Dear List,
I've installed OGE on a mini-cluster of iMacs running OS X 10.6.8, and it seems
to be
working but with one semi-major glitch. (Why iMacs, you ask...well, they are
what I
inherited from a guy that moved his lab...5 iMacs and various other boxes.)
I compiled the OGE source locally, and that went great after I tweaked it to
find
darwin-x64 and whatnot. Installation went great, following the wonderful
install vids
that have been posted for GE on Mac OS X. I have qmaster running on
dhcp80fff96b, with
three execution hosts (dhcp80fff96b, dhcp80fff9b6, and dhcp80fff90d), and an
NFS share
between them (where GE resides). Passwordless ssh is enabled for the GE owner,
so the
boxes should be able to communicate.
This shouldn't be necessary for the operation of OGE - just for the
installation it *might* be necessary (but you can also do it without by local
installations).
Thanks. I was thinking of MPI jobs and communicating between nodes.
So, this is where the problems arise: in all.q, the execution host on the
master node
running qmaster throws an E status.

I can submit jobs and they will be successfully farmed out to the external
execution
hosts, so it would seem that everything is fine and dandy. Meanwhile, the
execution
daemon is working on the master node.

I've tried just about everything (even rebooting the master node), and nothing
seems to
solve this. I've looked in the spool messages to troubleshoot, and I get a
cryptic
"commlib error".

The ports 6444 and 6445 are excluded from the firewalls?
All machines get always the same address?
-- Reuti
Yes, all machines have stable IPs and they get the same address when
queried. All firewalls are disabled (they exist under the uni's
firewall), so that shouldn't be a problem. All machines also have
6444/6445 reserved for qmaster/execd, respectively.
Thanks for the help!
Cheers,
Drew

Otherwise, everything seems to be running fine. I've scrounged around and found
a couple
Mac Minis that I'd like to add to the mini-cluster, but I'd rather figure this
out
before adding them (and maybe shifting qmaster to one of them).
Any help would be greatly appreciated!
Cheers and best,
Drew
