Actually, I just looked at the CVS, and yeah, you'll need VS 7 (2003), because that's what the project file is for. You could maybe use a different IDE to compile it, but would have to recreate the project file and dependencies/libs/includes there. It'd be way easier to just load up that .proj file. I'll be trying that (have both VS 2k3 and Intel compiler here) in the near future. Donate to SETI@Home via PayPal! Optimized SETI@Home apps + Information |

Gecko That is one of the most intelligent this I have see posted! Crunch3r had paid for the software out of his pocket... and it was the latest.. including as he renewed the license for IPP... That was part of the delay for the optimized 5.12... It produced even tighter code... Opps water under the bridge... I would suggest that if it would/could somehow be donated to Eric, then some of the issues with Seti Enhanced might be solved... Pappa The license is $399. And one needs VC++2003 (not 2005, because Eric doesn't support it).quote] I have a Retail Box, MVS c++ 2003 STD Ed. w/ Std license (unused), VC++ Toolkit 2003 & Microsoft® Windows® Software Development Kit(R2) that I am willing to donate if it helps. For the IPP library, may I suggest that 5-6 of us could pull together and come up w/ $50-$75 each? I'm happy to go in $100.00 to start the collection. That would leave the remaining question of a beneficiary (who should at least not have to pay for the tools if they are willing to donate their labor for the benefit of the community). TMR & Hans, I don't suppose we could impose upon your kindness and expertise once again? How about after some heavy groveling w/ a hint of begging?[/quote] Please consider a Donation to the Seti Project. |

Gecko Before anyone spends money, the eval. compiler and IPP can be downloaded. To get "legal" we can then scrape together the bucks and buy something. At the same time, if Eric has any interest in doing this, he can get the Academic license ($100/compiler, $50/IPP) and as far as I can tell, there are no limits for distribution. |

If Eric is willing to do this, I'm sure we can cover his software expenses based on Academic. |

Jim R. wrote:Hi Ned, I'm not Ned, but I made the statement you refered to. I admit that you may be right about that license, however Office is not a compiler with which you can create other programs and sell them for a profit. Matter of fact, I have seen instances where the educational program is limited in some way, or it will post a comment into it's output that it is an educational copy. I'm not trying to throw any controversy into this. We've surely had enough of that lately! I was simply pointing out something that needed to be checked on thouroughly before someone paid the money for an educational copy then found out that it would not be legal to use. Here is another thought on this subject... Since UCB is an educational institute and SETI is a scientific project run by UCB, if Eric or one of the others actually working for UCB owned the license it may be legal for them to create and distribute apps since they are used for the project only. Maybe as suggested we could ask for donations to pay for it. (If my wife and I weren't both living off of one disabiltiy check I would surely donate!) As I said, I'm not trying to be controversial, just helpful. Jim Some people plan their life out and look back at the wealth they've had.

This is not strictly true. While a 5% gain in credits is nice with the soon to be beta version, in my experience the optimized 5.12 app gets over 25% speed improvement over the stock 5.1x apps, so more science is still getting done, and the quorum takes care of the 5% underclaim the optimized 5.12 client may making. I don't see where that makes crunch3r's client obsolete. XaaK |

This would depend on the number of people still using Crunch3r's app. I have already seen in Beta and in the Standard Seti using optimized apps, since the optimized app crunches faster, it has a better chance of being one of the first computers to report back. So if two computers happened to be running the same wu with optimized apps, they would have a greater chance to report back first and be the majority in the quorum. So here we would still have people complaining that they are getting less credit than they "deserve". However in this case they would be right! However crunching more wu's per time period would make up for at least part of it. Jim Some people plan their life out and look back at the wealth they've had.

However crunching more wu's per time period would make up for at least part of it. Well, it's a personal choice that they stand the chance to recieve lower credit/wu than the standard client. What people must realize is that any granting of credits has to be based on Berkeley's official clients, and not the optimized clients. We know Berkeley's clients will always be there, but as we have seen, not so with optimized clients. If you get more or less credit using an optimized client, that's your choice and it has to be looked at as temporary. However, if you do the math, 25% more wu in the same time period getting 5% less credit is still a significant net gain in credits/hr. XaaK |

However crunching more wu's per time period would make up for at least part of it. If those using Crunch3r's 5.12 app run it with a 5 day cache setting (or more) then they would nearly always be the last one to report their work and thus not affect the granted credit figure. Of course this would also make them be the "useless 4th result" as some would say but hey.....credit is credit! Boinc....Boinc....Boinc....Boinc.... |

Jim R. wrote:Hi Ned, Which is why I went to Intel's web site, and read what I could find on the subject. If you buy a copy using "student pricing" then there is a clause that says "non-commercial use only" which I think means you can't sell programs. The Academic price (for degree-granting institutions or professors at a degree-granting institution) does not have the "non-commercial use only" statement. |

Educational versions of software packages vary widely with respect to the restrictions on their licences as compared to the standard versions. In some cases they’re exactly the same as the standard versions, but don’t qualify for discounted upgrade pricing; in other cases the applications themselves are ‘light’ editions lacking certain features. |

There are three routes you can go to try an optimize an application. Recompile the application with a compiler that is tuned for your system. This is pretty much the least expensive in terms of time as you get a pretty good bump in performance but you give up compatibility. The processor will throw an error is it doesn't recognize a command it was sent. Make changes after compilation. This usually involves modifying the executable and rewriting the machine code by hand. Optimizers doing this can do things a compiler won't normally let you do. Technically they could detect the number of instruction pipelines and set things up in such a way that the processor could perform two mathematical operations at the same time. Or prefetch a specific block of memory they know is going to be needed within a few instructions so the CPU can set that up before it actually gets to the code that needs it. This is the most expensive solution, time wise, as it requires very specific knowledge about what the processor is capable of and how it works. Make changes to the source code. This option is less expensive, time wise, than changing after compilation but more expensive than just changing the compiler. Here you can run through perf monitoring tools to find out where most of the time is spent and look at the machine code generated. With this method a developer can change the source code around so that the compiler can make better choices about which instructions to use and when. This also generally works across compilers and processors. ----- Rom BOINC Development Team, U.C. Berkeley My Blog |

This might be due to what software/libraries you are using on your linux machine. If you use _autosetup to build the configure script on your Mac, you can probably copy the configure file over to your linux system. That may solve the problem. If you are using a prebuilt configure script, you might just try running _autosetup on you linux machine. Eric

I'm getting the exact same error message (g++ : no input files) under debian. (After running "./_autosetup", that is) Could you tell us what linux distribution you use to compile the seti app? Perhaps it would help if you posted a tarball of your complete seti folder, containing a working set of configuration files. (I don't know if this is possible, though...) Regards Hans |
