Re: [CPMD-list] CPMD on PS3





Yirdaw,

we have  CPMD running on PS3 and QS20 blades - it is not officially 
supported because additional steps needs to be  finalized to get 
performance out of it -

major problem is that the spus works  at high performance in single 
precision and double is needed in most cases to have stable results - we 
are working on  iterative procedures
to get  double precision results from  single precision   iterations - 

This will not be supported yet in the next  upcoming release -  will let 
you know more soon and  will be interested to have people ready to test 
what we have - 


Alessandro

[CPMD-list] CPMD on PS3








Hello all,

Does anyone know if it is possible to compile and run CPMD on the new
playstation (PS3)?  If not, will it be possible to do so in the upcoming
versions of CPMD?

Thanks,

-Robel
