this is interesting.
Could you make sure that you include BOINC 6.4.5 so to support GPU reasonable well?


Is BOINC 6.4.5 stable and usable in the broad now ? - As I have released the distribtution, I had the impresstion, that to much bugs where in 6.4.5 so I have released the older stable version, which worked really stable.

The users can easily upgrade the BOINC client, if they would use the newest version. The only steps they have to do is to stop the BOINC client "sudo /etc/init.d/boinc stop", uprade the BOINC client and start it again ("sudo /etc/init.d/boinc start").

Last week, I have released Dotsch/UX 1.0. - Dotsch/UX is a Linux distribution for BOINC which easily installs and boot from a USB stick, hard disk and from diskless clients and also has some interfaces to setup the diskless server and the clients automatically.

Some news from SETI@home :
Gaurav has build a Astropuse binary for the PS3 which make a good usage of the SPEs....

can i run seti and ps3grid at the same time
like ps3grid use the cell and seti use the baes proses

Yes. Krunching-Keith has tested it. Please look at his thread : http://www.ps3grid.net/PS3GRID/forum_thread.php?id=65

SETI and Yoyo has PS3 SPE applications. SIMAP and einstein PPE only applications.

Very interesting !
Btw. what happens, if a no SPE application would started ? - Would the SPEs been released from the previos SPE work ?

There is a fundamental difference between the Cell processor and a normal processor: The spes are not sharable nor are accounted in the boinc CPU time.

If you start a PPE+SPE program and then the PS3GRID application (also PPE+SPE), it would look that it is running but instead it is just polling to see when the 6 SPEs are free. When the first ends then PS3GRID app really starts the calculation, but it may be to late to get credits because the BOINC client saw the PPE at work and summed up CPU time.

This may be the cause of some very long run that you have experienced in the past.

Have you forwarded this problem to David Anderson ? - I think he would be very interested at the PS3 at BOINC and would help you to sort this out.

As a further note I saw ResielSieve has a PowerPC app, but I could not figure out how to manually download it and the references in the forum are outdated with non working links. I did not have time to fully pursue or ask anyone on the forum.

I think, it would be worth to put a posting at the forums...

I haven\'t checked many other projects.

There is a table with the different projects, there supported platforms and a lot of more things at the inoffical BOINC wiki :

I haven\'t seen anything on any other projects about anyone developing specific PS3 apps (PPC+SPE) except for the one on the Seti forum (outside of PS3GRID that is).

I seen a posting from Gaurav at the einstein@home forums, that he would port the einstein@home application for the PS3. - I think, that he would work one PPE+SPE version...
Also, I not knew any other projects which would support the PS3 or PPC/Power on Linux.
But, I am involed in a alpha project, eventualy I can port the application to PPC Linux. But I have the problem, that I have no PS3 and only access to PPC/Power Linux systems and that the PPE+SPE needs heavy source code changes, which is a lot of work...

It looks like the email notification is not enabled or did not work. I have subscribed to some threads and did not get any notification for new posts.
A enabled email notifcation function makes it easier to following the different threads.
