5.1.1. Job Configuration

The parameters on this tab allow you control over the how a job is run.

Parameter Name

Description

Minimum Number of Processes

Minimum number of logical processors (as seen by OS) to allocate for the job (0 = Use all available, -1 = Use all but one, etc.). Visible only if a remote Queue (see the following) is not specified.

Maximum Number of Processes

Maximum number of logical processors (as seen by OS) to allocate for the job (0 = Use all available, -1 = Use all but one, etc.) The default is 0 to permit fullest utilization of available resources. Prior to version 12 of Analyst the default was 1, and it is recommended to set this value to 0 when migrating older projects to the current version.

Number of Threads Per Process

Number of threads to use per process. The total number of threads is given by this value times the number of processes in use for a particular job. If a simulation has idle processes, the unused threads will be redistributed to the active processes for optimal efficiency.

Number of Remote Nodes

Number of nodes to be requested (up to the total number of nodes available) from the remote cluster scheduling system for the job. Must be non-negative (0 = Use all available). Visible only if a remote Queue (see the following) is specified.

Maximum Memory Load Fraction

If the projected memory consumption for the next AMR step exceeds this fraction of the total available system memory, the AMR sequence is stopped. Note that this is only an estimate.

Queue

Name of the job queue on which to run the job. "Any" implies use first compatible and available queue.

Allow Concurrent Execution

If false, the job scheduler will run only one job at a time regardless of licensing and the number of processes/threads specified in the properties. This is an important parameter if you want to queue several large serial simulations instead of having several run at the same time. Visible only if a remote Queue (see above) is not specified.
