[Fwd: Re: eofgrads]

[Dr. Parthasarathi Mukhopadhyay]

Hi Matt,
I am thankful to you. The EOF has worked in our SGI machine. We have initially not
succedded by using the eofudf executable that comes with the tar file, we downloaded the
source code and recompile and use the executable created and that runs OK.
Thanks for your help.
