Interesting point - no reason why we couldn't use that functionality for this purpose. Good idea! On 7/11/07 5:38 AM, "Jeff Squyres" wrote: > On Jul 10, 2007, at 1:26 PM, Ralph H Castain wrote: > >>> 2. It may be useful to have some high-level parameters to specify a >>>

Point taken. Is this an accurate summary? 1. "Best practices" should be documented, to include sysadmins specifically itemizing what components should be used on their systems (e.g., in an environment variable or the system-wide MCA parameters file). 2. It may be useful to have some

Actually, I was talking specifically about configuration at build time. I realize there are trade-offs here, and suspect we can find a common ground. The problem with using the options Jeff described is that they require knowledge on the part of the builder as to what environments have had their
