[request] java benchmark on ps3 linux?

[nickblame]

is there a dude that has linux installed on ps3 any distro with java? to try out this: Whetstone based Multicore CPU Benchmark via JNLP please? just out of curiosity ... if it is running...

^^ That was the output of the jar. Guess it didn't work ....

if you care enough to help debbuging, I could try to send you a modified version to pass this error (other errors might show up though)

oh and did it get the available cores correctly?? linux sees ps3 as dualcore? (if yes then I guess it is not worth it)

If you send it, I will use it for debugging. Idk why the ps3 only sees dual cores because during the install phase, I selected all 7 cores but it didn't acknowledge them.

hit it again bro it should get past that Number Format Exception

The PS3 has a single multithreaded core giving you two cores, the other "7 cores" are SPU's which are not counted as processor cores and cannot be used by Java or Linux unless applications are coded for it. Linux will only report the two cores since it doesn't know what to do with the SPU's.


Unfortunately, Java programs cannot use the SPU's because there are no libraries for it. You'll have to try with C/C++. Google for guides on how to program for PS3 OtherOS.

Also, my advice is not to use Java to code for the PS3 since Java uses a lot of memory and the PS3 lacks in it.

I'm not coding for the PS3, the benchmark is for JavaSE compatible devices. Since there's a way to run it in PS3 it would be interesting to see the results.
Though gah your right it won't be anywhere near the true cpu power of ps3. bummer.

Sorry for the late reply! Was away from my ps3. Ran the jar again and those errors from the first one was gone but it just said "Running...." for 15 minutes so I guess the script jammed somewhere....

not really. if it something was wrong you would have seen it pop up in the console. it will most probably need ages to complete as dual core and totaly unoptimized.. its ok forget it
