Welcome to stopos

What is stopos

Stopos is a tool to manage large number of tasks, mostly started in jobs.

First, you define a 'pool' and fill it with lines (command lines, parameters, ...). Then, tasks (usually in jobs) ask stopos for a line. Stopos takes care that lines that are committed, will not be committed again, unless the user specifically requires to re-commit lines.

Typical usage

  • The user fills a pool with lines, consisting of parameters that are to be used by a program.
  • In a job: as many tasks as there are cores are started in parallel.
  • Each task asks stopos a line: stopos will give each task another line.
  • The task executes the required command using the line as parameter.
  • The task tells stopos that this line is now invalidated, it must not be committed ever again.

Stopos is server-based

Stopos is based on a client-server model. The clients runs on the compute cluster, the server runs on a server node.


Apache 2.0 2004

Download and install

svn co stopos
cd stopos/trunk
# edit the make-script to your taste

After succesfull compilation, there are:

  • stoposclient, the client program
  • stoposserver, the server program
  • stoposzztostr, a program that takes on stdin a hex-encoded string (with pre-and postfix) and outputs the decoded string. This program can be useful when looking at the files on the server side.
  • stoposdump, a script that demonstrates the use of 'stopos dump'.
  • a script makefunction that creates a shell function called stopos. This shell function is normally used when invoking the program. It takes care of setting environment variables.
  • a man page: stopos.1 which describes the usage, also containing an example.
  • modulefile: an example of a modulefile to activate the stopos command. (Only useful if you use modules, but otherwise, it illustrates how to create a suitable alias (called stopos)) for the C-shell
  • a comprehensive description of the program in doc/description.pdf
