Any results?

Any results?

 

I suppose "Multi-Directed Continuous Gravitational Wave search CV" will not be as impressive on the AMD Ryzen CPU due to reliance on AVX.

It will still do that project

It will still do that project since it does do AVX.  It just doesn't have the same AVX2 implementation as Intel.  Takes two registers and two clocks to assemble a AVX2 instruction compared to one and one for Intel.  Do we know that the Multi-Directed Continuous Gravitational Wave CV search app EVEN uses AVX2?  I would probably wait for real results using the chip before proclaiming it inferior to Intel for that project.

News today is that the current versions of Windows don't properly identity the Ryzen microarchitecture and are messing up big time with thread scheduling.  We will have to wait on Microsoft to provide the correct fix for Ryzen before proclaiming exactly where it stands once and for all compared to Intel CPU's.

Linux distros are already working fine with Ryzen with the latest kernels.

Computing some FGRPSSE on the R7 1700 @ 3.5GHz right now, should complete a bit after noon CET.

AMD is for hippies  Joking

AMD is for hippiesLaughing  Joking aside, it looks like a great chip.  Hopefully I'll have a reason to go back to using them.  Have not owned one since my 2500 Barton back in '03.

win10 scheduler cant

win10 scheduler cant currently recognize ryzen's cores/CCX properly . interestinlgly corenfo program shows its also true for amd apus

expect perf gains when/if MS will patch it.

 also make sure you have latest bios / chipset drivers in the coming months, vrery important for performance

22500-23000 seconds for the 693 credit FGRPSSE tasks, now testing 3.8GHz...

How many tasks are you running in parallel?

All 16 threads used, not exclusively Einstein though. Currently doing testing across multiple projects...

Remarkable.  I am running an i7-4770 (3.7 GHz) under Ubuntu 16.10.  Seven of the cores are on Einstein/Universe and one core supports a GTX 1060 on Folding.  I just started running the FGRPSSE as a test, and am getting about 29,400 seconds.  https://einsteinathome.org/host/12360156/tasks/valid

So the ratio is about 1.225, and the Ryzen has twice as many cores, so it can do 2.45 as much work.  I hope AMD does not run out of chips, they will be in high demand.

Edit: Do you have times for the Gravitational Wave search CV v1.00 (AVX)?  I normally do those on the CPU, and run the FGRP on a GPU.

Just out of curiosity I

Just out of curiosity I searched for "Ryzen" in the DB and here are the three other hosts that have this new CPU:

https://einsteinathome.org/host/12413792

https://einsteinathome.org/host/12502414

https://einsteinathome.org/host/12502620

Runtimes on windows seem to be between 27k and 38k seconds.
