[OMPI users] Signal: Segmentation fault (11); Signal code: Address not mapped (1)

[Ken Mighell]

Dear Open MPI gurus,







which spits out a variant of the following message:

[oblix:21522] *** Process received signal ***
[oblix:21522] Signal: Segmentation fault (11)
[oblix:21522] Signal code: Address not mapped (1)
[oblix:21522] Failing at address: 0xc0000710

[oblix:21522] *** End of error message ***


it appears that the bug may be in Open MPI.

Someone has offered what might be a  workaround:

recompile with the following flag:

--with-memory-manager=none

Sadly, that segfaults still occur.

What should we try next?

Best regards,

-Ken Mighell

P.S. mpi_info result follows:

We have F90 code which compiles with MPICH on a dual-core PC laptop using the Intel compiler. We are trying to compile the code with Open MPI on a Mac Pro with 2 quad-core Xeons using gfortran. The code seem to be running ... for the most part. Unfortunately we keep getting a segfault [oblix:21522] [ 0] 2 libSystem.B.dylib 0x92a892bb _sigtramp + 43 [oblix:21522] [ 1] 3 ??? 0xffffffff 0x0 + 4294967295 [oblix:21522] [ 2] 4 exe.out 0x0001281b MAIN__ + 4875 [oblix:21522] [ 3] 5 exe.out 0x00013c38 main + 40 [oblix:21522] [ 4] 6 exe.out 0x00001936 start + 54 After some researching of the error message, and digging around in the Open MPI user's mailing list,
