Hi

As Manta incorporates SSE optimisations I was wondering if there was any
advantages to using the Intel compiler when compiling on an SGI Prism, as it is
an itanium architecture.

I am aware that gcc also has SSE compiler option flags available for versions
4.0 and above but we are runnning gcc version 3.3.3 (SuSE Linux) on our Prism,
so perhaps an alternative would be to get this updated instead ?

We are thinking of doing both but would welcome your opinion on which you think
would be fastest and why.

Regards

Shree
