Posted 19 Mar 2022 by ProDigit Post: Just wait for intel Arc GPUs to come out. They're meant for Bitcoin mining, and a whole plethora of other 64bit applications. Granted, they're not as fast as a 3090; much closer to a 1060/2060, but are much cheaper and only consume 80Watts presumably. Not released yet, no actual specs, but the laptop GPUs come out first, as Intel will gain experience, and release the desktop versions later. More news on March 30 according to: https://www.techradar.com/news/pc-gamers-rejoice-we-finally-have-a-launch-date-for-the-intel-arc-gpu |

advanced/improved usage (SD card, RPC)
(Message 107495)
Posted 19 Mar 2022 by ProDigit Post: Boinc on SD card is not recommended, as SD cards have a notoriously low error correction, slow transfer speeds, and low life cycle. You'd be better off running Boinc off of a USB stick, than an SD card. The ONLY SD cards I know of that have a better ECC, is Sandisk A1 and Sandisk A2 microSD cards. They're probably the only ones that can handle at least an OS, much less a hundreds to thousands of MBs of data read and written to per day. |

Can't get BOINC to use all my resources
(Message 107494)
Posted 19 Mar 2022 by ProDigit Post: If you use the android manager, you can set the active CPU to like 90%. That way, the CPU isn't interrupted, thinking you need CPU resources. Most Android systems only use the E-Cores for processing WUs, since the performance cores always give trouble with mobile devices (overheating, and battery issues). If you can, try to download and install a Linux OS on this device. It's much better in allocating resources, if you can find a compatible image for your system, or you'll have to build an image yourself (oftentimes the best solution). Or, perhaps there's a kubernete that can run. |

Posted 15 Mar 2022 by ProDigit Post: Glory is crunching GWs 24/7 on 3 GPUs over at Einstein I'm running 5 out of 6 threads on Einstein GW. One thread is MLC. MLC is actually more demanding (sometimes requiring well over 2GB per WU of RAM, most of the time using 1,2GB of RAM), than GW. GW reserves 14GB, but only uses 500 megs to 1,5 Gigs, averaging around 800Megs per WU (or thread). I run 2 GPUs, RTX 2070 and 2060. The 2070 is significantly faster than the 2060 doing 3 threads per GPU. |

Posted 12 Mar 2022 by ProDigit Post: If your VRAM is bad, you shouldn't use OpenCL or Cuda calculations on the GPU, as many projects store results in the VRAM, to be reloaded and reprocessed again. The GPU is good enough for display output, even with bad VRAM. I would however, check if each VRAM module has a cooling pad installed. Many GPUs came from the factory without, and VRAM overheating (especially when overclocking) caused lots of glitches. Removing the heat sink will allow you to refresh the thermal paste on the GPU. So it's not going to affect your CPU jobs, but I would recommend to use the GPU as the primary GPU in your system for display out only, and have a secondary GPU for crunching data. Works well if you have 2x full size slots at x8 speeds. Or, install it as a secondary GPU, but use it as a display out, and use the primary GPU to crunch data on, if your secondary slot is limited to x4 speeds or less. |

Einstein@Home not using 100% of graphics card
(Message 107326)
Posted 9 Mar 2022 by ProDigit Post: Einstein hardly ever does a modern GPU at full load. The WUs are more made for 1030 GPUs than any more modern ones. Even with 3 to 5 WUs per GPU, I still only get it up to about 75%. If you have a laptop with an Intel IGP and shared with an Nvidia GPU, you might run into issues. However, if each GPU runs their own WUs, you can increase GPU usage on Einstein by running 2 or 3 WUs at the same time. |

Recommended max temperature for Boinc on Android phone

Posted 6 Mar 2022 by ProDigit Post: I bought a Samsung Galaxy A71 with the specific purpose that it could do 6 threads at a time. Unfortunately, after a Boinc and system update, I can now only do 4 threads, and even then it overheats (regularly has to throttle down). |

Recommended max temperature for Boinc on Android phone
(Message 107279)
Posted 5 Mar 2022 by ProDigit Post: So, 2 of my phones had their batteries expand after crunching WUs with a 40C max temp. The temperature really depends on how far the battery is from the CPU, and if the CPU cools via the screen and back panel, or only the screen (and have a plastic back plate). On my Samsung Galaxy phones, I've lowered my max temp to 38C, but it still feels quite hot; so I personally would recommend anyone who is crunching data on their phones, to set 37C as the max battery temperature to crunch data on. 35C being a lot safer of a margin. If your phone is in a colder environment, you could go a degree or two higher on the temps, but anyone who has their phones in an ambient temperature of 70F or higher, should preferably keep the battery temperature below 37C; 35C if you're in 80-85F ambient, and ~30C if ambient temperatures exceed 90F, or the phone is in direct sunlight (not recommended). |

Posted 28 Feb 2022 by ProDigit Post: All of my systems have and always have had coolbits enabled and are overclocked with custom fan speeds and power limits. That’s not the issue. I also run the normal desktop version of Ubuntu. Not headless. I guess whenever I happen to have a spare minute, which is more rare than spotting a unicorn, I'll have to take a look. |

(Message 107211)
Posted 27 Feb 2022 by ProDigit Post: I have two systems running right now with 7 GPUs and 5 GPUs respectively. The issue is when you try to enable cool-bits for overclocking and lowering TDP. That's when the desktop on 20.04 started crashing. 18.04 does it with issues, I mean, the desktop still has issues. But at least I can fold now while setting TDP and GPU core clock values, as well as manually adjust fan speeds, etc... If you just run it stock, you won't have any issues running multi units. Perhaps if you run it without a GUI, just the headless (terminal) version, it might work fine, but I need the auto network configuration that comes with the GUI. Don't want to manually have to install and enable the networks. Too many frustrating experiences with that. |

Posted 27 Feb 2022 by ProDigit Post: One of the reasons I stopped updating my systems, and disable auto update. In fact, most of my systems still run a 2 year old OS, no security updates, no kernel updates, no manager updates. It runs strong, and I'll only update it, when my units go offline. |

Posted 22 Feb 2022 by ProDigit Post: I've noticed that my little portable PC, equipped with Dual RTX GPUs, has been running pretty stable under linux lately! I've upgraded to the latest version of Lubuntu 18.04.06 While no longer officially supported, this is the last version that I could run with Dual GPUs without any issues. Newer Linux versions gave a lot more problems trying to get 2 GPUs to run in CUDA/OpenCL. Though, if you're running a single 3080 or 3090 from a cheap dual core CPU like a Celeron, you probably could outperform two older GPUs in terms of performance and/or PPD. Thus, in most scenarios, you won't need to run 2 GPUs, and a newer linux is fine. I know Intel CPUs usually run more stable than AMD CPUs, though I was used to seeing at least once a week my system down, or in need of a reboot. Still, I've been amazed how my 3 year old Celeron, with RTX 2070 and 2060 GPUs, has been running for weeks without any downtime! |

Posted 17 Feb 2022 by ProDigit Post: A piece of advise, If you run WUs on your smartphone normally (without a fan), it's probably better to lower the temperature to 38C. Mine throttled at 39.5C and after 1,5 years, the battery expanded all within a few hours! |

Posted 17 Feb 2022 by ProDigit Post: OK, yoyo, Einstein, and moo and universe all seem to want to send me tasks, While one phone is working, the other, I get a message saying "transfers suspended". Playing around with the settings and it works now. Overlay? Or perhaps force stopping and starting it again did it. Moo! And Yoyo give me computation errors. LHC seems to never have any WUs. Einstein still hasn't sent a WU. Rosetta is still running the cpu very hot. It's not recommended to run more than 2 WUs per 4 cores, and I haven't yet found a way to adjust max wu per project on android. If I adjust the setting in the website, it'll also affect the setting in my desktop versions. Universe is about the only thing that still runs properly on Android 10/11 right now (will see how Einstein does). |

(Message 107130)
Posted 17 Feb 2022 by ProDigit Post: Ok, I may have found an issue on my end. Boinc isn't installed from Google Play, so it doesn't automatically update. I'm still running version 7.4.53, while there's a much newer version out (7.18.1). I installed the update, and reloaded the projects. It seems like most of my project account login issues had to do with using the too old version of Boinc. Universe@home is the first one to send me WUs. On the old client, Einstein did send WUs, but they would be aborted, or processed for like 1% or less before erroring out. I'll update if I see anything more. |

Posted 17 Feb 2022 by ProDigit Post: WCG has temporarily halted WUs, and I'm looking for more projects to run on my Android 10/11 phone. With WGC down, - Einstein not giving out ARM WUs (at least on this version), - and Rosetta stopped it, due to high CPU temperatures on mobile devices, - Moo Wrapper! doesn't seem to recognize my account on android 10/11, - PrimeGrid stopped supplying WUs for android systems a while ago, - Project Asteroids seems to be down still - Universe was up again recently, but for Android 10/11, I still can't log into my account. - Yoyo recently restarted after an outage, but apparently not for Android 10/11. Any other projects that support Android 10/11/12 phones ? |

(Message 107114)
Posted 17 Feb 2022 by ProDigit Post: yeah, make sure the amount of cores assigned to the VM are 99% or lower (leave 1 cpu thread for OS operation). Like above said, it could be either: 1- The VM is configured to run fewer cores/threads than what you actually have, and thus the software can only access those, 2- Boinc is assigned only a few cores (eg: 33% of CPU resources) 3- Not enough ram is allocated in the VM to run that many WUs, or the RAM the WUs need to run, exceeds your actual RAM. 4- Either on the project's website, or in app_config of the project, a limitation is set to the # of CPU threads per WU type. |
