Raw data

So here are are generating load for a JackRabbit test. A prospective partner wants to know what it can handle. Fair enough, we would like to know if we can push it to its limits.
Basic test: 4-way channel bond gigabit, with NFS export. 4 client machines mounting this, all generating load via iozone. Iozone run like this:

/root/iozone3_283/src/current/iozone -f /mnt/jr1l/dragonfly/iozone -n 16g -y 1g -g 16g -q 1g -Ra -b /mnt/jr1l/results/jrs-dragonfly.xls

Ok, that does it

After reading this

We should have know that dot-com wonderboy Mark Pincus was maturing when he sold Tribe, his social network for Burning Man attendees, to Cisco

at that bastion of high value reporting, Valleywag, I am henceforce going to borrow … er … steal … er … use Amir’s idea and call HPC what it really is. Social (and physical) networking for highly autistic AI Processing elements. Yeah, they are highly focused. On computing. And networking. Need a name for this.

Panta closes, LightSpace Technology put on ice

I had not written about this two weeks ago when I learned of it, but Panta Systems, a pioneer in flexible HPC and computing systems, closed its doors. Details are sketchy, basically they were unable to find a buyer is what I have heard. They were pursuing VC money about a year ago, though I am not sure what happened. Best guess, based upon conversations, was that they ran out of money. Seems to be a common refrain when dealing with/working with VCs.

More comments this weekend on SCO

It turns out that others, who know far more about the law than I do (I am not a lawyer, and don’t give legal advice) are suggesting that chapter 11 is less likely. They did a similar analysis, though with more legal detail. Worth the read.
The punchline is that someone may have advised them that this was a good idea, and that an external analysis seems to show that this plan was a very bad one for SCO. If SCO wanted to remain an independent, potentially viable organization, it should have stopped the lawsuits the moment it lost the decision on copyrights.

Saying it out loud

Ok, I need to ask this. Was the September 10th Barcelona launch, a paper launch? I can’t seem to find any in the channel. We have customers interested in them, and yes, I can get pricing. But delivery? Or delivery dates? Hmmmmmmmmmm….. AMD, please remember my suggestion for 8 core. It shouldn’t be hard. And … Read moreSaying it out loud

Some JackRabbit-S benchmarks

Have a new JackRabbit-S unit in the lab, 5.5TB (16 drive unit, 2 allocated for OS, 1 for hot spare, RAID6 built out of remaining 13 drives).
