The good reasons include the difficulties inherent in getting Xen/VMware support for the sometimes odd software found on high-end systems. E.g., on TG-UC, both 64-bit hardware and GPFS have been sources of problems. The bad reason is a persistent conservatism. </font></div><div><font class="Apple-style-span" face="Times"><br></font></div><div><font class="Apple-style-span" face="Times">Good news is that there are a growing number of so-called "cloud" testbeds appearing (albeit small ones), based on Nimbus and Eucalyptus. Also, it seems that Argonne will have a 6,000-core "cloud" system in the near future--a perfect place for such applications. Perhaps that will be first of many.</font></div><div><font class="Apple-style-span" face="Times"><br></font></div><div><font class="Apple-style-span" face="Times">Ian.</font></div><div><br></div><br><div><div>On Apr 24, 2009, at 4:33 PM, Mihael Hategan wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div>On Wed, 2009-04-22 at 12:24 -0500, Michael Wilde wrote:<br><blockquote type="cite">The problem with VMs at the moment is that most of the resources our <br></blockquote><blockquote type="cite">users need to run on at the moment are not VM-enabled, and wont be in <br></blockquote><blockquote type="cite">say the next 12 months or more.<br></blockquote><br>Well, I think that if everybody thinks like that, TG will see no need to<br>do anything about it.<br><br>If we think this is the right way to go (and I do, and you seem to), I<br>believe we should at least ask for it.
