2) Message boards : News : Discord channel for GPUGRID (Message 61333) Posted 26 Feb 2024 by Richard Mitnick Post: Why should I take on something new when the project has sent me no work? Is there a problem with my computer. I am only recently back to BOINC after years away. In my previous adventure with GPUGRID I amassed 17,000,000 credits. That was on a much different machine but the current machine should be good. Why have I not received any tasks? I would like that answered before I try something new. Thanks.
3) Message boards : Number crunching : Why no work on my computer (Message 61317) Posted 21 Feb 2024 by Richard Mitnick Post: Why have I not received any work on my computer. Is there something wrong with my computer, something the project does not like? The computer is performing well on seven other projects. Thanks

5) Message boards : Number crunching : Why no work (Message 60885) Posted 4 Dec 2023 by Richard Mitnick Post: Why no work? IS my NVidia T1000 GPU not up to your standards? If, so, tell me and I will detach from the project. Thanks.
6) Message boards : Graphics cards (GPUs) : New user checking on my drivers (Message 60872) Posted 14 Nov 2023 by Richard Mitnick Post: My machine has Intel onboard compliant with nVidia T1000. Will that work?
7) Message boards : GPUGRID CAFE : GPUGrid and social media (Message 44134) Posted 11 Aug 2016 by Richard Mitnick Post: I see that GPUGrid has a Facebook page, but very little posted. I also see RSS on forums, but I could not find RSS for the project. GPUgrid is a very important project, but the project needs to get its word out to be more prosperous. Social media is what every major scientific institution and university is using to do this.
8) Message boards : Graphics cards (GPUs) : Shot through the heart by GPUGrid on ATI (Message 28216) Posted 26 Jan 2013 by Richard Mitnick Post: After reading through all of this, it seems to me that there should be somewhere on the web site a statement of the minimum requirements to safely and successfully run WU's on this project. Specifically, cards, power supply, CPU, DRAM, maybe cooling. As I revealed, I have a very expensive and powerful computer which managed to work up 17 million credits, but which had to be rebuilt three times. That is a very costly situation, definitely to be avoided if possible.
9) Message boards : Graphics cards (GPUs) : Shot through the heart by GPUGrid on ATI (Message 28185) Posted 24 Jan 2013 by Richard Mitnick Post: MrS- Thanks for taking so much time to look at my issues. The i7-920 machine will go into the shop to have the CPU looked at. Either new thermal paste will be done, or if necessary and if possible a replacement, unless the cost is too high. Also, I will ask about better cooling. Regarding Dagorath, he is just a nasty harsh mean-spirited Canuck who should move to Florida. He does not even like Hockey. TJ- Very interesting about the power supply. The Shift Super Stock has a 1000 watt unit. skgiven- Thanks also for your comments. I have to say, I went into GPU crunching with very little knowledge, looking especially for the GPUGrid project. I am surprised I have gotten this far with GPU work. GPUGrid is very demanding; Milky Way requires DP cards, yet ATI is not all that popular. This field is still in its infancy.
10) Message boards : Graphics cards (GPUs) : Shot through the heart by GPUGrid on ATI (Message 28145) Posted 23 Jan 2013 by Richard Mitnick Post: flashawk- We actually ran it both ways. In fact, with GPUGrid in the mix, we ran SLI, we ran two cards, we ran BOINC on Dev 0 only, Dev 1 only, we really tried everything, through two builds actually, and had a lot of success which was in both cases only temporary. The only thing that was not done was to connect the monitor to Dev 1. The builder was adamant that monitor be on Dev 0. The first build ran successfully for about ninety days, the second build for about 60 days, both running GPUGrid, each with SLI enabled and this disabled. The worst was SLI disabled and BOINC ignoring Dev 1, so that both BOINC and the rest of the computer were using Dev 0. I am sure that I said earlier, I was told that BOINC wants to be on Dev 0. The way it looks now, I am not going to change anything on the Shift Super Stock. Of course, as soon as I post this, I may eat my words. But, up until now, with SLI enabled, and thus running BOINC and the rest of the machine on what looks like Dev 0, running SETI and Einstein GPU WU's, plus a bunch of CPU only projects, everything is stable. And, this machine does nothing else. It was purchased with the express intent of running BOINC projects but with a focus on GPU work. My colleague has done the same thing, a Maingear F131 that all it does is crunch (that is an older style F131, the case is more standard and so GPU work can be questionable. Also, my colleague only runs WCG and he is on the WCG build of BOINC 6.10.58, still the standard at WCG). You know, we are talking about a lot of money devoted to this work. If I can get some good advice on what to put on the F131, then I will run GPUGrid on that machine. If not, then I will run Einstein, SETI, and a bunch of CPU only projects. One way or the other, the machine will be purchased. It will replace my oldest desktop, an i7-920 that is about 3-1/2 years old. It is apparently now accepted as a fact that i7's run hot. The topic is not new, but it has only recently been dealt with in any meaningful way with tthrottle to control temperature. This i7-920 ran BOINC at 100%/100% for along time with temperatures in the 90's C. Now, we know that is abusive. All of my machines are now controlled for CPU with tthrottle. So, this CPU is old before its time. There is work which is failing to finish, runt times that are ridiculous. I could have the CPU changed out, but it's like a car: what might be next. I want to get this settled very soon. I can still get Win 7; but I do not know how much longer that will be possible.
11) Message boards : Graphics cards (GPUs) : Shot through the heart by GPUGrid on ATI (Message 28140) Posted 23 Jan 2013 by Richard Mitnick Post: So, I guess what I would request is, what would be considered good Nvidia cards to put on a new machine, and what in the way of specifications for a power supply? Here is what the Maingear F131 Super Stock would have Intel® Core™ i7 3930K Six-core 3.2GHz/3.8GHz Turbo 12MB L3 Cache w/ HyperThreading. MAINGEAR EPIC 120 Supercooler (CPU cooling)- but that looks like a water cooled system and I have had bad luck with that, so I would ask for air cooling similar to what I have on the Shift Super Stock. Intel® Turbo Boost Advanced Automatic Overclocking 16GB Corsair® Dominator™ Platinum DDR3-1600 Extremely Low Latency 1.5V (4x4GB). The choices of Nvidia cards are way too plentiful 2x EVGA® GeForce™ GTX 680 SuperClocked 4GB Total GDDR5 In SLI w/PhysX [ENTHUSIAST - OC] 2x EVGA® GeForce™ GTX 680 FTW+ 8GB Total GDDR5 in SLI w/PhysX [ENTHUSIAST] 2x NVIDIA® GeForce™ GTX 680 4GB Total GDDR5 in SLI w/PhysX [ENTHUSIAST] 2x EVGA® GeForce™ GTX 670 8GB Total GDDR5 in SLI w/PhysX [ENTHUSIAST] 2x NVIDIA® GeForce™ GTX 670 4GB Total GDDR5 in SLI w/PhysX [ENTHUSIAST] 2x MSI® GeForce™ GTX 660 Ti Power Edition 4GB Total GDDR5 in SLI w/PhysX [ENTHUSIAST] 2x NVIDIA® GeForce™ GTX 660 Ti 4GB Total GDDR5 in SLI w/PhysX [ENTHUSIAST] 2x NVIDIA® GeForce™ GTX 660 4GB Total GDDR5 in SLI w/PhysX [ENTHUSIAST] The SLI can be disabled, but since BOINC wants device 0 and Maingear wants device 0, I have SLI enabled on the Shift Super Stock. If either was O.K. with device 1, then I would not be doing this. 1TB Western Digital VelociRaptor SATA 6G 10,000rpm 64MB Cache This was actually the last change made on the Shift Super Stock. This is alleged to be an "enterprise grade" (whatever that means) hard drive normally used in servers. Power supplies available are 850 Watt Corsair® AX850 80+ Gold Certified Modular Power Supply ROHS 660 Watt Seasonic® X-660 80+ Gold Certified Modular Power Supply ROHS So, this is a lot to ask, but I find people here really know their stuff. Any opinions, and I know they could only be seen as opinions, will be gladly received. I am not about the business of building any machine myself. I am only about the business of paying for what works. Thanks in advance for any and all replies.
12) Message boards : Graphics cards (GPUs) : Shot through the heart by GPUGrid on ATI (Message 28132) Posted 22 Jan 2013 by Richard Mitnick Post: MrS Thanks. I did run HW Monitor for a while. It never showed anything untoward regarding GPU temps. My power supply never failed, I was always able to get something to happen on failures, even if the machine refused to boot. And, you know, I did manage 17 million credits on GPUGrid before I gave it up. My GPU's are GTX 670's, air cooled. We tried sealed liquid coolers, but they repeatedly failed. Even if the GPU's did overheat, I would think that would have initiated a shutdown of the crunching before actual damage to the cards. I believe that is what happens when CPU's overheat, a machine will shut down prior to damage.
13) Message boards : Graphics cards (GPUs) : Shot through the heart by GPUGrid on ATI (Message 28123) Posted 22 Jan 2013 by Richard Mitnick Post: O.K., now I know the score on ATI. So, I could go the other way: I could run GPUGrid as the only GPU project on the current machine, and run the others, EINSTEIN, SETI, and add MILKY WAY, on a machine with ATI. But, there remains the question, part of which I posed above: is there any reason that GPUGrip would create difficulties on any machine with decent Nvidia cards when it is the lone GPU project? After all, before I finally quit the project, it amassed 17 million credits. As I said above, this machine was rebuilt three times suspecting other problems than problems caused by any one project. It only calmed down once GPUGrid was no longer running.
14) Message boards : Graphics cards (GPUs) : Shot through the heart by GPUGrid on ATI (Message 28109) Posted 22 Jan 2013 by Richard Mitnick Post: I was planning out a new computer, a Maingear F131, with the express purpose of crunching GPUgrid. I already have a machine, a Maingear Shift Super Stock with Nvidia GTX 670's. For whatever reason, GPUGrid did not do well on this machine. I had to detach from the project. This machine kept failing. It was totally rebuilt three times, and what finally seems to have settled things down has been the removal of GPUGrid. Why this was a problem I have no idea. GPUGrid was the impetus for this machine. The machine is currently doing GPU crunching on EINSTEIN and SETI so far with no difficulties. Maybe various GPU projects just do not play well together. So, I wanted to plan the new machine with ATI cards. Apparently, GPUGrid does not run on any ATI cards. Am I correct about that, and is there any hope for the future?

16) Message boards : News : CUDA upgrade for long queue (Message 27895) Posted 1 Jan 2013 by Richard Mitnick Post: The 301.42 driver (and higher) will be ok. Thanks. I am relieved. Playing around with Nvidia drivers is not my cup of tea.
17) Message boards : News : CUDA upgrade for long queue (Message 27889) Posted 31 Dec 2012 by Richard Mitnick Post: So, I am on CUDA 4.2.x; but driver 301.42. There was a new driver out, maybe 304.x or 306.x which we were advised to avoid. So, what would be the proper driver number now acceptible? Thanks.

20) Message boards : GPUGRID CAFE : Do screen savers constitute the computer being "in use"? (Message 27611) Posted 7 Dec 2012 by Richard Mitnick Post: I have a computer the sole task of which is to crunch especially GPUGrid and other GPU projects. My configuration is to not run GPU while the computer is "in use". Since BOINC is all this machine does, just looking at the task list gets really boring. Just for variety, I thought about running project screen savers. But, does this constitute the computer being "in use", would screen savers stop GPU tasks from running? Thanks.
