What compiler/language combination is most efficient for π calculation?
Performance is measured is the number of seconds to compute 4m digits. Lower is better. All the source code used is available on the pi_css5 main page. All results are from a Compaq Evo N800W with 2.4GHZ Pentium 4m processor, and 1GB RAM.
Source for other languages is welcome, as are recommendations for other 'interesting' compilers/VMs.
