alternative to expect

I am using the intel cluster toolkit to run a cluster. However I am getting errors during the installation of the expect software.
It does not recognize the operating system which is RedHat enterprise Server 5.0

Is there any alternative software to the expect software to establish the ssh connectivity between the machines?

Kindly help

Intel Network Latency

Hello,

This is my first post to the group.

I am not really a software developer, more a learning Network Architect recently working in a HPC-type field. I have become very interested in this field recently and hope to give back to the community as I learn more myself.

I hope someone will be able to provide more info or link to some sites regarding my questions. If you don't have any answers, maybe some suggestions on how I could find the answer out myself...

mpi on Vista 64 mapped drive

Running on a shared memory machine, and in a current directory j:\myprog - where J: is mapped tp c:\users\john\documents, I discovered that all the mpi instances report the current directory as c:\windows\system32. After some hair loss, I tried switching to the canonical directory - c:\users\john\documents\myprog - and it works. It also works if I use -wdir to specify the canonical directory, but not if I use the mapped drive with -wdir.

Is this a bug?

So, ifsomeone hasa example or usage, addition information(except

MPI process interactive start-up and fault tolerance

I am relatively new to MPI programming.

I am wondering how I can start up each process manually within the same MPI communicator world space.

In addition, when only a single process fails, how can this be detected and relaunched automatically, without crashing the other processors and the host?

Hope somebody can advise on this two issues. Thanks
