** DMTCP (Distributed MultiThreaded Checkpointing) is a tool to transparently checkpointing the state of an arbitrary group of programs spread across many machines and connected by sockets. It does not modify the user's program or the operating system.
* Improved support for OpenMPI 1.3 and 1.4
* dmtcp_restart_script.sh allows user specified hostnames on restart.
* dmtcp_command now supports blocked checkpoint mode.
* Several other bug fixes and improvements.
Internally tested on:
Ubuntu 9.10, Debian sid, OpenSuse 11.2, CentOS 5.4 (Red Hat)
