We do not generally maintain compilers, other than what comes with the OS. The current exception from this, is IntelĀ® Parallel Studio.

You can install additional compilers yourself or get help from your group.

However, you can find the compiler options used for the SPECint and SPECfp benchmarks here.

Also, the net is full information about compiler options. If you are using gcc you might find this link helpfull.
