Hello All

I have been working with Ned Slider on optimized Seti clients for Linux x86.
Since I am a Mac user I would like to compile also some optimized clients for Mac (OsX and Linux).

Is there anybody that would like to work and test on this project?

I have been using the "Altiveced" clients from Team MacNN earlier, but they seem not to work with the newer boinc versions.

Your comments are welcome!

best regards
Chris

If you can compile a BOINC that runs in OS 10.2.8, I'd be happy to help you test the SETI client on my old iMac that's just sitting there doing nothing but running my network. It won't boot in OS 10.3.x from the CD, so I can't upgrade it, and I hate to just waste it's processing capability.

Hi Beadman

It is quite difficult for me to compile binaries for older systems.
Unlike other GCC compilers, the one shiped with OsX seems not to like the -static flag which would allow you to run the client even if your system is a bit different than the one it was compiled on...

What kind of hardware are you using? (Processor)

It's a tray-loading iMac G3. Here's the specs:
Darwin Kernal v6.8
OS X 10.2.8
333 MHz
Bus 67 MHz
L2 cache 512K
iMac v2.2
Boot ROM 3.0f2
256 MB RAM
6 GB HD, 1 GB free

Thanks,
beadman

Thanks Beadman for the detailed information...

However I do not have access to a system with this OS version.
And as I sad before I do not have the experience to crosscompile the clients for your platform...
I have access to 10.3.x and 10.4.x there I will start to do some compiles.

Maybe somebody else can help in this special case?

Yes, please. Optimized workers are a good thing!

There is a thread or two on the optimization options I used for the boinc client and the seti workers in this forum.

Javalizard also made altivec seti clients, and they seem to be working with the newer boinc clients.

Thanks mikkyo

This is exactly what I am looking for.
I do not have alot of experience with the GCC options for PPC and I could not find good resources with flag recommendations.

I will test Javalizards client and benchmark it to see how much it gains.

I currently have a client under test that is using Altiveced-FFTW libraries. The first benchmark shows a gain of 16% against the orginal client. I expect to get more out of it if we throw in all experience...

I will get back here once I have a client that needs a public test.

Thanks, anyway, Chris. I'd even be willing to try compiling my own, but I don't have the first clue as to how to go about it. If I had a detailed set of instructions for OS 10.3.x, perhaps I could follow those while trying to compile something for 10.2.x.

If anyone knows where I can find a set of detailed instructions, please let me know.

Thanks,
beadman

Morning beadman

Here is Ned's guide:
http://www.pperry.f2s.com/boinc-compile.htm
http://www.pperry.f2s.com/boinc-compile.htm

Written for Linux but works the same way on Mac.
Just install the developer tools, check on Apples site which is the correct one for 10.2.8...

Just tried to compile Boinc under "Tiger" with X-code 2, GCC4, well it did not went to well, did not compile. Stopped with alot of errors....


The compiles of the same source code under GCC3.3 works without problems...

It should build fine under gcc 4.0.

mikkyo what source version are you using with GCC4?
I would like to verify with the same version if it is a problem on my system...


I just upgraded yesterday from 10.3 and did immediately install X-code and tools.
The error messages I get complain about wrong definitions in system files, not in the boinc code.
Maybe something not correctly installed on my system?

Well I will try to figure it out....

Thanks for the info, Chris - although, it appears I may not need it after all. I finally figured out why I couldn't get my old iMac to boot off the 10.3.x CDROM - the CDROM drive is bad. I tried a photo CD in it tonight, and it would even recognize the photos. I've ordered a new CDROM drive and will hopefully be able to upgrade to 10.3 on the iMac.

Well thats good news, so you will have no problem finding a working client!
