Mellanox HPC-X™ Overview
Mellanox HPC-X™ is a comprehensive software package that includes MPI, SHMEM and UPC communications libraries. HPC-X also includes various acceleration packages to improve both the performance and scalability of applications running on top of these libraries, including MXM (Mellanox Messaging) which accelerates the underlying send/receive (or put/get) messages, and FCA (Fabric Collectives Accelerations) which accelerates the underlying collective operations used by the MPI/PGAS languages. This full-featured, tested and packaged version of HPC software enables MPI, SHMEM and PGAS programming languages to scale to extremely large clusters by improving on memory and latency related efficiencies, and to assure that the communication libraries are fully optimized of the Mellanox interconnect solutions.
Mellanox HPC-X™ takes advantage of the Mellanox hardware based acceleration engines to maximize MP, SHMEM/PGAS and UPC based applications. These acceleration engines are part of the Mellanox adapter (CORE-Direct engine) and switch (SHARP engine) solutions. Mellanox Scalable Hierarchical Aggregation and Reduction Protocol (SHARP™) technology improves upon the performance of MPI operations by offloading collective operations from the CPU to the switch network, and by eliminating the need to send data multiple times between endpoints. This innovative approach decreases the amount of data traversing the network as aggregation nodes are reached, and dramatically reduces the MPI operations time. Implementing collective communication algorithms in the network also has additional benefits, such as freeing up valuable CPU resources for computation rather than using them to process communication.
Mellanox HPC-X™ allow OEM's and System Integrators to meet the needs of their end-users by deploying the latest available software that takes advantage of the features and capabilities available in the most recent hardware and firmware changes,
