Here's the configuration:
One CISCO gigabit Ethernet switch. Plugged into this switch is
zappa.georgetown.edu, which is the master node of a 16 node OSCAR
Beowulf cluster, hendrix.arc.georgetown.edu, which is a stand-alone
computer (that also answers to time.arc.georgetown.edu), and
john.arc.georgetown.edu, paul.arc.georgetown.edu,
george.arc.georgetown.edu and ringo.arc.georgetown.edu, which are all
stand-alone nodes that happen to share a filesystem and use PVM, but
they are NOT a classic Beowulf cluster. I have other machines elsewhere
on campus all running gmonds.
Here's the problem: hendrix is my only gmetad installation (you can see
it at www.guppi.georgetown.edu), and it is supposed to report on all
clusters and all stand-alone machines on my 'grid.' Clusters report
their Master node on the top-level, and you can tunnel down to see the
compute nodes. This has been working just fine up until now.
When I tried to add john, paul, george and ringo, and have them send
their data to hendrix to be displayed, each of them will speak for
themselves, as well as for each other, AND hendrix (or time)!! For
example, john (which is a dual-processor machine) will report that it
has 5 nodes and 10 processors, and if you tunnel down on john you'll
find john (again), george, paul, and ringo, as well as either hendrix or
time. Additionally, hendrix will not report for itself. I've tried
making each of these machines 'deaf' in the config file, but then they
disappear entirely.
What am I doing wrong? Things have been going so well with ganglia here
up until now, but I don't see anything in the docs to help me. How can
I make each of these machines ignore the others and just report their
local information to hendrix?? At first I thought it was an issue with
sharing the switch, but if it were zappa would be involved. Then I
thought it was a PVM thing, but then why is hendrix involved???
