JUMP-Linux

Introduction

JUMP-linux is a Software Distributed Shared Memory (SDSM) for Linux.

It is based on JUMP [1] which, in turn, is based on JIAJIA 1.1. According to [1] JUMP has better performance of JIAJIA either version 1.1 and 2.1.

This version has been modified to run only on modern Linux systems, supporting i386, x86_64, ARM and ARM64 architectures. The porting activity has been done in the context of the AXIOM EU project [2].

The copyright is specified by the COPYING file.
