[Error]= [ 0] /lib/x86_64-linux-gnu/libc.so.6 when using mpirun

[remit]

Dear community,

I managed to generate a romsM file after setting the bash file and setting the openmpi directory used.
But when I run the process using:

Code: Select all

mpirun -np 9 ./romsM roms_file.in

and of course i set NtileI as 3 and NtileJ as 3

I got the error:

Code: Select all

[LAPTOP-U4JKE22G:03951] *** Signal receiving process ***
[LAPTOP-U4JKE22G:03951] Signal: Segmentation fault (11)

[LAPTOP-U4JKE22G:03951] *** End of error message ***
Segmentation fault

In case of romsS I managed to running roms with perfectly, but in the case of romsM I got problem like the above. Can someone help me to solve this problem?

make sure that the mpirun you are using is from the same openmpi directory that you compiled with. For example, if you are compiling with

Code: Select all

/self/compiled/openpmi/bin/mpif90

make sure that the command

Code: Select all

which mpirun

returns

Code: Select all

/self/compiled/opempi/bin/mpirun

and not something like

Code: Select all

/usr/bin/mpirun

If the paths to mpif90 and mpirun match then recompile with USE_DEBUG = on in your build_roms.sh. Then run the model with:

Code: Select all

mpirun -np 9 ./romsG roms_file.in

and see if you get a more useful error message.

tks robertson,
My mistake was to let compile read openmpi in its default position, which is usr/bin/mpirun
Thanks for your suggestion
