Two questions, first on the Cluster Studio installation.
In the document, software "expect" is needed to make the ssh connectivity between nodes of the cluster. However, in my current cluster, all my nodes can ssh to each other without password. I wonder whether I can skip this "expect" requirement, since I do not want to complicate the existing ssh environment.
Second question, on using Intel MPI
After I installed on each node, I can use mpirun to test run MPI code on one node without problem, I can also use mpirun within SGE script to run MPI job across nodes without problem. But if I try to run mpiexec on a node, I get errors below. Could anyone give a hint of what is wrong? Thanks a lot!
[compute-0-2 FD3DVer1.0]mpiexec -np 2 -host localhost ./fd3dmpiVer1Debug
mpiexec_compute-0-2.local: cannot connect to local mpd (/tmp/mpd2.console_lichen); possible causes:
1. no mpd is running on this host
2. an mpd is running but was started without a "console" (-n option)
