Enter the TACC Parametric Launcher, which lets you submit a batch of commands all at once, to be processed on a dedicated set of compute nodes. Why not just submit a bunch of small jobs? Large, shared systems like Lonestar have limits on the number of jobs you can submit at once (50), and each job will have to wait independently in the queue. Due to the FairShare policy implemented on many large shared systems, this means your jobs will wait slightly longer each time a new one enters the queue and starts running. Even without FairShare, each job will have a finite, non-zero waiting time. The idea behind the Launcher is to consolidate all that computing into big request. You may wait a bit to get access to a larger number of nodes, but all in all, your computing will complete MUCH more quickly and efficiently.
