nim-hpx - STE||AR HPX wrapper for Nim

Nim is a system language emphasizing productivity. STE||AR HPX is a high performance computing (HPC)/supercomputing runtime system. nim-hpx provides a STE||AR HPX wrapper for Nim.

nim-hpx wraps STE||AR HPX's asynchronous global address space and parallelism feature set. nim-hpx provides Nim developers tooling to implement HPC applications targeting single node/multicore systems and distributed memory systems (multi-node/multicore systems).

Currently Supports

• futures
• local/remote asynchronous function execution
• local/distributed partitionedSeq, partitionedTable
• parallel foreach, reduce, transform, transformReduce

TODO

• channels
• collective communications
• SPMD support
• coarrays
• asynchronous remote method invocation on classes (components and component actions)
