at, batch, atq, atrm - queue, examine or delete jobs for later execution
at [-V] [-q queue] [-f file] [-mldbv] TIME
at [-V] [-q queue] [-f file] [-mldbv] -t time_arg
at -c job [job...]
atq [-V] [-q queue]
atrm [-V] job [job...]
at and batch read commands from standard input or a specified file which are to be executed at a later time.
at executes commands at a specified time.
atq lists the userís pending jobs, unless the user is the superuser; in that case, everybodyís jobs are listed. The format of
the output lines (one for each job) is: Job number, date, hour, queue, and username.
atrm deletes jobs, identified by their job number.
batch executes commands when system load levels permit; in other words, when the load average drops below 0.8, or the value speci-
fied in the invocation of atd.
Then write a simple script:
mpiexec <first job>
mpiexec <second job>
and run it using one of the at-like commands.
