Delivers all the advantages of the Charm++ adaptive runtime system, with the familiar API of MPI
What is CharmMPI?
CharmMPI (formerly known as Adaptive MPI) is an implementation of MPI that delivers the advantages of Charm++’s adaptive runtime system - automated support for virtualization, load balancing and fault tolerance, all with the familiar API of MPI. Users can recompile their existing MPI C, C++, and Fortran applications, and start profiting from improved performance and resilience.
CharmMPI provides dynamic runtime support for pre-existing MPI applications. It can help alleviate scalability bottlenecks that are difficult to address directly in applications, such as static and dynamic load balances and difficult-to-hide communication latencies. CharmMPI also makes it possible to run through node failures and can run on dynamically shrinking and expanding job allocations.
