Greetings,

I *MAY* be getting a PS3 in the near future. If so I will be happy to run the tests.

Do you Good Search for Seti@Home? http://www.goodsearch.com/?charityid=888957
Or Good Shop? http://www.goodshop.com/?charityid=888957

Just wanted to say I have a PS3 testing the seti app, and it has just started to process WUs today. Shows 1st WU should be done in another 8.5 hours, 2nd WU estimated at a day and a half to finish.

link to my computers - http://setiathome.berkeley.edu//hosts_user.php?userid=179566

The PS3 is running Fedora 7 and shows 2 cpus being present but does not show any cell processors, so I am not sure if it is running your app at its fullest. Yellow Dog Linux did show 2 cpus plus 6 cells when I had it installed so not sure if the Fedora 7 kernel will make them available or not.

The best that can probably be done so far on SETI@home for PPC is to ensure that you are using a Cell based version of FFTW. You should also make sure that the Altivec code is active, since Cell has an Altivec unit.

As far I know, no translation of the SETI@home algorithms to Cell has been done.
If someone wants to undertake this, please do. Remember that if you distribute a SETI@home application binary, you need to make the source code available.

I must be doing something wrong. I already have BOINC installed and attached to PS3GRID. I decided to attach S@H to run when there wasn't work available for PS3GRID. I attached to S@H. Then quit BOINC, and downloaded this:

http://gravity.phy.umassd.edu/~gkhanna/sah-cell.tar.gz

I expanded the archive, and copied all three files into projects/setiathome.berkeley.edu, except for the BOINC client as I already have BOINC installed an running. The three files are app_info.xml, setiathome_2.3A_bin, and wisdom.sah.

When I restarted BOINC, I am getting from S@H "platform powerpc64-ps3-linux-gnu not found".

What am I doing wrong?

The three files are app_info.xml, setiathome_2.3A_bin, and wisdom.sah.
When I restarted BOINC, I am getting from S@H "platform powerpc64-ps3-linux-gnu not found".

Check app_info.xml again that all seti versions do indeed point to setiathome_2.3A_bin, and htat all have the correct ownership/permissions.

Thanks for the response! This is what is in the app_info.xml. Can I please get a little help on modifying it?

Well, you could try adding version 5.17 to it thus, but the problem is that it doesn't recognise the platform. Having a valid app_info.xml may address this.

The app_info.xml file must be located in the projects/setiathome.berkeley.edu directory together with the app and the wisdom.sah file.

oh, don't forget to do "chmod 775 setiathome_2.3A_bin", in case it was extracted as a regular file without the executable flag.

Thanks. I added the 5.17 section to app_info.xml. All the files have the correct permissions, and are in the correct folder.

However, I am still getting "platform powerpc64-ps3-linux-gnu not found".

How are others getting around this? Do I need to spoof some other platform somehow?

I just compiled the boinc source and then added the project directory contents to the working project directory. Without the SaH PS3 app it would report unknown and not do anything but add the computer to the project.

I did download all the rpms and the spe tar and installed it all first. I did not edit anything in the project files to get it running. I did edit one file to add vendor value of PS3 so it would show when you looked at the computer.

I am also using Fedora 7(moonshine) instead of YDL

After a reboot, the app_info.xml file magically started to work, and I was able to download a result. However, after about 5 seconds it failed. Here it is if anyone wants to look:

Now what?

So..... PS3GRID went down this weekend, and it sure would have been nice to have a S@H app working, so it didn't sit idle. Where do we go from here? I am willing to help debug anyway I can. Just let me know.

FWIW, I am running YDL, 5.0.1, fully updated. And BOINC 5.10.6, compiled by PS3GRID (link to it from their home page).

Dotsch wanted to see this. Perhaps it helps?
