Dual Core outlook

[malv]

Thank you Xavier.
Maybe this is too simplistic, but given two programs, one in Python the
other in Java or C#. Would this mean that running the latter on a dual
core processor would significantly increase execution speed, whereas
the Python program would be running in one processor only without any
speed up?

Is a Java program capable of this "out of the box" or does this require
specific additional code?
