Hello,
The question as in header, I can get a Phi7120 cheaply.
Is it making any sens anyway, or better get more classic GPUs?
Regards,
Peter

Nope. BOINC has no provisions for that kind of device as far as I’m aware.

Seti@Home classic workunits: 29,492 CPU time: 134,419 hours

Thanks for confirming what I thought,

Considerig this: https://www.servethehome.com/intel-xeon-phi-x200-knights-landing-boots-windows/
Boinc could run 256 of S@H tasks, well @1,3GHz would go slooooow.

One I can get is 7120 is former generation and even if somehow I could manage it, I presume energy costs per FLOP makes no sense.

Even if you got it recognized as 256 CPU cores, you still wouldn’t be able to run 256 concurrent jobs at SETI since the project here limits you to holding only 150 at a time.

It's obsolete these days.

Only 16G ram, 61 cores @ 1.2Ghz!

I think a 3700X is faster than that Phi board. 16 * 3800Mhz is around 60000 Mhz roughly the same and then you've got FPU enhancements and it's pipeline.

Obviously, after looking @ top machines setup, here at S@H the only conclusion is linux + nvidia.

Exactly, most bang 4 buck = Nvidia 1660TI or Super. Uefi Motherboard is required because all those new GPUs require UEFI support in bios to get detected properly.

Thank's for info on uefi. Is my current Lenovo C30 double Xeon v2 machine suitable for them?
Another question is, if my current Quadro P2000 GPUs would work better under linux?
If so I think I will convert this host to linux.
I found info of End of life for Intel Phi products, so that's why prices are diving.
Anyway it would be an intersting experiment to run Boinc on Phi 72xx Knights Landing which suport AVX512.
Ommm.. BTW is S@H code using AVX2 or AVX512?

Many have tried to get those things working here since they were 1st introduced, but none have succeeded.

Cheers.

SETI does not take advantage of AVX2 or AVX512. An AVX2 app exists, but it’s just the same code recompiled for AVX2. It doesn’t run any faster than the AVX app.

Your nvidia cards will run better on Linux providing that you use the Special CUDA application. No problem with Xeon E5 v2 chips. That’s what I like to use.

Good news, Thanks!
But I'm still realy amazed that Phi could not be harnessed for Seti… of cource it's energy inefficient regarding todays hardware achivements but theoreticly schould work as shown in the link I've cited previously, Cinebanch run on Phi just right off the box.

For what it seems there seems to be a UEFI bios, but not fully compliant. Could work though.
Quadro P2000 seems to be a Cuda 6.1 so it would work better in Linux. Run TBars all_in_one package aswell and your system should fly!
