[Swift-devel] Re: Resume not working in 0.92? Please test.

[Michael Wilde]

OK, very good, Ketan.  Resume worked for me in the old Cray 0.92 version, so if it works in the current one, then that is great.

So I'm assuming that your original suspicion that resume does not work in the latest 0.92+ branch was erroneous.

Please test trunk as well, which is the code version that Allan filed bug 273 against.

I see in your modftdock writeup that when you document resume you did not give the same arguments to swift as in the initial invocation. Those are needed for correct resume behavior. The resume feature assumes that the resumed run is running in the exact same environment as the run represented in the rlog.

If you need it for reference, the original Cray 0.92 version is in /home/wilde/swift/rev/swift-r4143+cog-r3056+pbscoast
(but I see little need to test that rev other than to verify that it exhibits the twice-each bug).
