Latest results on my experimentation here. Short form: rc1 seems to work on Atom N550, but still not rc2 or rc3.
For some reason, finally seem to have gotten a saved checkpoint that works all the time on the Fedora 20 (kernel 3.17.7) i3 540, with rc2. Ran it about 50 times in a row with no segfault. Also have tried building and running each of 2.3.1 and 2.4.0 rc1, rc2,rc3 on the Fedora 19 (kernel 3.14.23) Atom N550. Results: 2.3.1 works like the packaged version, but that means control-c ends all checkpointed shells tested with (R,python,ocaml). rc2 and rc3 (just put up for download hours ago) still crash on every checkpointed shell at the same place shown with strace. However, *rc1* *works* each time I try on each of these shells, and handles control-C correctly with R and Python. However, with ocaml, when one hits control-C, ocaml prints its "interrupted" message (so the signal does get to it fine) but then the whole thing quits. Now, I noticed that ocaml is actually bytecode for the ocaml interpreter, run by the shell using a bang line. That could easily mess things up, I suppose. So I tried a checkpoint running the ocaml bytecode interpeter directly, passing ocaml into it. And... that seems to work. Tried it many times in a row. Runs okay (after loading in a huge ocaml program) and control-c works as it should. So hopefully this is some kind of clue. I assume rc1 works on this system. But, rc2 and rc3 don't. Without any understanding of what these programs truly do I don't know what other information I can provide but will try to provide more if told what I could gather. Maybe it is just something in the configure/make that differs? ------------------------------------------------------------------------------ One dashboard for servers and applications across Physical-Virtual-Cloud Widest out-of-the-box monitoring support with 50+ applications Performance metrics, stats and reports that give you Actionable Insights Deep dive visibility with transaction tracing using APM Insight. http://ad.doubleclick.net/ddm/clk/290420510;117567292;y _______________________________________________ Dmtcp-forum mailing list Dmtcp-forum@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/dmtcp-forum
