Hello,
You are right about the number of IP address of the machine. The
cluster has two IP addresses, I thought that the monoprocessor has only
one, but I just
asked the system administrator who told me that it has two also. He
will erase one for the monoprocessot machine, but it is not possible for
the cluster.
How can make the code Lam-MPi cope with a machine that has two IP
addresseS ?
Thank you and best regards,
V. Khiem Truong
