Hello Bill, Thank you and Kyle for the quick replies to my emails.Warning headed. I am on assignment from the Argonne Leadership Computing Facility (ALCF) on this effort. There is significant interest at ALCF to at least run the CG solvers on BGP (not necessarily ogen). Nevertheless, I will share your sentiment with my assigners.
A question about the perl situation: my initial assessment suggested to me that perl was needed only for configuring the build and running the tests. Since perl is available on the front end, the configuration part should work. Part of my assignment is converting the perl test scripts to, e.g., python. However, your message below makes me doubt my assessment. Are the perl libs, which, as you know, are not available on the back end, needed at run time beyond the test scripts?

Hi Joe,At one time I did get Overture compiled on the BGP front end at ANL with xlc but I was left with the issue that the perl libraries were not available with BGP. We could work aroundthis if necessary but I prefer not too if possible.That said, experience tells me that since we have not run Overture on BGP then you are likely to have problems that will be very hard for you to fix. Therefore this is just a warningthat the path you are on may lead to great misery and despair ... ...Bill J. P.

Returning to the BG/P config issue, I tried to hack : config/A++P++_common_autoconfig.m4 config.subin order to add a Bg/P setup without success. Is there documentation available for adding a machine config? I was not able to find any on the Overture webpage.Best, Joe Bernstein
