Now that everone is supposed to use version 4.02, I guess many people want to use optimized clients. If you still use 4.00 you'll get invalid results and others who use 4.02 will also suffer from the old clients.

I've made an optimized windows 4.02 client osecw(optimized seti enhanced client for windows) with sse for now (compiled with Intel C++ compiler with fftw), but I'm not sure how faster it is than the official one. In my experience with the public seti@home, it will boost 10-20% at least. The official one is also sse enabled and linked with fftw. The advantage of osecw over the official one is this one is efficiently vectorized (sse is used to do multiple calculations at once) and IPO (interprocedural optimization) which will move or include several procedures inline or arrange so the app will work efficiently, so it must be faster than the official client, but graphics is disabled. And it isn't fully tested.

So use at your own risk. I will make sse2 version and Linux versions also soon. Anyone want non-sse version? It may take a bit time to build.

The link is osecw-402-sse.zip

app_info.xml and the client is included in this zip file.

Happy crunching!!

Since this isn't fully tested, if you have any problems please post here. But be aware, in this beta site, even the official client can get invalid results...:( We need a special attention.

PS: I also like beta testing :)

Even using the new Boinc version can get you invalid results...

One result by Rom Walton (using 4.70). ;)

yeah, you shouldn't expect too much for optimized clients. but core client is another story.

okay, this sse version is a bit faster.

osecw-402-sse-r2.zip

This is an sse version. I will make sse2 version tomorrow.

But warming. 4.02 sometimes takes much more time then 4.00, and that it's now standard. Don't blame 4.02, because it investigate WUs much more in many aspects. It may take more than 10 hours.

Thanks yet again, Tetsuji! I look forward to being able to run an SSE2 optimized version of 4.02 for my Pentium M. I'll be grateful for any optimization to offset the crunch time added from the enhanced analysis for Gaussians and Pulses. (It's great to see the extra science being done, but I got spoiled with your earlier applications completeing WU's so quickly!)

I compiled two versions of optimized clients...

osecw-402-sse-r2.zip for sse enabled processors (P3, AthlonXP, etc.)

osecw-402-sse2-r2.zip for sse2 enabled processors (P4, Pentium M, Athlon64, etc.)

osecw-402-mmx-r2.zip for no-sse processors (P2, Athlon, etc.)

But sorry, fftw cannot be built w/o sse, so the last one doesn't use fftw...

Happy crunching!!

three versions of optimized clients... ;) though the last one won't be so fast....but must be faster than the one compiled with normal VC++ w/o fftw.

Linux version will follow today or tomorrow.

it will be almost the same as sse2 ;) If you want, just a moment please.....I'll build one. For the time being, please use sse2 version.

Runs around 4600 seconds on my machine. :) (about 2 minutes slower than your previous 4.11 based on 4.00)

I've been thinking of building fftw w/o sse on Windows, and succeeded, but I'm not sure it's faster than the original dft.

Anyway, I made a new mmx version with fftw, so if anyone would like to try, please try this one and use favorite one. This is for P2 or non-sse processor users.

When I try this and rev 2, the older one looks a bit faster, but I tested only a little bit and may be wrong.

I saw on the front page they released a new 4.04 client. Will we need a new 4.04 optimized or just continue using the 4.02 optimized?

4.04's source is the same as the optimized 4.02's.
