This release includes a few new plugins and several bug fixes for robustness. Some of the highlights include:

  • Support for InfiniBand UD (in addition to the more common InfiniBand RC).
  • Added support for CMA (Cross-Memory Attach): process_vm_readv and process_vm_writev
  • Improved multi-arch (mixed 32-/64- bit) support.
  • Re-added --enable-fast-restart.
  • Added a new commandline option --with-plugin-32 for dmtcp_launch to specify 32-bit plugins in a 64-bit environment.
  • Added --enable-pthread-mutex-wrappers configure flag to enable pthread_mutex_{lock,unlock} wrappers needed for Open MPI.
  • Added ability to specify environment file used in the modify-env plugin.
  • Allow dmtcp_restart to be invoked by root.
  • The following new plugins were added:
  • pathvirt: to virtualize filesystem paths.
  • delayresume: for finer-grained control over resuming of user threads during resume/restart.
