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

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

• futures
• local/remote asynchronous function execution
• local/distributedpartitionedSeq,partitionedTable
• parallelforeach,reduce,transform,transformReduce

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

srun -n4 --mpi=pmi2 ./test_initfin

This library is designed to be run on an HPC system that managesjobs using the following workload managers:Slurm, PBS, etc.

The directory 'tests/' provides several examples regarding how to utilize this library.
