Filippo, This is not strange. Most of the programs you have only use one core. Only a few will use more than one. Some games can do it, some photoshop filters... The Mathematica kernel also runs in one core. However, as of 7, Mathematica has parallelism built-in. This is not an automatic process though, and many programs and algorithms are not suited for parallelization. For an overview of parallelization functions, see guide/ParallelComputing or http://wolfram.com/products/mathematica/newin7/content/BuiltInParallelCompu= ting/ Cheers -- Sjoerd On Apr 6, 11:01 am, Filippo Miatto <mia... at gmail.com> wrote: > Dear all, > During a long computation I opened the taskmanager in windows and I > realized that Mathematica (7) uses only one out of 4 cores on my > machine. > Do you know why this is happening?
