What cpu's are in both systems ? Cheers Linux: 2 x Xeon X5660 @ 2.8GHz, 12 physical cores, 12 cores running WCG 24/7 Win10: 1 x Ryzen 7 2700 @ 3.4GHz, 8 cores/16 threads, 12 threads running WCG 24/7 Linux workstation has 64GB of DDR3 Win10 workstation has 32GB of DDR4 I can upload a list of completed OP jobs with MachineType and RunTime if that helps address the potential difference in WUs question.

A quick question. Assuming this doesn't support mac, just windows etc. OPN1 doesn't appear in my list. Everything else I'm running seems to work.
Anyone know for sure? |

Macromancer Xeon X5660 Passmark score 6,216 Ryzen 7 2700E Passmark score 14,647 The Xeon is from 2010 and the Ryzen 7 is from 2019, a much more recent chip. It has a Passmark score more than twice as high as the Xeon (higher is better.) The Ryzen 7 should be beating the pants off the Xeon. So, if the Windows system is slower, I would say it is the OS. You could try to swap the installs and then compare. That would be better test. Cheers Edit: Is there a reason you are not using HT on the Xeon ?

HT with these old Xeon X5660 CPUs is crazy slow and generates a ton of heat. I suspect the Spectre and Meltdown patches really nerf the HT on these older Intel CPUs. It's an old HPZ800 with OEM fans. In a few months I'll try Linux with the Ryzen CPUs. I'm waiting for the B550 mini-ITX motherboards to become available before I upgrade a Win10 PC and recycle some older parts into a new Linux build.

I am finding the AutoDock packages much better for one of my systems. A Older AMD based system running Ubuntu 20.04 would just lock up when running the Africa Rainfall with a AMD FX9590 processor got so bad I had to swap it out for the older AMD PhenomII X4 955 Processor to keep it stable no other changes just a CPU swap. Thought it might be overheating but the CPU was running at 48 degrees as had all cores running 24/7 at 100%.
Have swapped back to the AMD FX9590 now I have dedicated all systems to the Covid-19 project and it is so far behaving as the FX9590 is about 150% faster than the Phenom. |

Because of a poor Internet connection at home, I do limit the number of ARP WUs. However I use to run (if enough ARP WUs are available) 3 ARP WUs simultaneously on the old Phenom II x6 machines under Linux/Ubuntu without noticeable performance problems.
----------------------------------------In comparison, MIP1 is significantly negatively impacting the performance as soon as more than 2 MIP1 WUs run simultaneously. Cheers, Yves |

HT with these old Xeon X5660 CPUs is crazy slow and generates a ton of heat. I suspect the Spectre and Meltdown patches really nerf the HT on these older Intel CPUs. It's an old HPZ800 with OEM fans. I have a variety of the X56xx series (x5670, X5650, X5649) on Dell and HP servers. I do run them all with HT as I figure I get greater throughput that way with 24 threads apiece running. They run the OPN1 units in 3.5 to 4.5 hours, so I don't think that is too bad. Maybe sometime I will try one of them with the HT turned off and see how that affects output. All are running Linux. They do produce heat, I agree with that, but I have them in a shed where I have my baby chicks, so I have a use for the excess heat right now, and they don't mind the fan noise. I certainly would not recommend them for small spaces or indoor house use. My I7-3770 Windows 7 runs them in about 3 to 3.25 hours and a Q6600 Windows Vista runs them in about 3.5 to 4 hours. Hard to say if there is any difference attributable to OS at this point. Cheers

They run the OPN1 units in 3.5 to 4.5 hours, so I don't think that is too bad. Cheers Thanks for the info, SgtJoe. With HT off on the X5660 CPUs, I'm getting 2.3hrs per OPN1 job and CPU temps of 76C on average. With 12 threads/12 cores, I'm cranking out 123 WUs a day. Assuming 3.5hrs as a best case with HT on, I'd get 164 per day, about 34% more throughput for a lot more heat and electricity. The older Xeon CPU based workstations and servers are ubiquitous with low upfront cost, but I'm not sure they make sense on a TCO basis as they uses at least 2x the electricity and produce a lot more heat than my Ryzen based systems for the same amount of throughput.

I only noticed that on my particular Windows 10 system with a Pentium G2030 (2 cores at 3GHz) the claimed credit per WU was quite low and then the wingman got more credit and it averaged out in my favor. The WU's actually got done in under 3 hours but the estimated time in the beginning was always close to 8. So I switched to Linux on a VM on the same hardware and now the estimated time is closer to 3 hours which is also closer to the actual runtime.
