NAME

       cr_run - runs a subprocess with checkpoint library loaded.

SYNOPSIS

       cr_run [OPTIONS] COMMAND [ARGS]

DESCRIPTION

       cr_run  takes  an arbitrary command and runs it with the "LD_PRELOAD" environment variable set so that an
       appropriate shared library is loaded at program startup.  Such a library must be loaded if  you  wish  to
       take a checkpoint of the process with cr_checkpoint(1).

       cr_run  assumes  that BLCR's libraries (libcr*.so) can be found in the default library search path or via
       the "LD_LIBRARY_PATH" environment variable.

       You do not need to use cr_run if you explicitly link your application with -lcr (you  may  also  need  to
       modify  your  linker's  search  path  with  a  -L  directive, depending on the library's location), or if
       libcr.so or a related library is loaded by other libraries you have linked with (such  as  a  checkpoint-
       ready  MPI  library),  or  by  your  system's  parallel  job  startup  script,  etc.   Check  your system
       documentation for details.

OPTIONS

       -?,--help
              print a usage message and exit.

       --version
              print version information and exit.

       --     ends options processing.

       --omit causes executed process(es) to be omitted (rather than included) in any checkpoint taken.

       --run  overrides any occurance of --omit earlier in the options (restoring the default behavior).

BUGS

       Because cr_run relies on the "LD_PRELOAD" environment variable, it is ineffective  for  statically-linked
       executables, and for setuid/gid programs.
