannot use more than 32 processors
- Jobs cannot run for longer than 3 hours
- A limited number of processors (currently 16) will be available in this queue
- Each of these processors is split into two "virtual" processors in the scheduler, meaning that more jobs will get through the queue, but the performance per processor may be reduced; there are a total of 32 virtual processors in the queue
- The resources (processors, time, etc.) used in this test queue will count toward a user or group's soft and hard limits and historical usage information, just as if they were used in the main queue
- There are currently no Infiniband-enabled nodes in the test queue, although this may change in the future
How to use
In order to use the test queue, you will need to do one of the following:
- Pass "-q test" as a parameter to qsub
- Put "#PBS -q test" in your job script
To see the list of jobs currently in the test queue, use the command "showq -w class=test"
