G'day Gary and all Have a squizz at GADGET2: http://www.mpa-garching.mpg.de/gadget/ I used to run it for Local Group galaxy dynamics sims. Of course most of the 'fun' was setting up the initial conditions :) Cheers Steve ___ Beowulf mailing list, Beo

G'day all With my astronomy hat on... Of course what works in your favour for Earth imaging is that you're not struggling to grab photons. Looking up instead of down means your limited by the Reynolds number. On near-perfect conditions I think Keck can at best get about 200mm of clear air. This

G'day Jim and all Pushing further from the topic (given your day job Jim ;) Also freely accepting this is pure speculation... 30% efficiency on the solar cells?! A generous round up I suspect? I thought Deep Space 1 only got ~23%? And that was the soopa doopa focus layer, no dust out there to spe

[Beowulf] Minimum cable length

2006-03-22 Thread steve_heaton
Dear Great Minds Not strictly a Beowulf question but I suspect knowledge on the topic lurks herein. I can't seem to find a straight answer on the "real" *minimum* cable length for gigabit ethernet. I'm looking to make things on my new toy nice and tidy. Assume Cat5e/Cat6 cable, Intel e1000 NIC
