Direct injection of data to be transferred in a hybrid computing environment
First Claim
1. A method of direct injection of data to be transferred in a hybrid computing environment, the hybrid computing environment comprising a host computer having a host computer architecture, a plurality of accelerators having an accelerator architecture, the accelerator architecture optimized, with respect to the host computer architecture, for speed of execution of a particular class of computing functions, the host computer and the accelerators adapted to one another for data communications by a system level message passing module, each accelerator further comprising a Power Processing Element (‘
- PPE’
) and a plurality of Synergistic Processing Elements (‘
SPEs’
), the method comprising;
reserving, by each SPE of an accelerator, a slot in a shared memory region accessible by the host computer;
loading, by each SPE from local memory of the accelerator into local memory of the SPE, a portion of data to be transferred to the host computer;
executing, by each SPE in parallel, a data processing operation on the portion of the data loaded in local memory of each SPE; and
writing, by each SPE, the processed data to the SPE'"'"'s reserved slot in the shared memory region accessible by the host computer.

Abstract
Direct injection of a data to be transferred in a hybrid computing environment that includes a host computer and a plurality of accelerators, the host computer and the accelerators adapted to one another for data communications by a system level message passing module. Each accelerator includes a Power Processing Element (‘PPE’) and a plurality of Synergistic Processing Elements (‘SPEs’). Direct injection includes reserving, by each SPE, a slot in a shared memory region accessible by the host computer; loading, by each SPE into local memory of the SPE, a portion of data to be transferred to the host computer; executing, by each SPE in parallel, a data processing operation on the portion of the data loaded in local memory of each SPE; and writing, by each SPE, the processed data to the SPE'"'"'s reserved slot in the shared memory region accessible by the host computer.
