Hi, I have a parallelized Mathematica program that spans across 8 MathKernels processes running at 100% and one MathKernel (highlighted in blue) running at < 10% that controls the other 8. They look like this on the cluster:
I want to run these process indefinitely, but after a while, because of a Mathematica bug, the program continues to run at 100%, but stop giving me results.
One way to solve that is to kill the the controller MathKernel process (automatically the other 8 process are killed) and start again.
I would like a help on how to make a script that runs a command "C" and then after some time "X" kills the process belonging to me (giovform) called "MathKernel" running at < 10% cpu and then runs "C" again, all this in a loop. Is this possible? Sorry for asking too much..
I am using nohup to execute my commands so I can close the terminal window without killing them.

Is there any functional difference between:
issuing separate stop/start commands like this;
super (handler) (instance) stop
super (handler) (instance) start
versus issuing a single recycle command like this;

Another question for you guys! This is so fun.
So I am playing around with the factor operation. I read in "man factor" that you can actually print a list of primes in between a range, using the syntax
factor ]
However, every time I enter two values, it just returns the factored value.... (1 Reply)

pidof
PIDOF(8) Linux System Administrator's Manual PIDOF(8)NAME
pidof -- find the process ID of a running program.
SYNOPSIS
pidof [-s] [-c] [-n] [-x] [-o omitpid[,omitpid..]] [-o omitpid[,omitpid..]..] program [program..]
DESCRIPTION
Pidof finds the process id's (pids) of the named programs. It prints those id's on the standard output. This program is on some systems
used in run-level change scripts, especially when the system has a System-V like rc structure. In that case these scripts are located in
/etc/rc?.d, where ? is the runlevel. If the system has a start-stop-daemon (8) program that should be used instead.
OPTIONS -s Single shot - this instructs the program to only return one pid.
-c Only return process ids that are running with the same root directory. This option is ignored for non-root users, as they will be
unable to check the current root directory of processes they do not own.
-n Avoid stat(2) system function call on all binaries which are located on network based file systems like NFS. Instead of using this
option the the variable PIDOF_NETFS may be set and exported.
-x Scripts too - this causes the program to also return process id's of shells running the named scripts.
-o omitpid
Tells pidof to omit processes with that process id. The special pid %PPID can be used to name the parent process of the pidof pro-
gram, in other words the calling shell or shell script.
EXIT STATUS
0 At least one program was found with the requested name.
1 No program was found with the requested name.
NOTES
pidof is actually the same program as killall5; the program behaves according to the name under which it is called.
When pidof is invoked with a full pathname to the program it should find the pid of, it is reasonably safe. Otherwise it is possible that
it returns pids of running programs that happen to have the same name as the program you're after but are actually other programs. Note
that that the executable name of running processes is calculated with readlink(2), so symbolic links to executables will also match.
