My students and I are interested in setting up a parallel java (PJ) cluster (http://www.cs.rit.edu/~ark/pj.shtml). These are my advanced independent study students who just spent a year working with MPI & OpenMosix using C & C++. MPI is getting a bit dated and the OpenMosix project just closed, so they want experience with a new kind of cluster/grid paradigm.
Anyway, we've complied with all the installation requirements for PJ (http://www.cs.rit.edu/~ark/pj/doc/edu/rit/pj/cluster/package-summary.html middle of page) except for the following:
Furthermore, it must be possible to do an SSH remote login from the frontend processor to each backend processor without the user having to type a password. This is done using public key authentication. SSH must have public key authentication enabled. Each user must set up SSH public and private keys in his or her account. For further information, refer to the SSH documentation.
I have sshd running, but I don't have any experience with "public key authentication." Anyone out there have any suggestions or tips for this?
TIA,
AJG
