Just now I try to make a calculation at supercomputer with a random <br>
structure for testing, I passed already some problems, but sometimes I <br>
still meet errors, and there is no nonzero files. I am attaching three <br>
files:<br>
1. slurm*out, where errors are shown, the first one before lapw0 didn't <br>
affect, do not know why?, lapw0 was calculated, all output files are <br>
good. lapw1 was not calculated.<br>
<br>
2. *.dayfile I can see that lapw1 was not calculated only by too small <br>
times:<br>
tesla46(6) 0.006u 0.010s 0.75 2.11% 0+0k 0+0io 0pf+0w<br>
(the next lines are my additional output inserted into lapw1para:<br>
1 t taskset0 exe def_loop.def time srun 0 lapw1 lapw1_1.def)<br>
<br>
3. ls-l.output shows that all the *.error files are zero, and the files <br>
that should be done by lapw1, are absent.<br>
<br>
Doesn't matter why the task didn't calculated, but why the <br>
lapw1*.error's are zero?<br>
I sent for testing run -e lapw1, otherwise it would have come to lapw2 <br>
without stopping.<br>
<br>
