1) You should already have ~/cvs if you did hw1.

2) Import the hw2 tree into your cvs with the following:
   $ cd /cluster/home/cs240a/bin/hw2 
   $ cvs  -d ~/cvs import -m "Initial import"  hw2 hw2 START 
   $ cd ~
   $ cvs -d ~/cvs co hw2

3) This will initialize your hw2 cvs tree. 

   Now, to compile mpi, use
   $ make mpi REASON={1-6} [WORK=n]

   To use the Matlab *P hookup, first do 'make mpi' and getresv. Then
   $ make starp

   This allows you to test your code by just writing the code in
   hw2sort.cc (without writing any I/O code). Just saying
   
   >> x = rand (1e5*p,1) 
   >> y = hw2sort (x)

   will create a random test input and call your parallel sorting code 
   in hw2sort.cc.

4) To turnin your homework
   $ make turnin

   You can do this multiple times. The last one only will be graded.
