  • Process mapping parallel computing
    Patent number: 9235445
    Abstract: A method of mapping processes to processors in a parallel computing environment where a parallel application is to be run on a cluster of nodes wherein at least one of the nodes has multiple processors sharing a common memory, the method comprising using compiler based communication analysis to map Message Passing Interface processes to processors on the nodes, whereby at least some more heavily communicating processes are mapped to processors within nodes. Other methods, apparatus, and computer readable media are also provided.
    Type: Grant
    Filed: November 28, 2011
    Date of Patent: January 12, 2016

  • Method for computation-communication overlap in MPI applications
    Patent number: 8104029
    Abstract: A computer implemented method is provided for optimizing at the time of compiling a program that employs a message-passing interface (MPI). The method includes: detecting an MPI application source file; identifying a non-blocking communication within the MPI application source file; and overlapping independent computation concurrently with the non-blocking communication. A system is also provided.
