10.1 TaskFarming Examples

• Code Mode Suppose the TaskFarmer is installed in the home directory on node0. Suppose you want to run in code mode an executable named task. Your Master machine is called node0. You want to run five different jobs on a network of four machines, say. For each job you create an input file with extension .in called input1.in, input2.in...input5.in. The run will look like:

  node0% perl tf.pl
  
  **************** TaskFarmer version 2.1 ****************
  
  Are you submitting matlab jobs [(Y)es, (N)o, or (Q)uit]? n
  Enter the PATH of executable (or (Q)uit) < task
  An email will be sent to you upon the completion of the submitted jobs.

• Script Mode Suppose the TaskFarmer is installed in the home directory on node0. Suppose you want to run in script mode a matlab script named driver.m which is in the directory MR. Want to run five jobs on four machines, corresponding to input files input1.in, input2.in, ..., input5.in. The run will look like:

  node0% perl tf.pl
  
  **************** TaskFarmer version 2.1 ****************
  
  Are you submitting matlab jobs [(Y)es, (N)o, or (Q)uit]? y
  Enter the PATH of the matlab directory (or (Q)uit) < MR/MR1
