Sage is not using Multi Core CPU Resources!

[Saj]

Dear sir,

I am using sage-math in Xeon Workstation. Interestingly, its not using
all the CPU resources. one CPU is 100%. Rest of them are sitting idle.
My question is

- Is it possible to build sage with muti-Threading to support multi
cpu architecture.

Please help me out!

Thanks & Regards,
Saj

There are a very small number of specific commands that do use
multiple threads. E.g.,

sage: time k =bernoulli(100000, algorithm='bernmm')

It's possible to build the numerical linear algebra library (ATLAS) to
use multiple cores, but this is not supported in Sage at present,
except on OS X where it is done by default by OS X.

Otherwise, if you want to use the multicore/multiprocess power of your
"Xeon Workstation" to its maximum potential, you should run multiple
separate versions of Sage at the same time.

Hi,

will Grand Central on Mac OS X Snow Leopard make using
multiple cores/processors easier?
