Dear Sean, I tried with the SVN version, and indeed it works. I tried again with the .tar.gz version, and I confirm that checkpointing doesn't work when using multithreading. It generates correctly the checkpoints, put when you try to resume from a checkpoint, it loads all the history, but then fails to start again the evaluation without printing any error or raising any exception. As far as I could trace it, it stays stuck waiting for a thread. Conclusion: use the SVN version ;) Best regards Marc Le 4 sept. 2013 à 17:36, Marc Segond <[log in to unmask]> a écrit : > > On 04/09/2013 17:29, Sean Luke wrote: > > On Sep 4, 2013, at 11:03 AM, Marc Segond wrote: > > > >> - - launch a run with checkpointing AND more than one thread > >> - - try to load from any checkpoint > >> > >> It gets stuck after loading the checkpoint, seems that it does not > >> succeed to run the evaluation. > > > > Per earlier discussion on this list, did you make the ThreadPool > serializable? > Yes, when it is not Serializable, it raises an error at execution time, > which is not the case. > > > > > > Marc, try the SVN repository version of the code rather than the > tarball on the website. > > > > Sean > I will try. > > Best > > Marc > >
