This adds the code to actually checkpoint a process using CRIU
with the necessary variables to control the behaviour.
Right now only --np 1 is supported and --mca oob tcp.
Following parameters are supported:
* crs_criu_log: name of the log file
* crs_criu_log_level: verbosity level in the log file
* crs_criu_tcp_established: C/R established TCP connections
* crs_criu_shell_job: C/R shell jobs
* crs_criu_ext_unix_sk: allow external unix connections
* crs_criu_leave_running: leave tasks in running state after checkpoint
This commit was SVN r30772.
* Remove redundant/unnecessary uses of $2
* Change a bunch of logic from negative to positive
* Use OPAL_VAR_SCOPE_PUSH/POP to help reduce env var usage
* Only use "" in test statements with strings that require sanitization
* Removed redundant AC_MSG_WARN/ERROR. There's now only one check at
the bottom for whether the component is "good" or not. We'll
AC_MSG_WARN/ERROR in that one location.
Thanks to Jeff Squyres for this patch.
This commit was SVN r30739.
To be able to checkpoint/restart using criu (criu.org) a new
CRS component is added which is based on criu. This first commit
provides the minimal set of functions and configure script options
to enable --with-criu and link against libcriu.so.
No actual checkpoint/restart functionality is yet implemented.
This is only the framework which needs to be filled with the
actual functionality.
This commit was SVN r30666.
