Hello SETI@home community! Like you all know, you can let run opt. apps for to get double performance of your PC. So the science profit from it, because of faster calculation. I see a lot of 'wingmen' of my results which let run only stock apps. If I remember my first time as new member, over months I didn't let run opt. apps, because I didn't know that I could. Then.. I can't remember who or where - I got the hint. I guess random here over the forum. It wouldn't be better to announce on the first side of the SETI@home website, that there are opt. apps available? Of course, with hint because of all opportunities, difficulties and problems which can happen. What you think? |

do you mean advertising the 3rd party optimized apps on the home page of Seti? THats not likely to happen In a rich man's house there is no place to spit but his face. Diogenes Of Sinope |

I feel the stock apps are all you need. They are the work of the SETI@home scientists so it's with deep respect that I run their handiwork. Sutaru, why are you *always* in such a hurry? This is not a F1 race. Faster apps don't always equate to 'better for project'; in my neck of the woods, Haste Makes Waste. Too many crunchers have far too many VLAR CUDA 'error while computing' errors. Have to run re-scheduler, etc. Most don't run this so lots of wasted project time and bandwidth. Normal crunchers have to wait for super crunchers to dump their errors so they make it through the project a second time, etc. Other ways in life to have fun - not babysitting computers. :-) Remember the Tortoise and the Hare :-) |

Good insights for someone that joined the project 3 days ago...LOL...who were you before? Hi Robert, First time here. Friends are crunching S@H, Milkyway, Rosetta, etc. Decided to come on board; they have helped me getting started. I don't mind doing a few BOINC projects but I don't feel like babysitting the computer :-) Cheers, Giles |

We already have a link to Porting and optimizing SETI@home on the main page. However, this page isn't that good. The information about all the available apps you get first if you go from there to the Other sources of BOINC client software wiki page. And this page isn't that informative as it should be. This two pages should become just one, the list of websites where you can download applications should be under "Where to get executables" including the information, which of the apps can be categorized as optimized and which are just ports to other platforms. That way the list would be just one click away from the main page, which IMO shouldn't be changed, as that is what all "set and forget" users should use. |

Welcome Giles, One of the good things about the Opt-apps and the reschedular is that they either send back or move VLARs to the CPUs. A big part of the CUDA errors are caused by VLARs on CUDA capable GPUs running stock. As for the optimized apps, S@H stock apps have to be very generic which is why they are so slow. The Opt-apps are geared towards a specific set of instructions so that they use your machine's capabilities to the best advantage. With the use of the installer they are nearly foolproof to install. With the reschedular and a good cuda capable graphics card you can do at least three times more work and send the VLARs to your CPU where they run with no problem. I first started running Opt-apps because my machine was so slow the opt-apps gave me a fighting chance to get the work done without making my wingmen wait so long. The few problems were caused by my machine not the Apps I was running. The only "drawback" is that I have to watch these boards in case a new updated app is released. Even then it only takes a few moments to upgrade to the new app. PROUD MEMBER OF Team Starfire World BOINC |

Hmmm seems to me a lot of the code in the "Stock" Apps came from previous optimised apps...Oppps. Official Abuser of Boinc Buttons... And no good credit hound! |

No S***! And here I thought EK wrote most of the apps; what's next - Santa Claus is a myth? :-) |

Welcome to Seti
Actually Santa Claus is down in the Sourthen Hemisphere where it is warmer... EK is the basis of most of what is running. As there are some very talented people (users) that have been in Seti/Beta for both short and long times that have looked at the Stock code and found issues that were shared with Eric. The Net Result is what was shared back (fixes issues) gets incorporated into the Stock code (yes there are limits that the Stock Compilers handle or CPU specific that Seti does not do). Actually, the Administrators of Many projects that have used the input of talented "users" to make the Application (pick a project) work more effeciently. So it becomes the case of two heads are better than one. Boinc is about Solving Problems, and Users Helping Users. So while people want to tell you that running Stock code does not do as much work, it is true. No one should attempt to force you to do anything you do not want to do. People pick "Projects" according to their personal interests. That is how it should be. The only problem is that Boinc and Projects evolve. Keeping Users on the same page gets tougher. Volunteer Testers do a lot of work to insure the Stock Application works. Regards Please consider a Donation to the Seti Project. |

Thanks for your opinions. Giles, from where you took your knowledge about this project as new member? You are new, so we forgive.. BTW, welcome at SETI@home! The others explained it well.. maybe additional.. The SETI@home developers done very well stock applications. (SETI@home Enhanced / AstroPulse) Then there are members like you and me, which looked in their free time how to optimize the stock applications. Now we have this (small optimized) stock applications, I took an example of your PC.. [resultid=1442477133] v_vGetPowerSpectrumUnrolled 0.00008 0.00000 sse3_ChirpData_ak 0.00929 0.00000 v_vTranspose4np 0.00201 0.00000 AK SSE folding 0.00068 0.00000 AFAIK, this two AK entries are 'Alex Kan', one of the optimizer crew. The project can't send an application with (full) optimization to all PCs, because BOINC don't know which extensions the CPU have/can (MMX/SSE/SSE2/SSE3/SSSE3/SSE4.1). So the project send a stock (small optimized) application which can work equally on MMX and SSE4.1 CPUs. It's a pity that the BOINC client isn't smart enough to see which extensions the CPU have. The operation system see some, but max. is SSE3 AFAIK. So SSSE3 and SSE4.1 wouldn't be detected. If BOINC would have something like CPU-Z to detect the CPU extension, BOINC could DL the (full) optimized application automatically. I guess the project scientist would be happy if their science would be calculated so fast as possible. I would recommend that you take also the (full) optimized applications for your PC. Small look here in my -> <- (quick instruction). Your Core i5 750 @ 2.67GHz (OCed?) could maybe reach if 24/7 a RAC of ~ 3,500 (with full optimized application/s). If only with stock (small optimized) application/s the half.. ~ 1,750 RAC. So I think it's in the interest of the project to announce the possibility of optimized applications with more 'attention'. |

Salut! I am new to S@H here and have a question about the optimized applications. I have installed them using the instructions and everything appears to be running okay. BOINC is telling me that my WUs need 45 hours to finish but they are at 82% after only 1 1/2 hours with little time left to finish. Did I 'break' something because I'm sure it said 45 hours for the WU to finish? Thank you for any comments about this. |

Salut! That first time reported was just an estimate. It will gradually go down as Boinc gets to know your system better. |

Salut! Very nice. A new member and installed immediately the opt. apps! So this thread was helpful! Maybe it would be better to announce the opt. apps on the 1st side, also with attention? Niko, welcome at SETI@home! If you look to the Windows TaskManager (press [CTRL] + [ALT] + [DEL]) and you see names like AK_v8b_win_SSSE3x.exe you are fine. Also in the first messages of the BOINC Manager you should see something like found app_info.xml/using anonymous platform. |

Dear Sutaru, thank you for the welcome! I checked my BOINC log and the Task Manager and it is exactly as you said. I am using 3 cores of my CPU for S@H so I see AK_v8b_win_SSSE3x.exe 3X. I'm surprised that the S@H exe uses only 35MB. BTW, your RAC is crazy high - wow! Turbo Cruncher :-) |

Welcome to SETI@Home Giles. The project is a noble one that needs more people like you to join if we ever want to accomplish our goals. Do not forget to check out all the cool cups and T-shirts that they have for sale as well. Buying them supports the project.

I'm surprised that the S@H exe uses only 35MB. Why only 3 threads? You don't need to be afraid that you can't work like before at the PC if SETI@home is in the background. The CPU WUs of SETI@home have only the 'low' priority, so you can work like SETI@home wouldn't calculate. So you don't need to let idle one CPU-Core. Maybe in the future you are also infected with the SETI@home virus and you will extend your equipment.. I'm little bit surprised/shocked that I'm current the 29. of the world and 1. of Germany with my/this small equipment (RAC). [http://setiathome.berkeley.edu/top_users.php] |
