With all due respect, rgb, you're somewhat out of date with respect to
(Open)Solaris. I don't think anyone would argue that Solaris x86 wasn't a
mess prior to Solaris 10. However, it took a massive step forward in Solaris
10 once Sun really started pumping out Opteron servers. Additionally, it's
I've got a zx2000 (1.5 GHZ/6 MB Madison processor, 2 GB PC2100 RAM, general
system details at http://www.openpa.net/systems/hp_zx2000.html) that I use
for testing and benchmarking. Obviously there some difference in performance
characteristics between this machine and a gazillion-processor Altix

Interesting thing is that this presumably 5400rpm drives outperforms
its 7200rpm counterparts. And it's green too. :)
It isn't a 5400rpm driver, it is multispeed with speed between 5400 and
7200rpm.
Actually, it almost certainly is 5400 RPM. WD's website originally

I was recently surprised to learn that SSD prices are down in the
$2-$3 per gbyte range. I did a survey of one brand (OCZ) at NexTag
and it was:
256 gigs = $700
128 gigs = 300
64 gigs = 180
32 gigs = 70
Alas, these drives have lousy random write performance. As in 4 IOp

yeah - the point seems to be that we (still) need to scale memory
along with core count. not just memory bandwidth but also concurrency

offhand, I'd guess that adaptive grids will be substantially harder
to run efficiently on a GPU than a uniform grid.
One key thing is that unstructured grid codes don't work as well.
The problem is the indirect addressing.
Bingo. GPUs are still GPUs, and are still heavily o

Get a USB stick that boots into Linux. Set up one machine the way you want,
then boot it up using the USB stick. Do:

Hello all,
I've recently ended up with a complete QsNet interconnect setup - a fully
loaded QM-S128 with 126 QM-400 cards and associated cables. Now, I'm
obviously not going to be using all of this. I don't have 16 computers to
cluster, let alone 126, and the 700W power consumption of the swit
