Job Dependencies

One can indicate a dependency between two or more jobs by using the -W x=depend:dependency-type:jobid flag for the msub commando. For example to tell moab that job2.sh can only run after job1.sh successfully finishes, one can use:

$ msub job1.sh
12345

$ msub -W x=depend:afterok:12345 job2.sh
12346

This will queue job1.sh with a jobid of 12345, queue job2.sh with jobid 12346 and indicate moab that job2.sh has to wait until job1.sh has finished.

High Performance Computing @ FSU

Computational resources are a critical part of scientific research and engineering programs and play an increasingly important role in preparing students for careers in both commercial and academics fields. Recent advances in data acquisition, algorithm development, and computer hardware have made High Performance Computing (HPC) fundamentally necessary to remain competitive. FSU has long recognized the importance of local HPC resources for research and education. In 2002 FSU gained the distinct honor of having the largest university-owned computer facility worldwide and 34th largest among all facilities. Since its inception this facility has enabled research programs spanning such disciplines as biology, engineering, physics, meteorology, mathematics, oceanography, and more (see our research page for details).

The FSU HPC mission is to:

  • Support multidisciplinary research
  • Provide a general access computing platform
  • Encourage cost sharing by departments with dedicated computing needs
  • Provide a broad base of support and training opportunities
