Okay, now that I can finally post here, I can suggest we try to shift the discussion about Chasm and standardized array interop back to this list, where the interested parties can see it, and where it gets archived for posterity. To summarize recent discussions amongst CCAers about this topic: 1) Chasm has fallen behind in support for the latest compiler versions on a number of platforms, especially 64-bit. This is an immediate issue that needs to be addressed. 2) The Babel folks need to understand whether what's been proposed for F2008 really covers everything they've been getting from Chasm thus far. (Also, I guess the previous draft stuff that some vendors have already implemented.) 3) Assuming the F2008 stuff is an appropriate replacement, Babel needs to extended to support it -- testing the compiler for support in autoconf, and generating the appropriate code. 4) We need for Chasm to be maintained until users upgrade to compiler versions supporting the F2008 features. Just because a site has a compiler version that does support the needed features, doesn't mean the users are actually using that version. Many sites, especially large centers, maintain multiple compiler versions simultaneously. So I think we need to figure out an approach that covers these bases. Are there any other major users of Chasm, besides Babel/CCA, who we should try to draw into this discussion? -- David E. Bernholdt | Email: ber...@or...
