Posted 13 Jan 2014 by Enric Surroca Post: frying a perfectly good CPU just because you can afford to when you could preserve it and give the machine to a poor kid whose parents can't afford the best is irresponsible, IMHO+1 At first I used stock fan and heatsink; but lately I bought a 120mm fan with big heatsink. I did this for I have my 2 Pc's on 24h/265 days a year (or so I try). I think investing on a big heatsink with a 120mm fan is a good investment; mainly because it can be relatively cheap. Recently the fan of my little GTX550Ti died; I bought a big GPU fan; too big in my opinion but that's what they had and I need it fast... so I had to buy it. From then till now I really see a difference in the processing speed (not of hours but quite perceptible). c u all |

Posted 1 Jan 2014 by Enric Surroca Post: @ Jan Vaclavik: you got the point. That's exactly what I meant. For a while I'll use both CPU and GPU (my little GTX550Ti). Obviously I'm hooked quite a bit to this project. Though there're others alsovery good. Still waiting to see the score of a 24k seconds GPU wu. Will have to be patinent. C U all |

Posted 31 Dec 2013 by Enric Surroca Post: Hi all. My specs: Q9505 // Nvidia GTX550Ti 1024Mb // 4Gb RAM. Most wu's take aprox. 12k seconds and give 480 points; got 1 wu of 24k seconds, still waiting to see the score. @Dagorath: I also agree; equal wu --> equal score. The thing is IMHP: In A@H GPU takes too much time to complete a wu; nearly the same as a CPU. I've worked for other projects; the difference in time is really important (i.e. Primegrid and Einstein) in CPUvsGPU. This leads to get more points for using the GPU; not for the wu itself but for the fact that with GPU You can go really faster so You can finsih more wu's in the same time. So, admitting that a GPU uses more power than a CPU, that it takes same time to process, and it gives the same score... what's the point of using GPU? (and I'll use GPU for sure) Freeing the CPU to be used in other projects? Only ask what other people may think; not me. I'll work both with CPU and GPU here, but others may think it a lose of time and energy. C u all |

Posted 12 Nov 2013 by Enric Surroca Post: Hi Assimilator1. Will checkout those links latter anyway :), btw you could of made them clickable :P (you still can, edit your post ;)). I'd like to do it. Sometimes they are clickable; and sometimes they're not. It's the magic of informatics. I don't know how to do it... Teachings? |

Posted 4 Nov 2013 by Enric Surroca Post: Hi all, I've been following this thread for a while. About what Dagorath says of mineral oil cooling here are some useful links: http://www.youtube.com/watch?v=t8shVDvMdo4 http://www.youtube.com/watch?v=FI9_2aczkOE http://www.youtube.com/watch?v=XGcW7Ii_BKo Other, more radical, ways of cooling can be these: http://www.youtube.com/watch?v=7zafznPlXbQ Hopefully some smiles may have been made. See you all |

Posted 16 Jul 2013 by Enric Surroca Post: Hi all, I've read a new this morning which may change Dagorath's view of SETI personnel. Here the link: http://www.nasa.gov/content/nasa-hubble-finds-new-neptune-moon/#.UeUNd9L0FxI Looks like someone in SETI has found something though not an alien... perhaps they have found the house of a primitive allien who doesn't know how to vibrate hydrogen... who knows. Dagorath... retractation on your opinion on SETI? @Dagorath: you said you lost conrtol of your bike. That's what you think. An allien, friend of someone inside SETI shot you an invisible beam of force for restlessly attacking the SETI project. Beware man, you cannot hide from them. About your problem of the hand... hmmmmm... really a big problem. You can always try the tactic shown in the movie american pie... |

Posted 29 Apr 2013 by Enric Surroca Post: cykodennis: yes, quite curious. Besides there're many other threads on the subject. Just look for them. We need Dagorath to tell his opinion on the matter. Maybe he is retired and having a peaceful life watching flowers grow in beauiful prairies... As it seem, Dagorath's hell is no longer available. Must admit I miss his commentaries |

Posted 18 Mar 2013 by Enric Surroca Post: Hi all, long time since my last post. Just wanted to tell all of You that the 4th BOINC pentathlon will take place from 05-18 Mai this year. Here's the link http://www.seti-germany.de/boinc_pentathlon/22_en_Welcome.html Asteroids is one of the projects that can be chosen by teams. Hope this project gets the most votes and so it's chosen to be crunched. My team will participate and we, also, invite any team to participate. See You all around here and hope to see You, too, in the 4th BOINC Pentathlon. |

Posted 18 Feb 2013 by Enric Surroca Post: You're right cykodennis. How many meteorites have fallen in the last 30 years with damages afterwards? IIRC, one of the last meteorites provoking a death felt in Arabia Saudi killing a dog. A global tracking system may be worth hundreds or thousands of milions each decade. Compared to this, what are a few broken windows in the middle of Siberia?. fortunately that meteorite was small; if it had had the size of the 2012DA14... there'd be some more than a few broken windows for sure... |

Posted 18 Feb 2013 by Enric Surroca Post: Ups, I forgot. Primegrid also allows ATI GPU's though this project is optimized for Nvidia GPU's. Don't know if your HD4250 will be of use in primegrid |

Posted 18 Feb 2013 by Enric Surroca Post: @Jan Vaclavik and Dagorath:it seems you both don't understand why people crunch only in SETI 24/7/365. Maybe this will answer this question. There's plenty of people stubborn to the bone; there's people whose fidelity is out of question. Join both, fidelity-stubborness and You have it. As I said I began with SETI, but soon discovered the rest of projects. Some are interesting and others, well... I don't even know/understand what they do (e.g.: DistrRTgen) but they also had their share of my little computing power. Only recently I started again with SETI with the goal of getting to 500k points (silly I know; vanitas vanitatis). Switching to the discussion of, is SETI's search method good or bad, let me ask all of You a question. All of us know hydrogen seems to be the most common element in the known (baryonic) universe; there are still many things unknown to us (specially me) meaning that perhaps still have to discover unkonwn natural processes/objects/stars/pulsars or whatever. The use of the vibration of the most common element may be seen by someone as aliens, though it can be the result of an unkown process we still have to discover (i.e.: what happened at the beginning with pulsars, the first of them named LGM). Wouldn't it be better to search for more rare elements? I have in mind elements as plutonium, uranium or the kind; elements not easily found in nature and that in most cases their existence in enough quantities together requires the existence of advanced technology. If I'm right, there are satellites (military) which search for possible nuclear explosions out in space (IIRC the serendipity which lead to discover the GRB's). Can a nuclear explosion be detected in long distances? Any way to make plutonium/uranium or so atoms vibrate the way of the hydrogen atoms? I think that would really tell us we've found intelligent ET's (if they don't kill themselves). I'm asking for I don't know if that's similar to the said vibration of hydrogen (the only vibration I know of recently is that of the mobile phones). @ Dagorath: you talk about wars against small and poor countries... like Iraq. That war was prepared for some oil companies who ruled that puppet (hmmm, named... Bush?) in orther to get Iraq's oil cheaper; the problem is that in the USA, it seems, there're still a few people who think their president owns the TRUTH (if he says so, so we do). USA is still a very young nation, still haven't learned that politicians lie and only care for their interests. They're mesmerized with their flag, listening their hymn hand over heart with a tear in their eyes and with the expression "the president of the United States of America" (hearing this everyday may make them feel safe). Obviously they're just a few but it seems they still have power. But don't be sad, wars have always been economical matters, beginning with the famous war on Troya, nothing else than the Greeks of the time against those who ruled the commerce with the pontus euxinus (add some gods, two cups of heroes, 2cc of love, 25 litres of death, and You have the Illiad). One day we'll forget about this, or simply die due to this. Who knows... |

Posted 17 Feb 2013 by Enric Surroca Post: Hi all. 1st: I spoke of a book I read. Found it: "Alone in the Universe: Why Our Planet Is Unique" by John Gribbin. Just in case someone may be interested in reading it. It's somewhat sad (for a lover of science fiction as me), for everything this man says leads to think there's nearly no chance to find intelligent life out there 2nd: Siran, I've my doubts Dagorath can ever be said to be a priest... perhaps with his alien friends (with whom he visited Cheliabinsk last day...). By the way, You treat him as a women, but IIRC, he once said he had bet something with his wife. Obviously it doesn't matter what he/she is, as long as he keeps as he/she is. 3rd. @ Dagorath. First question should be: are we (mankind) interested in finding evidences of intelligence out there? a) making mistakes is not proper nor beneficial for mankind. It's simply the way we're made (unfortunately). But fortunately we learn of them. What I meant to say was that SETI's been working for quite long. If what You say is correct, and their search method is not correct well, we've been for years being silly. So, we've learned from the mistake, so it's time to change the point of view and look for another search method. b)about probes. Here I agree with BilBg, probes may not yet be the answer to the problem. To begin with they're very expensive, prone to problems both in launch and in later operation. Taking them to the edge of the Solar System may take decades (i.e. voyager I & II). IIUC You didn't suggested sending probes to near stars, just outside the solar system to "listen" for others. That would pose another problem, keeping in touch with the probe; any order would've to be anticipated for long times for the orders to reach the probe (may be possible though...) IMHO, by now the better way to search for ET's is the passive way. With big antennas/radio telescopes/telescopes/freaks with telescopes, whatever; not going for them with probes. Where to put the devices? Moon, middle of the space, near Saturn or in the parking lot that's nothing I can say for lack of knowledge. c) poor Kozma Prutkov. I agree with Dagorath. This sentence may sound beautiful; may cheer up sad people but it's more sound-beautiful than real. The example given is very eloquent. d) about the hydrogen assumption. IIRC of my studies, whatever the senses other species may have, hydrogen will behave exactly for them as for us. You only need the correct instruments to detect the caracteristics. Another thing is if aliens may, or not, pay atention to hydrogen. I supose SETI uses the hydrogen for it's the most commont element in space and so easy to obtain. e) "Emitted by every star in our version of reality not necessarily in theirs." Are You thinking of a non-baryonic mater civilization? In this case, AFAIK, we'll have big troubles contacting them. Or perhaps thinking on parallel universes? In this case, I think it'll be impossible to contact them. f) ET's attitude: I think it was Paulli (not sure) who once asked: "If they're not here, where are they?". There may be ET's but: 1) they may not be technologicaly advanced like us 150 years ago; 2)may have technology enough, but happy simply watching their own belly button and finding it very beautiful; 3) with technology and ravenous to find someone out there (us in this case) whatever for (eating/mating/sharing with/talking to us). As Dagorath's says it's obvious we can only count with ourselves (unfortunately when ruled by people like nowadays politicians) g) "It is stupid to assume they are social. Maybe they are smarter than us and unlike us realize they ought not to go advertising their presence until they have the technology to defend themselves against creatures that hear the advertisement and come looking for food." Afraid of what ET wants to do us with his red finger, Dagorath? Don't worry we can always send a diplomatic like Bush and they will run away and never come back (http://www.youtube.com/watch?v=tlcE3HVRlRs). Unless they have the skill to make wormholes we won't see them in a time; and if they have the skill and want to eat us, we better have a pepper bath to be tasty. h) Final question Dagorath: assuming You also want to know (not contacting/talking/partying new year's eve)if there's life out there, using a passive way as SETI what would You suggest to look for? Hope to hear from all You soon. |

Posted 16 Feb 2013 by Enric Surroca Post: Hi everyone. I open this thread to accomodate a question by Jan Vaclavik. Can't tell You wich projects can use the GPU You say (HD4250). What I can tell You is that with ATI GPU, projects require a double precision GPU. In this link You'll find out which of the ATI's GPU have double precision http://en.wikipedia.org/wiki/Comparison_of_ATI_graphics_processing_units AFAIK, the projects best suited for ATI GPU are: Milkyway, Moo!wraper, Collatz and recently Poem (but with specific requirements and it's not, for me at least, easy to know how to do it). |

Posted 15 Feb 2013 by Enric Surroca Post: Hi Dagorath. Very good the comparation of probabilities (the lump and the pig, :) ). As You may know the way I choose is my bussiness alone. I respect Your opinion and must agree that you, for sure, are more right than me (never forget I'm an absolute noob in these fields; didn't know, nor understand, what you said about the vibrations of hydrogen; last time I studied chemistry&physics was nearly 20 years ago). A few months ago I read a book which was about extraterrestrial life and intelligence. The final line, acording to the author (an astrophisic, astronomer, don't remember exactly though if interested I can search) was that life outside Earth did exist; intelligent life besides that found on Earth? he concluded it was really difficult to find any. So, are we a weird natural experiment? A joke of nature? Perhaps. Obviously SETI is looking (perhaps in the wrong way as You say) for the existence of old signals from others out there. What I meant was that even though the chances are extremely low (or non-existent) we should (not MUST, ok) give it a try. Lest not be said we never tried. IIUC, You think SETI is a waste of time and useless (correct me if I'm wrong). Well, it would not be the first thing mankind has done which was, a priori, useless. But never forget one thing: how many discoveries have been made when looking for other things (or even not knowing they were looking for something)? Pulsars, radiation, peniciline, and so on if I'm not wrong... Perhaps one day SETI will proof to be useful for something (even if it's only to show how silly we've been to search in that way). On the other hand watch SETI as a very big useful tool. How many of nowadays crunchers started because of SETI (even the movie "Contact")? Most people start there in the DC world and then switch to other projects. So in most cases it's been thanks to SETI that projects like this get so many crunchers. I'm one of this: I started with SETI and soon learned there's a world outside SETI on the DC (my stats on the DC show it clearly); and at the end I found this community. Surely You won't agree with me, but we always can do the kabuki dance as You said before lol lol. Hope to hear from You all soon, as I really enjoy this forum. |
