My 2 i5 rigs' CPU's make up around 20% of their total RAC alone without fuss so why not use them? Cheers. |

Quite strange thread. OP proposes to stop CPU crunching for SETI.... but use CPU for another BOINC projects. What about _their_ inefficiency and damage to environment then. if these argument so matter for OP ?? Maybe worth to consider, not now, but in timescale of 2-3 years to cut own left hand? Cause it operates less effectively than right one (left-handed peoples read this reverse) ... Pointless, just pointless. |

What about the people who DONT want to run other projects on their computers ? I don't and I aint going to be forced to coz seti abandons cpu use!! ??? You don't know me or how I feel all you know is I only run seti . The day some one tells me what I use my computers for is the day Ipswich hospital A&E dept get very busy . MY computers , MY electric bill and MY choice what I do with my machines . I aint being told by anyone let alone some tw#t that dont know me !! ( and the missing letters a "a" ) |

One thing which has not been mentioned so far is that the purpose of projects like SETI is to also use resources that would otherwise be "wasted". So, if SETI would abandon all CPU applications, all of our pretty multi-core machines would (mostly) idle for the entire day. I know that maintaining many different applications for different platforms requires a lot of work, but in the end you'll reach more people that are willing to contribute to a certain project. And that is what matters most. |

Quite strange thread. Agreed, especially if you consider original idea of Seti just to use idle cycles. On modern CPU`s you can still crunch on 2 - 3 cores while streaming video or playing games whilst GPU is busy. With each crime and every kindness we birth our future. |

MY computers , MY electric bill and MY choice what I do with my machines . I aint being told by anyone let alone some tw#t that dont know me !! ( and the missing letters a "a" ) it's a good thing that we keep it civilized here! & btw, your bad language & remarks speaks more about YOU than about me. keep up the good work! So you just got LoL from me... :D Agreed, especially if you consider original idea of Seti just to use idle cycles. of course you can...on most projects (unless BOINC is running in high(er) priority), you can play games, watch videos...I never shut down BOINC while streaming videos from my laptop... ;) though, for modern games you would have to pause the GPU computing...my example was this winter while playing Star Trek Online - in 30d finished to 50+star Admiral rank of 60! SETi@home is one of the RARE projects that got one of the BEST (if not the BEST) GPU apps...a day would come one day, when running CPUs would be OBSOLETE - if not even now! why? We haven't got 1TFLOP CPU yet...mostly you get something up to 250-500GFLOPs in overclocked Xeons... The Haswell and Broadwell cores could handle 32 single precision or 16 double precision floating point operations per cycle. The top-end Xeon D-1540, which has eight cores running at 2 GHz, will deliver 256 gigaflops of raw double precision number crunching power – and do so in a 45 watt thermal design point. link: http://www.theplatform.net/2015/03/09/intel-crafts-broadwell-xeon-d-for-hyperscale/ all the while you get intelHD 6000 graphic card which has about 600-800GFLOPs, which is comparable to nVidia 460 GTX...source: http://www.pcper.com/news/General-Tech/CES-2015-Intel-Launches-Broadwell-U-15W-and-28W so, YES we do need processors...but they are running obsolete...from day to day! ;) non-profit org.

Out of my 7 BOINC projects only 2 (Einstein and SETI) can use a GPU. Others use VirtualBox to run a single executable on Windows, Linux, and Mac OS. This, in my humble opinion, is the best way to go. Tullio |

klik funny you say you don't have to stop the GPU's from working when streaming mmmm Can you tell me then why i have to stop my GPU's GTX 650's , when i watch video's ? MM seems to jump or stutter , why well it depends on the format of the video . try to play a game like Call of Duty try all the core going on the cpu and Gpu's and download a torrent file . I've had mine crash and got the blue screen of death . I have to turn of at least 1 core on the cpu or suspend the GPU's depending on what i am doing or suspend seti The idea of Seti is to use your computers SPARE unused cycles . AKA It's why is was designed with a screen saver. Also many other project do use both CPU and GPU. Just wait till your friend ask's you "man what did you do to my system it's real slow and the video's are stuttering" , unless the person know what seti is and it's explained to them some of the problems that can happen when it's doing seti then you may get a person that ends up a bit peed off with you and ask's you to remove it. I hope you told him not to run the laptop 24/7 they are not design'd to run 24/7 running one of the most demanding programs there is to run on a computer . I hope you explained to him that it will need the dust bunny's removed approx every 6 months and how to do that and maybe not run it in summer as it may over heat ?????? |

well I don't...but usually I watch videos on 720p & compressed! works fine, no problems...can make video if you would like it? ;) why do u have problems? don't know...until I gave a look...but you're too far for a peek... I would ask someone or post a topic on a forum...to find a sollution, here: http://setiathome.berkeley.edu/forum_help_desk.php of course I had problems while playing Star Trek Online...so I just GPU snoozed BOINC, not snooze all... ;) your BSoD are now getting me to some questions: 1. your PSU is not strong enough & it will fry your MBO (maybe also something else) if you keep using it! see if your CAPs are bulged 2. you have a problem with other hardware, usual suspects: memory, HDD...check memory with MEMtest86...check you HDD with some data program! 3. you have problems with drivers for network card or sthg similar... Why I don't have problems with my computers? no BSoD...all of them are maintained & serviced by me...some of them were build by me! ;) Screen saver is YESTERDAY use...NOW those apps use (usually) small amount of memory, compared to what OS needs to run normaly...also now, BOINC used on GPU can't see any screen saver...the idea was evolved from being "screen saver that does some job" to "app that is a part of cloud computing grid"... ;) tested the youtube...works fine! also, when you use TThrottle program, than the BOINC throttle is regulated by the temp of the CPU/GPU core...so if you do video, TThrottle will get you down to 0-40% of GPU...if not, it will go to the top 100%! no hickups... laptop is run, when it's run...have no problems with that! only my computers run 24/7...but I'm un-ortodox in some areas... ;) TThrottle is put on 65C...so, no - it won't overheat...& I'll clean it for him every few months! ;) non-profit org.

klik did you even noticed when my join date for this project is ??? I think i know a bit about this project mate I built the system i have now and all the system i've had for the last 16 years .......... Did you even bother to look at my spec's for the computer mmmmmmm I also noticed you passed straight over some of the posters that have been around a lot longer that you have and are even part of the Lunatic's group that have written some of the code so maybe you should listen to those of us that have been part of this project for oh say 16 years |

well, I also joined in '99 or '00...but had my university email listed here! & forgot the password...but, as the cancer research came with UD.grid - gone there...my grandma died from cancer & wanted to help cure that disease! then switched to WCG in 2006. & continued to donateover 47y of CPU time in that grid... when GPU calculation came with the awailable GPU to me, I added SETi@home...been here 'cause SETi@home is most un-intrusive app for GPU computing! probably something is wrong...mine computers don't have BSoD while using utorrent (though I use it only on 2 computers)...& don't have problems with videos, though I run only 1 app on 1 GPU - that is my setup, 'cause I don't have so much power on GPUs...GPU is 90% stressed with 1 task! ;) I've sent you some ideas...use them or don't! ;) of course, you have my bowl... but also, you are here for 16y with all that CPU power got you to 6M points...I'm here again for a 1y & have 1M points...with ONLY 3 cards going! ;) non-profit org.

Cool it, guys. To each his own. Eric has often made a point of welcoming everybody to this project. Which means you can run a measly 15 year old 1Ghz AMD single core for some 20 hours a week and STILL hand every task in on time. Which gives the amazing RAC of 5. OR you can have a couple of monster machines and rack up an RAC of half a million. Or anything in between. Everybody is welcome for the resources he/she donates, big or small. Nobody is above any other. Anybody getting abusive about somebody else's choice of what resources to donate to the project will find that Cafe and Politics aren't the only places kept orderly by the mods. Discussion is welcome. Flaming isn't. Don't make me go looking for the hat. A person who won't read has no advantage over one who can't read. (Mark Twain) |

Well klik i have done other projects 2.2 mill on einstein an 13 mill on Bitcoin Utopia , 9,500 at the LHC and 9,500 on VLHC@home plus a few years on and off the project most of the 6.3 mill has been done in only the last 12 months aproxx 1 million in the first 15 years the rest aprox 5 mill in the last 12 months And as for the system giving me the Blue screen of death maybe it's because i run all 8 cores and do 3 units per GPU , nothing to do with BSoD or my PSU which is a 750 watt single 12 volt rail PSU that can give 740 watts on the 12 volt lines . Umm i think 16 gig of ram is plenty and it's water cooled i have a 20 meg naked DSL line and 4 1 terra byte drives . I have lost GPU's because of over heating a 9400 GT So i hope you have set your friends system up so it does not stutter and explained a few of the things that can happen when running seti . I also have a duo core lappy and a second machine which is a Quadd core but i am not running much on seti until i can get a better GPU the the GTX 220 just not worth the cost of extra power usage and it can only do 1 units on the GPU other wise they take to long to do 5 hrs which slows the RAC down to much better to do only 1 with that card |

Everybody chooses their own projects...I will not comment on other people choises, 'cause it's all about personal preferences...and we know all that in those we do disagree... ;) With this tool: http://www.extreme.outervision.com/PSUEngine it gives that you use 515W in peak power - without WATER PUMP...so add that up! ;) so I would on your place check the RAM...my one system has worked OK, but occcionally give me BSoD or "black screen" or stoped at some given time -> MEMtest86(+) gave me a clue, it was a RAM... :/ Sorry to hear that...did it go out in the 2y warranty? As I've mentioned - I did...when using the SETi@home on a laptop, I always use TThrottle (but you have to have a newer proc than P4)...on my laptops TThrottle is set to 80-85% of Tjunc proc temp...on other peoples laptops it's set on 65% of Tjunc proc temp -> to keep them cooler! It really works great...so my suggestion is to use that program with using 100% of BOINC time -> gives best results! ;) So what preferences do you run on your laptops? ;) non-profit org.

Everybody chooses their own projects...I will not comment on other people choises, 'cause it's all about personal preferences...and we know all that in those we do disagree... ;) I'm using two of my laptops at home for crunching. An old Pentium M. Which is overclocked from 1.5GHz to 2.4GHz & runs 100% 24/7. I have actually been trying to kill the things for the past 2 or 3 years, but it just keep going! Them my newer i3-390m I am currently only using the GPU. As I can run either run 4 threads on the CPU at 100% or I can use the GPU at 100%, but the cooling in it is not sufficient to run both at 100%.

Are you talking to me ? The water cooling is a Cooler Master Seidon 120v Plus , pump power consumption is 3.6 watt Fan is 4 watt so going by you figures that's 521 watt max so not even 80% the PSU is 80 plus bronze and only a few months old . There nothing wrong with the PSU mate i checked the 12 volt on the Easy tune and it only drops to 11.76 if there was a problem with it , it would have done what the other PSU i used did and drop to 11.36 and then stop . I know why it gives me the blue screen of death it's not the ram . It also does not do it often only when i am asking it to do to much at one time and i'm getting someone trying to hack me while downloading a torrent other wise it's fine . Can't remember if the 9400 GT lasted 12 months or what . I live in a very hot country and the house was closed up and that is when it over heated plus back then there was not good control of temps like there is now with that card . |

I have actually been trying to kill the things for the past 2 or 3 years, but it just keep going! you got me an idea going on 4 my fathers PentiumM laptop T41...btw, how did you change the multiplier? That is why you should use TThrottle! This way either CPU gets heat from GPU on laptop...or GPU gets it heat from CPU... running both CPU & GPU is to hot...but using the TThrottle you equalize the top temps...& it doesn't overheat! ;) but you also, have a faster data release with your GPU, than with your CPU...did you choose GPU crunching beacuase of that fact? Are you talking to me ? Than good...al long you know what is the problem! ;) I know how it is...during the summer in Croatia temps go up to 40C! Even few days ago was up to 30C... ;) This year I've prepared myself with the throttling of the laptops & clean computers this spring... non-profit org. Play4Life in Zagreb, Croatia, EU |

also, here is my example: in almost 9y of BOINC on WCG with CPUs (always more than 3) I've done ONLY 5.33M points... in just over a 1y of BOINC on SETI@home with 3GPUs 1.2M points... hmmm...those GPUs kick ass! future definately belongs to them... ;) non-profit org.

Just looked at your machines you have 2 GPU's that are decent the others , Quadro's not that fast and your Raidon mm looks a bit old Are you using the IGPU's ? You would Be better off buying a few morw GPU's like the 730 and put them in the Xenon than running 5 computers and save electricty .And get rid of the quadro on the I 5 and put a 700 series GPU or 2 My current machine has done 4,863,405 in nine months and up until the end of January it was only working with 1 GPU and only 50% of the cores going You don't need TThrottle Bionic can do the same thing in the pref and the Nvida cards can use there own programs and all you have to do is turn the GPU fan up but instead of running it at 85% just turn one core off and turn up the fan on the GPU you will get a much higher R.A.C and what ever cores you have running can run 100% of the time and so can GPU's |
