XcalableMP (XMP) is a parallel programming language designed for high-performance computing, extending C and Fortran with directives to simplify parallelization across distributed memory systems. It enables efficient data distribution, task parallelism, and communication among processes to optimize performance on large-scale supercomputers.
About Xcalablemp
XcalableMP was developed in the early 2010s by researchers and engineers aiming to simplify parallel programming for high-performance computing. It emerged from a need to efficiently harness the power of large-scale distributed memory systems, providing a straightforward way to manage data distribution and parallel tasks. The language built on existing paradigms from C and Fortran, incorporating directives to streamline parallelization efforts.
Strengths of XcalableMP include its ease of use for parallelizing existing C and Fortran code, efficient data distribution, and scalability on large systems. Weaknesses involve limited adoption compared to more established languages and potential complexity in debugging parallel applications. Competitors include MPI (Message Passing Interface), OpenMP, and UPC (Unified Parallel C).
