Thanks ron for your reply. I have mailed Dan and I am going through
and trying to 'understand' the conversation <
http://gridengine.sunsource.net/ds/viewMessage.do?dsForumId=38&dsMessageId=88197>

Can you or any one else comment on the rest of the ideas I mentioned
in my last mail.
I will appreciate that.
Waiting for replies.
Thanks
