Re: Comparison of Mathematica on Various Computers


Why look at compilers and libraries?  Note that the better performance
of AMD chips is consistent across different OS (Window, Linux,
Solaris).
Pressumably different compilers and libraries are being used.

We notice similar across the board superiority in testing  a suite of
applications to benchmark supercomputers, as noted in a previous post.

IMO the main reason is hardware: a better memory controller
integrated into the 64-bit chipset.  Mathematica tends to be memory
traffic intensive because of the list structures.  Our tests on 128-CPU

clusters were also memory traffic bound for a different reason:
each processor talks to each other through a VM system.
