Hi,

after some nights I finally succeeded in the compilation of gcc-4.2.

Hello, multicore computer!
1
generation time = 0.052937
number of threads in main: 1
calculating product in serial (using the ublas axpy):
Serial Product time: 1.43089
parallel product time: 1.38502

the parallel version is slightly faster than the serial one. Why it is
faster can only be answered by looking at the assembler output of both
versions.
