Post: I recently upgraded to the RX 480 and am wondering what I change to set the GPU to two concurrent tasks? I was looking around in app_info.xml, and i'm not sure exactly where. I am running the Lunatics 0.44 AVX and ATI5 clients. I have the CPU where I want it with eight simultaneous threads, but since the GPU seems to not be maximum, I want to up that to two tasks. |

Post: And the signal strength over time could simply be fringe reception which might just last that long at a really LOW signal strength. Define "Fixed Satellite" for me. Please use the ITU definition. |

Post: is lunatics working on a new enhanced client? A little is better than none, and all modern CPUs since Sandy Bridge have it. |

Post: is lunatics working on a new enhanced client? Will it take advantage of AVX2 in addition to AVX? In my own benchmarking, it can be up to a 90+% increase in speed. |

Post: Until not that long ago I was running a gtx460 with a 6 core amd phenom cpu. A few things to think about based on memory. First is, if you intend to do any AP tasks you will need to free up at least one cpu core, also don't expect to run more than one AP at a time. Another thing is make sure you kick the dust bunnies out very regularly as these cards don't like running hot for extended periods, and, to the same end, don't expect to overclock the GPU, as you say it is an old card and it will be showing signs of its age. So, it could be that I have it set up to do two when there isn't enough RAM for that? |

Post: I keep getting inconclusives on the Astropulse tasks with a GTX 460 that I have obtained (yeah, it's old, but we aren't rich) using the most recent Lunatics Cuda optimized V7 client. The regular multibeam SETI V7 tasks all validate without error. I don't want to get s*itlisted, so does anyone have any insight on the GTX 460? Current config is set to 0.5 (two simultaneous) on the GPU, and eight simultaneous on the CPU. i7-4790K @ 4.7 GHz (unconditionally stable), 32GB DDR3-2400, GA-Z97X-Gaming G1-WIFI-BK motherboard, H100i GTX cooling, PNY GTX460 @ 840 MHz GPU / 1900 MHz RAM (valid with everything I throw at it, except Lunatics Astropulse). |

Post: We agree on much. Speculating on what different levels of advanced civilizations might be capable of isn't a total waste of time, but this kind of mega-engineering explanation reminds me of Geraldo digging up Al Capone's "secret vault". Actually, it's a fun exercise, but we do need to use some common sense. I'd like to know more about them before we openly say "Hey there!".  "Wanna come over to my place for dinner? [Hmmm... Maybe with sautéed onions, and a bottle of their Chianti?]" |

Post: It would be interesting if it is a star on the verge of transition into a Red Giant. Firsthand observation of how a yellow star dies, well, at least the first stage of that death, long-term observation would be in order. |

Post: I believe it is stupid to believe that ET isn't out there, but if the theories surrounding this one prove true, Hawking is right, and we here on Earth should be VERY WARY of initiating contact with such a civilization, with such capabilities. Ask Stephen Hawking. He makes a bit of sense on the topic. I think this whole idea is rather absurd too, but let's entertain the scenarios of such a theorized civilization. Enough Dysonian technology to block out 80% of the light from a star? How much energy did that take? How much material did that take? Where did it come from? How was it refined? How many were involved in building it, and for how long? And lastly, WTF does any civilization need that much energy for? For energy, there are many other more practical means of obtaining it. It's estimated that using direct current Fusion techniques lacking any form of neutron activation, 100-150 tons of 3He can power the entire Earth for one year. That's about the size of or a little lighter than one single coal train. When options like that exist, Dyson looks like the idiot, as do those proposing rather absurdly sized "Dyson Swarms" of solar collectors, etc... But, entertaining the theory being laid out, such as in "The Atlantic", Let's entertain some other theories as well, as to if they have discovered other means of travel, and a way to keep from being turned into a plasma by collisions with junk, and can actually travel long distances. Word is that this system in question doesn't actually have any detected planets. If they can travel somewhere, build such shit, and somehow evade the normal problems such as the inverse of the square of the distance attenuating the collected energy to the point of being completely wasted effort.... Surveillance would be in order to determine the entire nature of such a civilization before initiating contact. Maybe all of the methed-out drunk crazy rednecks in Moose Turd Montana are right and they could be coming here to stick things up redneck butts, and choosing to carry on the genetic superiority of such intellectual giants as Nancy Leider by knocking such intellectually acute women up. No, I think people need to mellow out, and in many cases, take their Thorazine. What we have here is some kind of natural phenomena. It's just common sense. We are more likely to find some civilization at or near our level of technology than we are some absurd shit like has been proposed in this instance, and even then, before they discover what massive numbers of low power psk channels can do for them. Look at what Earth's evolving transition to digital modulation is doing to Earth's signal strength. Our signal strength is dropping rapidly. It could be that forms of RADAR will be more practical to search for, as those would be used pretty much in perpetuity by any civilization discovering it. It's hard to replace. Of course, maybe the crazies are right. Entertaining the present theory for instance, we probably won't have to worry, as the laws of physics state plainly that such collected energy would by useless to a different solar system, and the lack of planets would simply indicate that their crazies convinced their leaders to allow that energy to be transmitted to their planet... Ooops.. What planet? Maybe all of that energy vaporized their planet through a simple command and control loss of the collectors and power transmission....After all, such a system would have to have the most amazing impossibly high levels of fault tolerance. "WERNSTROM!!!!!" |

Post: I find the ET idea in this case to be highly unlikely, and that this will probably be able to be explained by natural occurrence. The problem NOW is that the kind of people (outside of the research community) that this idea has been seeded into the minds of are going to blow it all out of proportion, and weave this story into their mind-bogglingly vast and intricately interconnected web of conspiracy theories. This does make the dish time necessary, just to prove that it probably isn't ET. The hardcore ones won't even believe the followup unless it says it is actually ET now, and a natural explanation now actually reinforces their conspiracy theories saying that it is ET. I support dish time for this project even if all it does is say it's a natural phenomena, if only just to shut up the majority of the crazies (except the hardcore ones, for whom such will only reinforce their belief that it is ET). I believe it is stupid to believe that ET isn't out there, but if the theories surrounding this one prove true, Hawking is right, and we here on Earth should be VERY WARY of initiating contact with such a civilization, with such capabilities. I find the ET theory on KIC 8462852 highly unlikely out of basic practicality. Even if we could do such "Dyson Swarms" of solar energy collectors, nobody in their right mind would allow the collected energy to be beamed to the Earth. If you can't grasp why, there is an easy to understand explanation in Futurama S05E01 "Crimes of the Hot" starting at about the 09:15 time mark. We would be rather stupid to think that such an advanced civilization has no freaking common sense, and would actually allow such energy transmission. |

Post: well check your temperatures and cpu usage. those are nice indicators it is running my only complaint is that it could actually crunch harder. prime95 runs significantly hotter. oh, and the lack of the data view screensaver. |

Post: I'm completing and getting new work units, but my points seem to be stuck since yesterday. Okay, thanks. I posted this over there as well by your advice. Is this a case of just a whole new batch of data, and everyone is getting different work units now, and it's all-new? I should be up 10k +- 2k. |

Post: interestingly I have a smattering of VLARs now on the Mac Pro {allocated to CPUs}. I'm babying it, but Kudos to Urs/Raistmer for the radeon munching away, and the stock CPUs doing their thing. Have enabled 4 of the sixteen threads for now, just to see how hot it gets in here. So Far looks like very ugly computers with a half sucked lozenge look, do pretty good :D Looks like everything is running smooth again. I am noting ten astropulses in this batch (about 60 CPU hours or so), and possibly a larger than average number of VLAR too. it looks like the mix is changing to something a bit more diverse than it's been in recent months. |

Post: I hear a strange groaning sound from Berkeley - could it be the splitters spluttering into life? Let's hope so. I thought it got angry with me for FINALLY hitting two million total for BOINC SETI, and was just wanting to keep this particular machine from hitting one million (under 10k away). Is there an ETA on WUs? |
