Open MPI is a Message Passing Interface (MPI) library project combining technologies and resources from several other projects (FT-MPI, LA-MPI, LAM/MPI, and PACX-MPI).It is used by many TOP500 supercomputers including Roadrunner, which was the world's fastest supercomputer from June 2008 to November 2009, [3] and K computer, the fastest supercomputer from June 2011 to June 2012.
The Message Passing Interface (MPI) is a portable message-passing standard designed to function on parallel computing architectures. [1] The MPI standard defines the syntax and semantics of library routines that are useful to a wide range of users writing portable message-passing programs in C, C++, and Fortran.
MPICH, formerly known as MPICH2, is a freely available, portable implementation of MPI, a standard for message-passing for distributed-memory applications used in parallel computing. MPICH is Free and open source software with some public domain components that were developed by a US governmental organisation, [ 2 ] and is available for most ...
OpenMP (Open Multi-Processing) is an application programming interface (API) that supports multi-platform shared-memory multiprocessing programming in C, C++, and Fortran, [3] on many platforms, instruction-set architectures and operating systems, including Solaris, AIX, FreeBSD, HP-UX, Linux, macOS, and Windows.
MPI implementations typically use TCP/IP and socket connections. [6] MPI is now a widely available communications model that enables parallel programs to be written in languages such as C , Fortran, Python , etc. [ 8 ] The MPI specification has been implemented in systems such as MPICH and Open MPI .
Open MPI represents a community-driven, next generation implementation of a Message Passing Interface (MPI) fundamentally designed upon a component architecture to make an extremely powerful platform for high-performance computing. LAM/MPI was officially retired in March 2015. [1] LAM (Local Area Multicomputer) is an MPI programming environment ...
OpenSHMEM is a standard effort by SGI and Open Source Software Solutions, Inc. University of Houston: Reference OpenSHMEM [4] [9] Mellanox ScalableSHMEM [9] Portals-SHMEM (on top of Portals interface) University of Florida: Gator SHMEM [9] Open MPI includes an implementation of OpenSHMEM [11] Adapteva Epiphany Coprocessor [12]
Microsoft Message Passing Interface (MS MPI) [1] is an implementation of the MPI-2 specification by Microsoft for use in Windows HPC Server 2008 to interconnect and communicate (via messages) between High performance computing nodes. It is mostly compatible with the MPICH2 reference implementation, with some exceptions for job launch and ...
