+h1. Tutorial: Parallel Crunch tasks
 
 In the tutorial "writing a crunch script,":tutorial-firstscript.html our script used a "for" loop to compute the md5 hashes for each file in sequence.  This approach, while simple, is not able to take advantage of the compute cluster with multiple nodes and cores to speed up computation by running tasks in parallel.  This tutorial will demonstrate how to create parallel Crunch tasks.

 Because the job ran in parallel, each instance of parallel-hash creates a separate @md5sum.txt@ as output.  Arvados automatically collates theses files into a single collection, which is the output of the job:

 h2. The one job per file pattern
 
-This example demonstrates how to schedule a new task per file.  Because this is a common pattern, the Crunch Python API contains a convenience function to "queue a task for each input file":crunch-utility-libraries.html#one_task_per_input which reduces the amount of boilerplate code required to handle parallel jobs.
