using the modex or RML to share sm initialization information, have node rank 0 create a file containing initialization information in a well-known place. Then during add_procs, the rest of the node processes requiring sm BTL initialization will just read from that file to complete their initialization. This commit was SVN r27789.

[sys call fail]
|
|
A system call failed during sm BTL initialization that should
|
|
not have. It is likely that your MPI job will now either abort or
|
|
experience performance degradation.

[knem requested but not supported]
|
|
WARNING: Linux kernel knem support was requested for the shared memory

(sm) BTL, but it is not supported. Deactivating the shared memory

[knem permission denied]
|
|
Open MPI failed to open the /dev/knem device due to a permissions
|
|
problem. Please check with your system administrator to get the

|
permissions fixed, or set the btl_sm_use_knem MCA parameter to 0 to

run without /dev/knem support.

Open MPI failed to open the /dev/knem device due to a local error.

Please check with your system administrator to get the problem fixed,

[knem get ABI fail]
|
|
Open MPI failed to retrieve the ABI version from the /dev/knem device
|
|
due to a local error. This usually indicates an error in your
|
|
/dev/knem installation; please check with your system administrator,
|
|
or set the btl_sm_use_knem MCA parameter to 0 to run without /dev/knem
|
|
support.

[knem ABI mismatch]
|
|
Open MPI was compiled with support for one version of the knem kernel
|
|
module, but it discovered a different version running in /dev/knem.
|
|
Open MPI needs to be installed with support for the same version of
|
|
knem as is in the running Linux kernel. Please check with your system
|
|
administrator, or set the btl_sm_use_knem MCA parameter to 0 to run
|
|
without /dev/knem support.

[knem mmap fail]
|
|
Open MPI failed to map support from the knem Linux kernel module; this
|
|
shouldn't happen. Please check with your system administrator, or set
|
|
the btl_sm_use_knem MCA parameter to 0 to run without /dev/knem support.
