According to this bit of Wolfram news from July 12, 2005 at
http://www.wolfram.com/news/mathematica52.html:

Mathematica 5.2 also supports automatically threaded numerical linear
algebra on all mainstream platforms, enabling linear algebra
operations to automatically run in parallel on all available processor
cores whether multiple or multicore CPUs. Mainstream multicore-based
systems are now available and are expected to be ubiquitous by early
next year, including in notebooks and entry-level systems.
