\section {Data Parallel Code}

There are two parameters that can be changed to alter the resolution
of the grid. They are {\em im }, {\em jm} which are defined in the
header file slgcm.slgprm.  The data parallel code is in the
directory /home/A4F/manu/nasa/BILINEAR/FORALL.  There is no 
equivalent code for bicubic interpolation.

\section {Message Passing Version}

The same two parameters need to be changed as in the Data Parallel code.
They are located in the same file {\em slgcm.slgprm}.  In addition 
another change needs to be made in the file {\em slgcm.mp} to the
variable {\em max\_col }.  The relationship 
between {\em max\_col} and {\em jm}
 is \( max\_col = jm / cmmd\_partition\_size() \).  {\em max\_col} decides the
width of each partition.  

The message passing code is in the directory /home/A4F/manu/nasa/BILINEAR/INT
and /home/A4F/manu/nasa/BICUBIC/INT.
