Hi, I am new to Xen. I have been experimenting with running mpi over Xen. I would really appreciate if you can tell me how i can install new modules that support IB (Infiniband) over Xen. I started using: mpirun --mca btl openib -np 2 IMB-MPI1 I got the following error:
debian-pristine:~/IMB_3.1/src# /usr/local/bin/mpirun --mca btl openib -np 2 IMB-MPI1 libibverbs: Fatal: couldn't read uverbs ABI version. -------------------------------------------------------------------------- [0,1,0]: OpenIB on host debian-pristine was unable to find any HCAs. Another transport will be used instead, although this may result
in lower performance. -------------------------------------------------------------------------- -------------------------------------------------------------------------- No available btl 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.

As you can see the openib component is there. (see the line in bold)
So then i tried looking if i have all the modules for running IB in my xen image and i found that no modules are installed in the Xen image.
The image that i got is an debian.4-0 from the source: www.jailtime.org. Can any one please tell me how do i go about this problem.
Thanks.
