It depends on what "right" is in your environment. :-)
Your default config excludes the B
Yes, it's right!
Now i can see btl_tcp_if_include flag:
MCA btl: parameter "btl_tcp_if_include" (current value: , data source:
default value)
MCA btl: parameter "btl_tcp_if_exclude" (current value: "eth0,ib0,ib1", data
source: file

Ah ha... this is revealing:

Ok,
this is my output:
ompi_info --param btl tcp
MCA btl: parameter "btl_base_verbose" (current value: "0", data source:
default value)
Verbosity level of the BTL framework
MCA btl: parameter "btl" (current value: "^tcp", data
source: file

Oops! I neglected to see that you built statically -- hence, all the OMPI
plugins got slurped up into their respective libraries (e.g., libmpi.a).
If you run ompi_info --param btl tcp, do you see anything at all? If not, that
would indicate that the TCP BTL wasn't built. IF so, can you send
MM,
my OpenMPI installation haven't this library.
Ho can i do to install it? It is very important? Or i can use OpenMPI
without this module?

Check in your installation directory under $lib/openmpi -- see if mca_btl_tcp.*
is there. There should be a .so file (and probably a .la file as well). If
the .so is not there, then the BTL TCP plugin is not installed (which would be
darn weird, to be honest...).

Hi Jeff,
thaks for your reply!
If i set yout command the response is empty.
This means i haven't installed TCP BTL plugin?
How can i check it?
These are my build flags:
--disable-ipv6 --disable-dlopen --enable-static --with-openib
--with-memory-manager=none --with-mpi-f90-size=medium
--with
No, that param is still there:
$ ompi_info --param btl tcp --parsable | grep clude:
mca:btl:tcp:param:btl_tcp_if_include:value:
mca:btl:tcp:param:btl_tcp_if_include:data_source:default value
mca:btl:tcp:param:btl_tcp_if_include:status:writable
mca:btl:tcp:param:btl_tcp_if_include:help:Comma-delimi
Dear OpenMPI users and developers,
I'm trying OpenMPI 1.3.3 and i've noted that btl_tcp_if_exclude is not
supported from new version:
the response to this command:
ompi_info --param all all | grep btl_tcp_if_exclude
is empty.
Maybe that params is renamed?
Thanks in advance
