<P><FONT SIZE=2 FACE="Arial">Hello,</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">We are trying to run the Monte Carlo code MCNP with MPICH2. However, we are having problems with jobs bigger than 2 gigabytes. The jobs we want to run are as big as 9 gigabytes. We are running the jobs on a linux system with 64-bit operating system.</FONT></P>
<P><FONT SIZE=2 FACE="Arial">Are there any limits to the size of the files that MPICH2 could handle? Are there any options that we need to set for MPICH2 to handle such large jobs?</FONT></P>
<P><FONT SIZE=2 FACE="Arial">Your help would be greatly appreciated.</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">Thanks,</FONT>
