Anyone do any work with coprocessing HP machines of any kind?

Hello John,
is an HP Z400 workstation the kind of "coprocessing machine" you're talking of?
Hope this helps. ▼

Yes that is what I was talking about. How doe that work with your P? THANKS! ▼

No just heard of this before. Was wondering who used it & how it was used. JK ▼

They are nice enough machines, but there's nothing magic or special about them. They're standard Xeon workstation computers running ECC memory and Windows 7. ▼

The Z820 line now has some dual 8 core Xeon ( E5 Sandy Bridge ) processor options. If that is not enough, there are also some pretty amazing GPU coprocessors which can make some parallel computing tasks such as FDTD a lot more practical if the model can be split into many small elements.
e.g. Such software can use either a high end graphics card or something like the Nvidia Tesla GPU which gives you 484 cores and claims 515 Gflops
I've been looking as I think I can now justify such a beast at work - fingers crossed. Edited: 17 May 2012, 1:36 a.m.

Quote: I'm not getting it, either. What's "coprocessor" about this machine? It just looks like a standard Intel quad-core processor box, to me. Nothing special, architecturally speaking. I suppose you could trick it out with multiple nVidia GPU's, but then, you can do that with any white-box machine. Best,

For nice HP coprocessor, try an HP98635 floating point math card for HP9000 series 200, it can speed up basic x3 and pascal x7 :) I don't have this machine (I regret it ...) but you can try this Emulator Olivier
P.S. it's not a real HP hardware, it use a national 16081 fpu, 68881 were not widely available at this time :) Edited: 17 May 2012, 11:26 a.m. ▼

Hey, you want to see a sexy HP workstation, go look at the HP Z1. I saw one open at NAB in the HP booth. It's got a full graphics card yet it's like a large iMac with everything behind the screen. You can open it up and have full access to all the hardware unlike the iMac. We also use a couple of dozen Z800s for Harris Velocity hardware platforms. They are great machines. Gerry ▼

Nothing new, as integrated system, I make my phd on a sparcstation ELC :) For nice hardware try a SGI Octane: Weight a ton, had one of the best audio subsystem I know and best of all don't have a bus for ultimate performances (use gold platted press-contacts for IO) But its old hardware ...
