1. A method of data processing 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, the host computer having local memory shared remotely with the accelerators, the accelerators having local memory for the plurality of accelerators shared remotely with the host computer, the method comprising:

  • performing, by the plurality of accelerators, a local reduction operation with the local shared memory for the accelerators;

    writing remotely, by one of the plurality of accelerators to the shared memory local to the host computer, a result of the local reduction operation; and

    reading, by the host computer from shared memory local to the host computer, the result of the local reduction operation.
