To indulge, hit the Activity menu's 'Run Always'. That will certainly ignore any accidentally set selections such as time of day or use % or anything, just full out.

The BIOS/UEFI should have built-in MemTest or something or Diagnostics. Feel free to run that just to make sure there are no errors. I think there is an extended test that takes 30+ minutes.
----------------------------------------It's possible that there is nothing wrong at all. We can't really compare the sarcoma cancer MCM work units to the ovarian cancer MCM work units. 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.

We can't really compare the sarcoma cancer MCM work units to the ovarian cancer MCM work units. I can shed a little light on a comparison of the two. I have had a q6600 with 2gb memory running Windows Vista running exclusively MCM work units. On this machine the Sarcoma work units are consistently within a few minutes of 3.75 hours. If I remember correctly all of the ovarian units were consistently over 4 hours, more like 4.25 to 4.5 hours. Hope this helps a bit. Cheers

Armstrdj wrote the sarcoma were cut shorter also to accommodate the Android clients.

For info:
----------------------------------------As I said the time for each work unit on this PC varies wildly: From about 3 hours to almost 9 hours. This I think cannot be due to differences in WU sizes. This PC has an Athlon 200GE CPU. I have another PC with an AMD A8-9600 CPU: That one should be a lot slower, like 40%, but currently this one is a lot faster: It finishes work units consistently in about 2h45min, say 3 hours max. Could there be a problem with the voltage regulators on the motherboard? Can this cause a slowdown at full charge without making Windows become unstable? As I said Windows runs perfectly stable on the PC. I have already replaced the power supply with an old one I still had lying around, but this does not seem to change anything. So I can probably rule that out as the cause. Also, I ran the Windows 10 RAM test utility called mdsched.exe. This has found no problems. But I'll try to use another RAM module just to be sure. This is the weirdest PC problem I have ever had in my life... :-) [Edit 1 times, last edit by Piri1974 at Apr 22, 2020 4:37:56 PM] |

Based on your description, I would think that something is interfering with the science apps. Something is running at a higher priority than the science apps causing them to be interrupted. I base this on you saying that Windows is "snappy". Probably so, since it runs at a higher priority. Prior to Windows 10, the windows update task would start and run for days until it was cancelled. There may be some other task running as part of Windows that using the CPU instead of the science apps

Well, apart from the NVIDIA driver for the Geforce GT730 which I added, which I sometimes use for GPUGRID. But I never use MCM and GPUGRID at the same time, so they cannot interfere. And when I pauze BOINC and look in the Windows task manager, I see no other stuff eating resources, and the CPU usage effectively drops to 0... wel you know, almost. |

Hmm, would it be possible to boot up a live Linux USB drive, run some MCM work and see how the runtime compares?

Piri1974,
----------------------------------------if the machine should run boinc only, why do you stay on W10? You will make you life better and easier and you will improve your performances if you would switch to Linux. Cheers, Yves |

And when I pauze BOINC and look in the Windows task manager, I see no other stuff eating resources, and the CPU usage effectively drops to 0... wel you know, almost. Just an obvious question, are you looking at ALL tasks on the system in taskmgr and not just the ones running under your id? If so, there could possibly be a task that starts at times and runs for a period of time and then ends but does so many times a day. you might have to sort the taskmgr display by long term CPU usage and see if anything is above the science apps. If you find one, you could stop that service (assuming it isn't a critical system process) and see if your runtimes improve. One such task that comes to mind was the old indexing service that would kick off from time to time and use a significant amount of CPU time. Sorry, I can't be more specific as I don't use Windows anymore and don't have a machine in front of me to use as a guide. |
