Some key functionality in Accelerator Plus is provided by external daemons.
This section describes the theory of the operation of Accelerator Plus on Accelerator and how to address problems should they occur.
In order to successfully run jobs under Accelerator Plus, submitting to Accelerator, some configuration must be done up front.
Direct Drive provides a method to reduce latency of job start times and improved scaling as more base queues are added.
Like all vovservers, access to Accelerator Plus can be controlled by editing the security file wx.swd/security.tcl.
In Accelerator Plus, each job goes through a number of states until completion.
