- Debug Jobs without Running Accelerator
  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.
- Job Runtime - Monitor and Profile
  When a job is running through a vovtasker, the tasker automatically monitors RAM and CPU utilization of the job, including all of its children.
- Monitor the Workload
- Statistical Information about Resources and Jobs
  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.
- Environment Control
  Setting the environment is critical for correct job execution. Accelerator provides two methods to control the execution environment.
- Job Resources
  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.
