DMTCP version 1.2.8 is primarily a bug fix release. It is particularly
recommended to upgrade if you are using DMTCP with the ARM CPU,
or if you will compile DMTCP with a C++11 compiler (e.g. GNU flag -std=c++11).
Important changes include:
- Bug fixes for newer ARM CPUs --- especially addressing cache coherency
issues of multi-core ARM, and the more aggressive out-of-order
execution for newer ARM CPUs.
- On restart, gzip zombie processes associated with compressed checkpoint
images were not always reaped properly. This is now handled correctly.
- Peliminary support for using C++11 compilers to compile DMTCP (but
not yet intensively tested).
- Minor bug fixes.
