Why?

Nim-HPX provides Nim users the parallel and distributed computing functionality found in STE||AR HPX. Nim developers using this library get the following tools: asynchronous function support (local/remote), parallel algorithms, distributed vectors and coarray support, block-level SPMD (single-program many data) support, futures/promises, await/dataflow, and asynchronous method execution (local/remote).

How?

Nim-HPX requires the following dependencies:

• pkg-config
• cmake
• hwloc
• tcmalloc
• papi
• Boost
• APEX
• STE||AR HPX

It's recommended that everything but APEX and STE||AR HPX be installed using your GNU/Linux distributions package manager. Here's a quick explanation of each dependency and what it offers.

pkg-config

A software dependency management tool for build tools (GNU autotools, make, CMake, etc); Nim-HPX relies on this to point the Nim compiler to your STE||AR HPX installation.

CMake

A software build tool used to compile and install STE||AR HPX

Hwloc

A software library that collects and organizes hardware information from the OS.

tcmalloc

A memory management library that supports multithreaded software. The library usually distributed as part of google-perftools or as tcmalloc-minimal.

PAPI

A software library that provides convenient access to hardware counters implemented in a processor.

Boost

A collection of C++ software libraries that have been vetted by several people involved in the ISO Standards Committee.

APEX

A performance monitoring and measurement library for asynchronous, many-task, runtime systems (AMR/AMT). It provides AMR/AMT the ability to adapt performance during execution.

STE||AR HPX

An asynchronous, many-task, runtime system.

What?

Nim-HPX provides the current API (work-in-progress):

• Locality Information
• Futures, Promises
• Parallel Algorithms
• Local/Remote Asynchronous Function Support
• Local/Remote Asynchronous Method Support
• Distributed Sequences and Coarrays
• SPMD (single-program many-data) Support
• Await/Data-flow
