Hi,
I checked the user document and MAN pages yet.
But,,, regrettable,,, I can't understand the usage of cr self module.
If a code is ...
-------------------------------------------------
int cr_restart(void)
{
std::cout << "test restart" << std::endl;
return 0;
}
main(int argc, char* argv[])
{
/* Start up MPI */
int provided = MPI::Init_thread(argc, argv, MPI::THREAD_SERIALIZED);
//some MPI procedure...
while(false){
cr_restart();
}
//some MPI procedure...
/* Shut down MPI */
MPI::Finalize();
} /* main */
-------------------------------------------------
and
$ mpic++ -O0 test.cpp
$ lamboot -ssi rpi crtcp
$ lamrestart -ssi cr self -ssi cr_self_restart_args "-ssi cr_self_prefix cr -np 2 ./a.out"
.
Should an output prompt show "test restart" ?
In addition... man page for lamrestart and lamrestart prompt contain typo.
cr_restart_args -> cr_self_restart_args
Thanks.
