Interesting. I decided to play with this too (on a Lenovo notebook with two cores, running a 32-bit linux). If I choose to have Mathematica fire up another kernel "as needed", things run fine. However, if I ask it to start two kernels "on startup", the Benchmark runs for a long time (I haven't let it complete yet) and pegs both cores at around 100%. It also prints no output. Perhaps a bug? >> Could you elaborate a bit on this? I thought to make use of more >> than one core I needed to use commands like Parallelize. Are >> modifying the benchmarking code? > > No ...
