Logs/configuration for succesful run at - вЂ‹, following combinations of jpni & jpnj have been tested and are working fine -ДЄprun -n1080 -N36. While running with jpni x jpnj = jpnij - the simulation (both intel & GCC) runs to completion. This issue shows up only while trying to eliminate land processors (jpni x jpnj > jpnij). Suspecting issues with intel's memory allocation strategy, i tried recompilation of nemo with GNU/GCC compilers, It seems that simulation failed at same point Though, the issue seems similar like - вЂ‹, but i am already using xios-2.0. Relevant xios files & configuration can be located at - вЂ‹ Xios_server.exe 0000000000439D29 Unknown Unknown Unknown Libc-2.22.so 00002AAAAF5386E5 _libc_start_main Unknown Unknown Xios_server.exe 0000000000DD2222 Unknown Unknown Unknown Libpthread-2.22.s 00002AAAAF00EB10 Unknown Unknown Unknown Libifcore.so.5 00002AAAADBE6956 for_signal_handl Unknown Unknown

I recompiled xios-2.0 with intel's traceback option to get some more details on failure, I could see some traceback ( вЂ‹) which indicates some issue with domain.cpp file xios_server.exe to run nemo & xios_server in MPMD mode. Nb of proc with coverage 30 < nb < 50 % -18

Nb of proc with coverage 10 < nb < 30 % 78

Here are more details on combination used : So far, i have tried following combinations and both have failed with similar error message. I have uploaded Error log at bit bucket repo - вЂ‹ > info : If domain grid_T does not have overlapped regions between processes something must be wrong with mask indexД®rror in `./xios_server.exe': free(): invalid pointer: 0x000000000211e490
