How To Install dmtcp on CentOS 8
Introduction
In this tutorial we learn how to install dmtcp on CentOS 8.
What is dmtcp
DMTCP (Distributed MultiThreaded Checkpointing) is a tool to transparently checkpointing the state of an arbitrary group of applications including multi-threaded and distributed computations. It operates directly on the user binary executable, with no Linux kernel modules or other kernel mods. Among the applications supported by DMTCP are Open MPI, MVAPICH2, MATLAB, R, Python, Perl, and many programming languages and shell scripting languages. It supports both TCP sockets and InfiniBand connections. With the use of TightVNC, it can also checkpoint and restart X-Window applications. The OpenGL library for 3D graphics is supported through a special plugin. This package contains DMTCP binaries.
