Accelerator has two main commands, nc and ncmgr.
To set up your user shell with Accelerator you need to know where the Altair Accelerator software has been installed.
This section summarizes how to submit and run a job.
All log files are normally stored under the subdirectory ./vnc_logs. To remove all obsolete log files in the current working directory, use the nc clean command.
On occasion, jobs that run successfully outside of Accelerator fail when run through Accelerator. When this occurs, mostly likely the setups are not the same: the environment, inputs or other parameters may be different, a misconfiguration or there is a problem with NFS.
When a job is running through a vovtasker, the tasker automatically monitors RAM and CPU utilization of the job, including all of its children.
Reports provide statistical information about all the jobs that are run during a specified time and the usage of the resources that run jobs. The resources include CPU time, licenses, memory and more.
Setting the environment is critical for correct job execution. Accelerator provides two methods to control the execution environment.
Some jobs may require a specific platform or operating system (OS) to run. As Accelerator automatically lists platform/OS as a tasker resources, the task of finding the right host to execute a job is easy: specify the required platform/OS as part of the job resource requirements.
A VovId is a nine-digit string assigned by VOV to each object in the trace.
Each node in the trace has field attributes.
A formatting string is a string that contains field references; it is used to list the elements of a set.
Some VOV procedures and commands accept as input a time specification, which is a string that contains a mixture of digits and the letters s m h d w.
Selection rules are used to create sets and to perform queries.
