"Abstract—Open MPI is an open-source implementation of the\nMPI-3 standard that is developed and maintained by collaborators from academia, industry, and national laboratories.\nOak Ridge National Laboratory (ORNL) and Los Alamos\nNational Laboratory (LANL) are collaborating on porting and\noptimizing Open MPI and related components for use on HPE\nCray EX systems, with a focus on the DOE Frontier and Aurora\nexa-scale systems.\nA key component of this effort involves development of a new\nLinkX Open Fabrics Interface (OFI) provider. In this paper,\nwe describe enhancements to Open MPI, OpenPMIx runtime\ncomponents, and the LinkX OFI provider. Performance results\nare presented for point to point and collective communication\noperations using both the vendor CXI provider and the LinkX\nprovider, including results obtained using GPU accelerators. Recommended deployment options for EX systems will be discussed,\nalong with future work." . "Slingshot 11" . "libfabric" . . "Open MPI for HPE Cray EX Systems" .
