In V1R2 of Blue Gene/P (BG/P) there is a new software feature called High Throughput Computing (HTC). This new model of computing for BG/P enables portions of the machine to be allocated for many single-node jobs. Unlike a parallel Message Passing Interface (MPI) job, these HTC jobs or “tasks” are all independent. They start and end independently, and have no MPI communication between the tasks.

Blue Gene/P now offers a hybrid computing model. Support for HTC should provide application developers the option to run exciting new workloads on Blue Gene and allow for extreme scaling of applications.
