Thank you for that Christmas surprise.
And Cluster-Zen's performance on cgos is impressive, indeed:

With gigabit ethernet my humble opinion is that you should have no problem.
But, testing what happens if you "artificially" canc

No (unless I misunderstood what you mean, sorry in that case!)

Hi Hideki,
Is that difference due to a scaling limit of Zen, or is this due to the
cluster overhead? Would moving from gigabit to infiniband
Hi Nick,
I'll perticipate comming tournaments as much as possible but it's
still under development and needs much more work and time for full
performance.
Since my mini cluster uses usual Gigabit Ether, which is much slower
than expensive Infiniband or such high speed network devices, it

It is: Let the cluster also run on KGS - against the humans.
I'd like to do so but it's not allowed to connect

Hmm. As CGOS is also Internet, it seems that Zen-author
