Henk,
It was supposed to work ... Apparently we had a bug on the PML
selection when ^ was used. It is corrected now in the trunk. Until you
upgrade to the latest version (> 18683), you can specifically ask for
the OB1 PML. Please add OMPI_MCA_PML = ob1 to your script.

Hi George
I believe this got lost in my previous reply. I followed your
suggestion
and got a different error message:
------------------------------------------------------------------------
--
No available pml components were found!
This means that there are no components of this type installed on your
system or all the components reported that they could not be used.
This is a fatal error; your MPI process is likely to abort. Check the
output of the "ompi_info" command and ensure that components of this
type are available on your system. You may also wish to check the
value
of the "component_path" MCA parameter and ensure that it has at least
one directory that contains valid MCA components.
------------------------------------------------------------------------
--
[node258:13595] PML ^cm cannot be selected
------------------------------------------------------------------------
--
These are the lines in my GridEngine script:
setenv OMPI_MCA_btl "openib,self,sm"
setenv OMPI_MCA_pml "^cm"
mpirun -np $NSLOTS $exe
The run appears to fail.
Am I doing something wrong here?
Thanks
Henk

Subject: Re: [OMPI users] Error in mx_init message
This is a different issue. On top of Myrinet, Open MPI support two
nodes: cm and the others. Basically, the difference is how
the card will be used. If you only specify the btls then Open
MPI will try to initialize the CM PML and that's how this
error message appears. If you add OMPI_MCA_pml=^cm to your
environment, then this warning will go away.

I have OpenMPI-1.2.5 configured with myrinet and infiniband:
OMPI_MCA_btl=openib,self,sm
The job runs with the "error" message
"Error in mx_init (error MX driver not loaded.)"
which makes sense in itself as there is no myrinet card on the node.
Is it correct to assume that the ib interconnect will be
used anyway?
I saw an old email with a similar query and a comment that this
message would be removed in a future release, has that happened yet?
Thanks
Henk
