Yes I am looking at ALL tasks in the Task manager.
----------------------------------------Thanks guys for all the input! Greatly appreciated. I will do some more tests to see what helps: Replacing the power supply and the RAM did not change anything. So, if it is a hardware problem, There are 3 options left: The CPU, the motherboard and the SSD. Of those 3 I can only imagine that the motherboard would be the culprit, so I'll replace it. But that is something for in the coming days. I'll keep you informed of this weird phenomenon. :-) Many thanks again; Carl Philip [Edit 1 times, last edit by Piri1974 at Apr 23, 2020 2:27:19 PM] |

Try a Linux Live USB. If it works fine there, it's not a hardware problem.
----------------------------------------Well, it wouldn't exclude the SSD as BOINC would run from the USB drive but I seriously doubt your SSD is at fault.  - AMD Ryzen 5 1600AF 6C/12T 3.2 GHz - 85W - AMD Ryzen 5 2500U 4C/8T 2.0 GHz - 28W - AMD Ryzen 7 7730U 8C/16T 3.0 GHz [Edit 1 times, last edit by Falconet at Apr 23, 2020 3:21:52 PM] |

Ok, so this week I have replaced the power supply, the motherboard and the RAM modules.
Still the same problem. :-( Then it must be the CPU, right? I cannot imagine it would be the SSD. I have purchased a new Athlon 200GE online and will receive it this week. So then I will replace the CPU, and see if the problem is solved. I'll keep you informed. Jeezz... |

Did you try the Linux USB?
----------------------------------------Or a Windows clean install? If RAM were the issue, you would have noticed it with computation errors and likely BSODs. SSD, makes no sense to me. Motherboard, again, you would have noticed it with system freezes and crashes, boot issues, etc. CPU, if it were faulty, computation errors and system freezes, etc. I still think it's a software issue but good luck. - AMD Ryzen 5 1600AF 6C/12T 3.2 GHz - 85W - AMD Ryzen 5 2500U 4C/8T 2.0 GHz - 28W - AMD Ryzen 7 7730U 8C/16T 3.0 GHz [Edit 1 times, last edit by Falconet at May 3, 2020 1:22:22 PM] |

Did you try the Linux USB? Or a Windows clean install? Hello; Yes I did a Windows clean install, twice, even once on a brand new SSD. Someone else gave me a good idea: Tomorrow I will test with work units from the Microbiome Immunity project to see if the problems persists with WUs from another project. Thanks for the input; Carl Philip |

Maybe try running MIP1 or ARP1 or HSTB and compare if the work units are about the same as before? You have a 1 year badge for MIP1 so maybe you can start there. I'm jealous your CPU runs so cool. Mine are in the 70's C on stock cooling. I need to install the Noctua air cooler that is still in the box before summer comes. Thanks, you have given me a good idea: Test with Microbiome Immunity WUs to see if the problem persists. Very good idea! I will do that tomorrow. Well, the fact that my CPU runs so cool is quite normal: The Athlon 200GE is a CPU with a TDP of only 35Watts. Someone else told me it could be a throttling problem due to overheating. So I replaced the stock cooler by a more potent AMD Wraith Max cooler. Consequence: Now the CPU runs even 5 degrees cooler: 35 degrees Celsius. In case you're not used to Celsius: That is cooler than our body temperature. :-) I guess 70 degrees is not really a problem, but I am very prudent and I don't like it when my CPUs get hotter than say 65 degrees. I also have an AMD FX8350, an 8-core cpu which is know for becoming quite hot. I put a cooler from Be Quiet! on it, and now even this CPU does not get any hotter than 55 degrees Celsius anymore. That is at 100% cpu load. So to give you some advice: Be Quiet! has very good coolers. I chose the "Dark Rock TF" cooler. TF Stands for Top Flow, meaning the fan blows downwards onto the CPU and the motherboard. This helps to cool the voltage regulator modules on the motherboard too. There are also sideways blowing coolers where the fan is mounted vertically and blows the hot air towards the exhaust fans at the back of the pc case. But I like these a little less as they blow no air at all onto the mobo. Here is the product link of the cooler I use: https://www.bequiet.com/en/cpucooler/572 This cooler can cool CPUs with a TDP value of up to 220 Watts. Their Dark Rock series of coolers are the best and most expensive. The Shadow Rock series is the series below that. And the Pure Rock series are the entry level coolers, which does not mean that they are bad of course. I love this brand, but, a little warning: Their coolers are not easy to mount and it is time consuming. But you can find enough movies on Youtube which explain. Thanks again for the input!

Okay, I have found some interesting things:
Someone advised me to switch to Micriobiome Immunity work units instead of the Mapping Cancer Marker WUs to see if the problem persists. I think not: With Microbiome I get run times between 2 and 3 hours. Does that look good to you? Is anyone else using a first gen Ryzen CPU to compare? Remember that the Athlon 200GE is a first generation Ryzen CPU, and it is also the cheapest and the slowest of them all: 2-core, 4 thread running at 3.2Ghz. This gave me another idea: It is the only CPU I have which has hyperthreading. I have turned it off, so now it is a 2-core, 2-thread CPU. I am running Mapping Cancer Markers WUs again to see if that solves the problem. And then I'll turn hyperthreading on again, and go up to 3 threads, but not 4. I know that hyperthreading makes run times rise somewhat, but what I had - up to 3 times longer - that is not normal right? I'll keep you posted. Carl Philip |

So 2-3 hours seems about right, based on my small sample. HT would certainly not cause such larger runtimes. I have never really tested but I've read runtime increases by 15% or something similar. - AMD Ryzen 5 1600AF 6C/12T 3.2 GHz - 85W - AMD Ryzen 5 2500U 4C/8T 2.0 GHz - 28W - AMD Ryzen 7 7730U 8C/16T 3.0 GHz [Edit 1 times, last edit by Falconet at May 10, 2020 9:03:54 PM] |

Many thanks for the data! In the meantime my pc has finished the first 2 WUs of MCM without hyperthreading: It does them in 1h45 to 2h15. I'll need to do some more WUs before I can conclude, but compared to the run times of 3h up to 7h WITH hyperthreading enabled, I think I have found the problem with the Sarcoma WUs combined with this Athlon 200GE CPU. Wow! |

Okay, I think we can conclude:
Problem identified, but not solved. Hyperthreading on this CPU leads to extremely bad and varying performance with the Sarcoma work units of Mapping Cancer Markers. The problem does not exist with Micriobiome Immunity work units, nor with the older lung cancer and ovarian cancer WUs of Mapping Cancer Markers. When I disable hyperthreading, I get very good run times of MCM Sarcoma between 1h37mins up to 2h07mins. When hyperthreading is ENABLED though, I get run times between 2h30mins up to 7 hours! So with hyperthreading disabled I actually get MORE WUs done per hour with this Athlon 200GE CPU than with HT enabled... Go figure. And this only happens with the Sarcoma work units. With the older lung cancer and ovarian cancer data sets I did NOT have this problem. What should I do now? Inform the people of the Mapping Cancer Markers team? I cannot solve this myself. :-( Thanks for all input folks. Really appreciate it. Carl Philip |
