In many cases, it is useful to submit a huge (>100) number of computational jobs into the PBS queue system. A huge number of (small) jobs is one of the most effective ways to execute embarrassingly parallel calculations, achieving the best runtime, throughput, and computer utilization. In many cases, it is useful to submit a huge (>100) number of computational jobs into the PBS queue system. A huge number of (small) jobs is one of the most effective ways to execute embarrassingly parallel calculations, achieving the best runtime, throughput, and computer utilization.
However, executing a huge number of jobs via the PBS queue may strain the system. This strain may result in slow response to commands, inefficient scheduling, and overall degradation of performance and user experience for all users. For this reason, the number of jobs is **limited to 100 per user, 1000 per job array**. However, executing a huge number of jobs via the PBS queue may strain the system. This strain may result in slow response to commands, inefficient scheduling, and overall degradation of performance and user experience for all users. For this reason, the number of jobs is **limited to 100 jobs per user, 4000 jobs and subjobs per user, 1500 subjobs per job array**.
