without knowing of what nature exactly your communication problems are,
it's hard to suggest something that would solve these problems.

But since you asked about a suggestion for a replacement of Pelican HPC
(which is end-of-life anyhow) you might find Qlustar (qlustar.com) an
attractive replacement. It also supports Debian as a compute platform
as well as diskless cluster nodes out of the box, just like
Pelican. Since the node OS is running in RAM (rather than with NFS root)
it is definitely much less susceptible to network communication
problems. It's easy to try it out: A head-node + virtual demo cluster is
installed in less than an hour. Qlustar is free for pure academic and
non-commercial use and very attractively priced for other cases.
