Any work performed or produced as a result of use of the Materials cannot be performed or produced for the benefit of other parties for a fee, compensation or any other reimbursement or remuneration.

This could possibly impinge on seti/BOINC funding to UCB.

I don't see how, as long as the person using the compiler isn’t being paid to do so by UCB (or anyone else). But, as I’ve said before, IANAL.

I agree with Odysseus here.

I'm having trouble with CVS - I know someone posted how to get the enhanced CVS sources, the ones you get with the command from http://boinc.berkeley.edu/source_code.php are 4.xx. Can anyone paste the correct CVS checkout command again please? I'm too tired to wade through threads...

Regards,
Simon.

--edit
Never mind, found it by browsing the CVS web viewer.

cvs -d :pserver:anonymous:@alien.ssl.berkeley.edu:/home/cvs/cvsroot checkout -r setiathome_enhanced seti_boinc

- for anyone that's interested :o) That will grab the correct sources for you.

FYI:

CVS sources compiled without real problems for me on Windows.

Someone forgot to remove a file from the project - amd64AnalyzeFuncs.cpp. It doesn't exist on the CVS anymore, but it's in the project file still.
Remove it, builds fine.

I will be testing this with my flags and ICC/IPP vs. my 5.15 builds and see if anything changes.

Simon.

and times, nothink

but times are ...

have you Comparisons with the original Client

Greetings from Germany NRW
Ulli

As soon as I have results, I'll post them here :o)

Default 5.12 vs. Default 5.15 vs. Default 5.17

VS

Cruncher 5.12 My 5.15 My 5.17.

All on the same host, so the comparison should be halfway fair.

Simon.

Simon,

Are you using the "Express" (free) version of Visual C?

-- Ned

No, because I don't have a free 2003 version (and the 2005 express version croaks on some not-so-clean syntax somewhere, I forget).

Someone mentioned a free GUI-less 2003 version that's around - since the command-line options are in Visual Studio, I'm pretty sure that could be used to build.

For anyone interested in having Microsoft licenses available for personal use, you should really check out Microsoft certification...hint hint. Stop pirating, start getting free stuff from MS! Exams are much less expensive than licenses, but licenses are included when you take exams. Edumacate yourself ;o)

Simon.

I'll ask that any links to stable clients be posted in the New Optimised Apps Links --READ ONLY THREAD thread.

If they are test clients, please keep them here.

Ageless, that is exactly why I have not yet posted anything there.

I won't release things unless I'm sure about the license issues. Should I release anything, it will have been tested exhaustively on a number of different hosts beforehand.

I do want to make sure *everything* is as right as it could be before I take that step - can't speak for others trying their hand at optimizing.

Also, I have a couple of people as a test group. I won't risk a test build being less than perfect and getting distributed to lots of people, so I'm keeping it small for now.

Regards,
Simon.

probly wise move.. Can't wait to see all your efforts in action. My personal (and i'm sure from many others too) thanks for keeping to the struggle to build optimized apps and working so hard already.
Same goes to all others that have been doing their own work too. Its all much appreciated.

Yes it is by many of us, Very much appreciated! Excited also.:)

Thanks again :o)

Well, after spending a few hours trying to get the CVS 5.17 sources to compile, I'm giving up on them for now.

Instead, I'll schedule a nice test run while I sleep - default vs. Crunch3r vs. mine on Windows, same on Linux, all for SSE2.

Regards,
Simon.

Okay, here is the first round of test results. Bear in mind a test run takes me around 1-2 hours all in all (with collating results and rebooting twice).
The chirp_limit has been adjusted (to 1/2.5) so the units take comparatively less time, or one run would take 12-20 hours.

testWU-1 (AR: 0.60488405578199)

Windows 32-Bit

Default 5.15 with graphics
23m 33s (1411 seconds)

Crunch3r 5.12 SSE2
11m 30s (690 seconds) - 51.1% quicker

My 5.15 SSE2
11m 25s (685 seconds) - 51.5% quicker

Those 5 seconds difference are well within standard result variance, so I'd calll it a draw at this AR on Windows.

Linux 32-Bit

Default 5.12 (no X-Win installed, so no graphics? not sure)
19m 30s (1150 seconds)

Crunch3r 5.12 SSE2
14m 16s (856 seconds) - 25.57% quicker
My 5.15 SSE2
12m 49s (769 seconds) - 33.13% quicker

--------------------------------

Linux vs. Windows

Default client
Linux is 18.5% quicker.

Crunch3rs 5.12
Windows is 19.4% quicker.

My 5.15 builds
Windows is 12.2% quicker.

So to sum things up, Windows does seem quicker at this AR with optimized clients, but slower with the default (due to the graphics? probably).

Next unit I'll test has an AR of ~0.44, so scaling should be different there.

Regards,
Simon.

Those look like fantastic results. Nice :)

From what I have read about licensing issues, is not legal to distribuite any optimized app withouth the sources.
Here are some optimized apps, but no sources:

Simon, that is some very nice work there. Thanks for your efforts, and everyone else who is working on this as well!

baracutio has been notified that not offering source code for stuff you're distributing is against the GPL.

He used to offer Crunch3r's clients but took them down after being asked.

However, you're correct - that optimized BOINC app should also have a source package available to accompany it. It is not an optimized cruncher, though, but an optimized BOINC client.

Be aware that only made a difference when claimed credit depended on benchmarks. It doesn't anymore. So the real difference between using those and the default ones is zero.

Regards,
Simon.

For clarification purposes: The GPL does NOT require the source to be distributed with the executables. What it says is that the source must be made available if requested. This can be accomplished in many different ways and still be IAW the GPL. A text file with a link to the source can be included in the distribution or a simple statement telling people how to request it.

Thanks for the clarification Sarge!
