<div dir="ltr">Hi Maksim,<div><br></div><div>This sounds rather bizarre I'll admit. I think I've occasionally had a similar such problem but it was a long time ago and possibly only during initialization. I also think it had to do with a certain combination of MPI + HDF5 versions I used then.</div><div><br></div><div>In any case, does this happen at the same time step every time? If so, you can set the following parameters in your flash.par:<br>wall_clock_checkpoint</div><div>wall_clock_time_limit (to avoid burning computer time)</div><div><br></div><div>as well as setting `checkpointFileIntervalStep` to a value to restart just before the hangup.</div><div><br></div><div>Once you're right about at the hangup spot, you can compile in debug mode and use a parallel debugging tool to investigate (or write lots of print statements ;)</div><div><br></div><div>Best of luck,<br clear="all"><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div dir="ltr">--------<div>Ryan</div></div></div></div></div></div></div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Jun 7, 2022 at 4:20 AM Maksim Kozlov <<a href="mailto:maksim.kozlov@nu.edu.kz">maksim.kozlov@nu.edu.kz</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">Dear Flash users,<div>my code works perfectly until some point. It displays executed time steps one after another. Then after some time step it does not show a new time step. I stopped my code and relaunched it. Same result - it shows the same last time step and then nothing happens. Code does not stop working, no warning messages appear, but a new time step is never displayed - I waited for about 18 hours - nothing. I would really appreciate any suggestions on what can cause this problem and what I can do to resolve it.</div><div>Thank you very much!</div><div>Maksim Kozlov</div></div>
