Dear Nick Sir, Thank you for your guidance. Which one should I use for all the compilations? mpich or openmpi? I have tried using openmpi for all compilations, blacs and siesta and the other related packages. Then the installation gets completed error free, but which running siesta in parallel, I get the following error message:
*Program received signal SIGSEGV: Segmentation fault - invalid memory reference.Backtrace for this error:Program received signal SIGSEGV: Segmentation fault - invalid memory reference.Backtrace for this error:Program received signal SIGSEGV: Segmentation fault - invalid memory reference.Backtrace for this error:Program received signal SIGSEGV: Segmentation fault - invalid memory reference.Backtrace for this error:#0 0x7FB354DAA6F7#1 0x7FB354DAAD3E#2 0x7FB35409326F#0 0x7F6E0BF3B6F7#1 0x7F6E0BF3BD3E#2 0x7F6E0B22426F#3 0x7FB35510DE2A#3 0x7F6E0C29EE2A#0 0x7F94B84896F7#1 0x7F94B8489D3E#2 0x7F94B777226F#3 0x7F94B87ECE2A#0 0x7F6CDA7CF6F7#1 0x7F6CDA7CFD3E#2 0x7F6CD9AB826F#3 0x7F6CDAB32E2A#4 0x7319B3 in BI_TransUserComm#5 0x72B476 in blacs_gridmap_#6 0x72B1B8 in blacs_gridinit_#4 0x7319B3 in BI_TransUserComm#7 0x4AE8AC in cdiag_ at cdiag.F:247#5 0x72B476 in blacs_gridmap_#4 0x7319B3 in BI_TransUserComm#8 0x434AD1 in diagk_ at diagk.F:177#6 0x72B1B8 in blacs_gridinit_#5 0x72B476 in blacs_gridmap_#9 0x4230FE in diagon_ at diagon.F:305#4 0x7319B3 in BI_TransUserComm#6 0x72B1B8 in blacs_gridinit_#5 0x72B476 in blacs_gridmap_#10 0x4C584E in __m_compute_dm_MOD_compute_dm at compute_dm.F:60#6 0x72B1B8 in blacs_gridinit_#11 0x4DD8A5 in __m_siesta_forces_MOD_siesta_forces at siesta_forces.F:80#7 0x4AE8AC in cdiag_ at cdiag.F:247#7 0x4AE8AC in cdiag_ at cdiag.F:247#8 0x434AD1 in diagk_ at diagk.F:177#8 0x434AD1 in diagk_ at diagk.F:177#9 0x4230FE in diagon_ at diagon.F:305#7 0x4AE8AC in cdiag_ at cdiag.F:247#9 0x4230FE in diagon_ at diagon.F:305#10 0x4C584E in __m_compute_dm_MOD_compute_dm at compute_dm.F:60#8 0x434AD1 in diagk_ at diagk.F:177#10 0x4C584E in __m_compute_dm_MOD_compute_dm at compute_dm.F:60#11 0x4DD8A5 in __m_siesta_forces_MOD_siesta_forces at siesta_forces.F:80#11 0x4DD8A5 in __m_siesta_forces_MOD_siesta_forces at siesta_forces.F:80#9 0x4230FE in diagon_ at diagon.F:305#10 0x4C584E in __m_compute_dm_MOD_compute_dm at compute_dm.F:60#11 0x4DD8A5 in __m_siesta_forces_MOD_siesta_forces at siesta_forces.F:80--------------------------------------------------------------------------mpirun noticed that process rank 2 with PID 0 on node loadbalancer exited on signal 11 (Segmentation fault).* Please help me out in this regard. What does the error mean and how can it be solved? Thank you. Respectfully, Sunetra Das
