Dear QE users,
I am trying to perform relax calculations on a supercell with 1296
atoms. I will show two different codes for two different lattices at
the end of this message, why two will be clear in the following. In
the terminal I run the following command
mpirun -use-hwthread-cpus '/usr/bin/pw.x' <relax.in> relax.out
and I receive the error *** buffer overflow detected ***: terminated.
Now, a relax.out file is indeed created, but it is not finished. I
tried to check for memory issues using Valgrid with the following
command
mpirun -use-hwthread-cpus valgrind --leak-check=full
--track-origins=yes '/usr/bin/pw.x' < relax.in > relax.out
but I received the following summary which did not help me any further.
==6066== LEAK SUMMARY:
==6066== definitely lost: 3,460 bytes in 113 blocks
==6066== indirectly lost: 63,745 bytes in 67 blocks
==6066== possibly lost: 5,304 bytes in 5 blocks
==6066== still reachable: 7,572,489 bytes in 29,125 blocks
==6066== suppressed: 0 bytes in 0 blocks
==6066== Reachable blocks (those to which a pointer was found) are not shown.
==6066== To see them, rerun with: --leak-check=full --show-leak-kinds=all
==6066==
==6066== For lists of detected and suppressed errors, rerun with: -s
==6066== ERROR SUMMARY: 19 errors from 19 contexts (suppressed: 0 from 0)
Now, I thought that this issue might be resolved by trying a smaller
lattice. So I wrote a smaller lattice with only 48 atoms. In this case
I got the same error in the same manner. Does somebody know what I can
do to solve this issue, or what I might be doing wrong.
Kind regards,
Cristian Sierra.
