- Please note that using the wildcard in the name of the parallel environment for a parallel job at Placentia, like so
ompi*, may result in placing your job on the Green ACENET resources that are not quipped with InfiniBand. In order to avoid this, do not use the trailing wildcard character, e.g.
-pe ompi 16. This arrangement is independent of the subordinate queue, and only happens when the Green ACENET resources get manually reassigned to general productions queues.
The following resources are part of our Green ACENET program and are priority access for the groups funding the acquisitions. If you are interested in a similar arrangement, please contact support. Green nodes are available to the general community via the subordinate queue.
