Go in my machine is much BETTER than results in shootout.alioth.debian.org

[Dorival Pedroso]

Hi,

I've ran the n-body benchmark code in my machine (Debian Linux 3.2.0-2-amd64 #1 SMP x86_64 GNU/Linux -- Intel Xeon X5482 3.20GHz) using the latest Go tree (hg pul/hg up @ the time of this message) and got some really good results (see below)!

I'm sure my Gfortran compilation is wrong since Go is almost twice as faster than the Fortran code... Also, the C++ and C codes are faster than the ADA one (opposite to what is shown in shootout.alioth.debian.org).

Does anyone have further experience on this? (for convenience, I'm attaching some files from shootout.alioth.debian.org alongside my Makefile)

Cheers.

by the way, here you are the run.bash file
