DMTCP: Distributed MultiThreaded CheckPointing

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 nor the operating system.

DMTCP is completely transparent and can checkpoint unmodified Linux binaries. However, if you wish to call DMTCP from within your checkpointed program, we provide an optional programming interface called DMTCP Aware. To use DMTCP Aware:

• Add dmtcpaware.h and dmtcpware.c (or libdmtcpaware.a) to your project. These files can be found in the /usr/lib/dmtcp/ directory if you are using a binary distribution or in the .../dmtcpaware/ directory of the source distribution.
• Include dmtcpaware.h from your code. You should now have access to the DMTCP Aware API.
• Documentation of the DMTCP Aware API functions can be found here. To test if your program is running under dmtcp_checkpoint use dmtcpIsEnabled(). Note that if your program is not running under DMTCP, dmtcpIsEnabled() will return false, and all other API functions will return -128 or NULL and have no effect.
