What's going on here ? Something for free ?

[Crunch3r]

Howdy,

the thread title is kinda ironic.... while having a look at the "Users online" i can see a"dramatic"  increase of users online here. .

Seems as if something is free.

Well it is of course, however i'd like to encourage you all to sign up here and post some comments for ALL apps you've downloaded here. No matter what OS.

In the past i've noticed that most of the information we got back here regarding the apps, came only from the pre-release testers ( which i might add, did a great job !!!). However, a bit more response from those that download the apps and run them IS welcome.

Especially, now that we've added plattforms that haven't been (officially) supported before, like Windows on IA64 or Linux IA64/ALPHA or HPUX, SOLARIS etc.

It is in YOUR interest to sign up here and actively participate on further development of the optimized apps.
So take a minute, sign up here and leave us a note of your experience with optimized apps.

Thanks.

I did download the optimized apps for C2D/Windows, but I'm now trying to play with the source code myself in WinXP/CUDA.

I have tried to compile the standard nightly source in Visual Studio Express (I'm not entirely sure about the Intel compilers/files for Windows, and I plan to work on this for a lot longer than 30 days so the trial is useless to me), but that fails at setibioncdb.

Despite trying the guide by Urs on how to get the code to compile, I'm using code from a year after the guide was written and it seems to have changed.

I have downloaded the new apps, but it's too hot to run seti much - my CPU gets hotter than I'd like, and it makes the computer kick out too much heat.

Hi,
like i stated in that file, it was for last years seti@home beta version.
Now the devs at seti@home have made a new version, including many more changes to that old code and adding new codeparts. So, of course that file is now part of history.
Many of these adaptions to the VS8 compiler are now already in the code and therefore are obsolete. Other adaptions will have to be made to make it compile with VS8 again.
Maybe its time for a reworked guide based on the actual source code.
Until, take a look into the optimized sources thread by seti_britta. It includes many, many hints how to work things out.

These are the closest AR's I could find for comparison of Stock app and 2.4 on Pent M.

Thanks for the info. I assume your tests were run on Win XP ?

[WinyterKnight]

Correct assumption.
