<h1>Unix Tools on Massively Parallel Processors</h1>

<p>
The introduction of parallel processors that run a separate  
copy of Unix on each process has introduced new problems in managing the  
user's environment.  This paper discusses some generalizations of common  
Unix commands for managing files (e.g. <tt>ls</tt>) and processes (e.g.  
<tt>ps</tt>) that are convienient and scalable.    
These basic tools, just like their Unix counterparts, are text-based.   
We also discuss a way to use these with a graphical user interface (GUI).  
Some notes on the  
implementation are provided.  Prototypes of these commands are  
publically available.
