Posted 1526 days ago by wiyosaya Thanks, Toni! 143,000 WUs as of today!! Awesome. Now I just need to get my BSOD problems resolved on my other computer, and I'll be totally back in action. |

New workunits
(Message 53110)
Posted 1613 days ago by wiyosaya I am getting high CPU/South bridge temps on one of my PCs with these latest work units. The PC is http://www.gpugrid.net/show_host_detail.php?hostid=160668 and the current work unit is http://www.gpugrid.net/workunit.php?wuid=16866756 Every WU since November 22, 2019 had been exhibiting high temperatures on this PC. The previous apps never exhibited this. In addition, I found the PC unresponsive this afternoon. I was able to reboot, however, this does not give me a warm fuzzy feeling about continuing to run GPUGrid on this PC. Anyone else seeing something similar or is there a solution for this? Thanks. |

Work Units????
(Message 48294)
Posted 2331 days ago by wiyosaya I use my PC as a heater during the winter and just started running again since it will be 45 tonight in Phoenix. Are there no work units to be downloaded? It keeps saying "communications deferred" and it says there is one work unit ready to download. Is there not enough work??? Personally, I find it amazing that these NO WORK WTF? posts continually pop up. So please excuse the following rant. For a user like us that donates computing power, it is easy to say to the project should "add whatever at whatever cost". However, the project has limited budget. If they had an unlimited budget, they would buy their own supercomputer and would not need us to supply computing power. The research field, such as what is done by this project - research - is rarely highly profitable. It is expensive to perform research, and this project has a donations button because they would love to have the extra money. Even if someone donates, it is a donation and the project will allocate any donation to what they determine will be the best place to spend that donation. Most research projects have a limited budget and can only do so much. I imagine that all BOINC projects have a very long wish list, and since they have a limited budget, they have prioritized their wish lists and will fill that wish list as they deem necessary and when the items are within their budget and priority. It is not the responsibility of any BOINC project to provide work units to any user for any reason. Not in the least. There are plenty of other GPU projects out there that have work to do such as Einstein, MilkyWay, Amicable Numbers, and Seti to name a few. Please take my advice: Join those projects and remember that we are the volunteers here; we volunteer our computing power to run the work units of BOINC projects. Not all projects will have work units at all times for any number of reasons whether we like it or not. If that is not acceptable, then I suggest not running BOINC. Again, please excuse my rant. |

Posted 2355 days ago by wiyosaya Would FPGAs ever be used in a project like this or are GPUs still faster? The thing about an FPGA is that they are primarily used in low-volume production situations or for low-volume specialized applications. They would require specialized programming, and, in the case of a project like this, the people like you and I who run this project would need to have one, or a board that contains one, in their computer in order to run the project. Contrast this against a GPU or a CPU where GPUs and CPUs are commonly available. Virtually everyone who has a computer has a CPU and a GPU inside the computer, although, some GPUs are not acceptable to this project. What makes the GPU/CPU aspect of BOINC attractive to a project like this is that virtually no one has to spend extra money on a specialized board to put in their computer to run the project. If we did have to have a specialized board, outside of the GPU requirements of the project, I doubt that there would be as many people that run this project because the chances are that it would be significantly more expensive for the average computer user to run this, or any project, that required a specialized FPGA device. This is not to say that a project like this could not be run on an FPGA. It could. However, at least as I see it, the project would constrict itself significantly, and might get very few people who would run it. To sum it up: GPU/CPU = widely available, virtually every computer has at least one GPU/CPU - requires no specialized hardware, requires little end-user knowledge. FPGA = limited availability, project runners would have to spend extra money to buy one, requires specialized programming knowledge that the project would have to support, may require that the project runner (you and I) have specialized knowledge. |

CPU Projects

Posted 2358 days ago by wiyosaya The latest generation of Intel server CPUs have 28 cores, and you can put 8 such CPUs in a single server (however it costs $13000 each). The latest AMD server CPUs have 32 cores each. I do not think there is a limit to the number that can be put on a motherboard, but AFAIK, current MBs only support two. They cost $3,000 each. CPUs are better at iterative (serial) tasks where the input for the next iteration is the output of the previous iteration such as an integration that might be used to calculate a path to the Moon. GPUs are better at tasks that have multiple sets of data where each data set requires the same calculations. Both AMD and Intel CPUs have special functions commonly termed "SIMD" for "Single Instruction Multiple Data" (MMX (IIRC) and successive generations) where they are capable of performing the same instruction on multiple sets of data like GPUs do. Each has their place, as I see it, and I have also heard that there are BOINC projects out there where both GPU and CPU applications exist and they both take the same amount of time to run. I program and maintain an FEA application professionally. Only portions of that application can be done in parallel. It is not as easy a task as one might think to compute large amounts of data in parallel. For the application I work with, it is basically not possible to program the solver portion as a massively parallel portion of the code because each successive step requires the output from the previous step as input. The exception in that part of the code is that once Gaussian elimination is done, back-substitution can be done in parallel. The post-processor portion of the code is a different story. Multiple load cases can run in parallel - where the input for the post-processor is the output from the solver step. |

An important note for Windows XP users
(Message 47907)
Posted 2408 days ago by wiyosaya Regarding the recent WannaCrypt attacks, Microsoft has released a vulnerability patch for older operating systems as well.Sorry for the much belated reply to this... Another way to block wanacry is to block netbios ports, both incoming from the internet and outgoing to the internet on a firewall. There is no reason to have those ports open anyway. I have had those ports blocked to/from the internet for well over ten years, and I have not noticed any issues from having them blocked. The fact that I had them blocked may have prevented problems. I am on the side of retiring the app for XP, and it seems that the project has decided that due to the fact that so few users are running XP at this point. As a software engineer, I agree with this. The company that I worked for dropped XP support a few years back. XP simply will not run software developed with the latest compilers, and supporting such machines becomes a nightmare scenario I personally have an XP x64 box, but there are no longer even Windows Defender updates for it. It is a dual core Opteron machine on which I ran this project; however, these days, it consumes a lot of power in comparison to newer machines for far less computational power even if I did put a newer GPU in it. If people still want to run a machine like that and they have the technical knowledge to do so, I suggest wiping the machine and installing a Linux variant - or if the budget allows, buy an OEM version of 7 or 8.1 or, perhaps, 10 (assuming 10 still supports the hardware) and install that. However, with aged hardware, Linux would be a better choice, IMO. |

Posted 2416 days ago by wiyosaya speaking of...but still mostly x1 slots: Marketing! :( As for Threadripper, I have seen MBs where all x16 slots are not electrically x16 slots. It looks like the MSI has 4, electrically x16 slots, however, it would be worth an e-mail to them if one were going to buy this board to ensure that they are all x16 slots. https://www.msi.com/Motherboard/X399-GAMING-PRO-CARBON-AC There is an EPYC proc that is about the same price as the 1950X, however, the MBs out there as of now do not look like they would be good choices in which to run 8 gpus - IMO. |
