I resolved the name resolution issue and re-ran it but it still hangs at
the send-receive calls.
I ran it using:
/usr/local/bin/mpirun --mca btl_tcp_port_min_v4 36900 -mca
btl_tcp_port_range_v4 32 --mca btl_base_verbose 30 --mca
OMPI_mca_mpi_preconnect_all 1 -np 2 -hetero -H localhost,10.11.14.2

I did try to ping using the hostname but i can't..can that be an issue..??
both of them are sitting on the same subnet !!! let me check if i can

Hmm,
On another angle, could this be a name resolution issue? Perhaps apex-backpack
isn't able to resolve fuji.local and visa versa. Can you ping between the two of
them using their hostnames rather then their IPs?

Yes it came up when i put the verbose mode in i.e. the debug output..
yes i knew its privileged so thats why i explicity asked it to connect to
a higher port but still it blocks there..:(

Port 4? OMPI should never connect at port 4; it's privileged. W

Hi All,

I have tried other wireless adapters as well. But no luck till far.
Please let me know what can be done...

According to your debug output:
[apex-backpack:31956] btl: tcp: attempting to connect() to address
10.11.14.203 on port 9360
It *is* trying to connect to the right IP address
