PROGRAM:

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).
