FastMPJ logo FastMPJ: Fast Message Passing in Java Torusware logo


FastMPJ is an efficient Message-Passing in Java (MPJ) library for high performance support on shared memory and high-speed cluster networks (e.g., InfiniBand). FastMPJ is fully portable, as Java, providing similar performance to native MPI libraries. Development and maintenance of FastMPJ applications is highly productive, while providing low-latency intra-node communications and efficient Remote Direct Memory Access (RDMA) transfers through zero-copy protocols.

FastMPJ enables Java for high performance solutions, especially suitable for the financial sector, particularly in High Frequency Trading (HFT), as well as for High Performance Computing (HPC) and performance critical environments in particular in IT, Energy and Defense/Space. This software is commercialized and supported by Torus Software Solutions.
