Hi Frederick,<div><br /></div><div>thanks again for help. So I have tested different simulation variants and I know that the problem occurs when using OMP. For MPI calculations without OMP all tests pass. I have also tested the effect of the <font face="Courier New">`OMP_PROC_BIND` </font>and <font face="Courier New">`OMP_PLACES`</font> parameters and apart from the effect on simulation time, they have no significant effect on the presence of errors. Below are the results for ssmp:</div><div><br /></div><div><font face="Courier New">```</font></div><div><font face="Courier New">OMP_PROC_BIND, OMP_PLACES, correct, total, wrong, failed, time <br />spread, threads, 3850, 4144, 4, 290, 186min<br />spread, cores, 3831, 4144, 3, 310, 183min<br />spread, sockets, 3864, 4144, 3, 277, 104min<br />close, threads, 3879, 4144, 3, 262, 171min<br />close, cores, 3854, 4144, 0, 290, 168min<br />close, sockets, 3865, 4144, 3, 276, 104min<br />master, threads, 4121, 4144, 0, 23, 1002min<br />master, cores, 4121, 4144, 0, 23, 986min<br />master, sockets, 3942, 4144, 3, 199, 219min<br />false, threads, 3918, 4144, 0, 226, 178min<br />false, cores, 3919, 4144, 3, 222, 176min<br />false, sockets, 3856, 4144, 4, 284, 104min<br />```</font></div><div><br /></div><div>and psmp:</div><div><br /></div><div><font face="Courier New">```</font></div><div><font face="Courier New">OMP_PROC_BIND, OMP_PLACES, results<br />spread, threads, Summary: correct: 4097 / 4227; failed: 130; 495min<br />spread, cores, 26 / 362<br />spread, cores, 26 / 362<br />close, threads, Summary: correct: 4133 / 4227; failed: 94; 484min<br />close, cores, 60 / 362<br />close, sockets, 13 / 362<br />master, threads, 13 / 362<br />master, cores, 79 / 362<br />master, sockets, Summary: correct: 4153 / 4227; failed: 74; 563min<br />false, threads, Summary: correct: 4153 / 4227; failed: 74; 556min<br />false, cores, Summary: correct: 4106 / 4227; failed: 121; 511min<br />false, sockets, 96 / 362</font></div><div><font face="Courier New">not specified, not specified, Summary: correct: 4129 / 4227; failed: 98; 263min</font><br /></div><div><font face="Courier New">```</font></div><div><br /></div><div>Any ideas what I could do next to have more information about the source of the problem or maybe you see a potential solution at this stage?
