Re: SPTP Problem when running in Batch

It's not a fixed number, Gord. Whenever QShell needs to run two tasks simultaneously, it creates an additional job.

For example, if you did this:

ls -l | grep ^- | pr | Rfile -wQ mylib/myfile

It has to run multiple jobs, because ls, grep, pr and Rfile all run simultaneously. I don't know exactly which things run in their own jobs and which do not, so I'm not sure if this spawns 3 or 4 jobs? (one to run ls, one to run grep, one to run pr, and one to run Rfile, or does one of them run in the current job?)

Plus, any given program can potentially fork additional jobs. (I doubt ls, grep, pr or Rfile does this, but sftp might...?)

So, I don't know the exact number of jobs needed... honestly, never really thought about it before. I always my QShell in a *NOMAX queue.

Scott, How many jobs in the sftp/qshell jobq would you recommend? How
many jobs does qshell spawn?
