Given that the PS3 already runs Linux (see http://www.eurogamer.net/article.php?article_id=70611 for example), what chance of compiling the boinc & rosetta code for that platform? Why wait for Sony to offer? What am I missing, it seems such an obvious idea there must be some reason its not already been done? River~~ |

In very simple terms: the problem with the ps3 is that linux can only access one cpu, that runs at the speed of a slow pentium apparently. The speed of the ps3 lies in the combination of its 8 cores, to which linux doesn't have any access. So there seem to be 2 problems: a) Getting access to all cores b) write an application that works on parallel on all 8 cores. What can be done has been proven by folding@home, who increased their crunching power tremendously. Have a look at the other PS3 thread by Paydirt entitled: "PS3 preliminary crunching numbers". Given that the PS3 already runs Linux (see http://www.eurogamer.net/article.php?article_id=70611 for example), what chance of compiling the boinc & rosetta code for that platform? |

B-roy is correct, simply installing Linux on the PS3 and then running F@H or BOINC does not use the system well and performs at 1/10th or so of its power. |
