How to get GCC on par with ICC?

[Paul Menzel]

Dear GCC folks,


Some scientists in our organization still want to use the Intel 
compiler, as they say, it produces faster code, which is then executed 
on clusters. Some resources on the Web [1][2] confirm this. (I am aware, 
that it’s heavily dependent on the actual program.)

My question is, is it realistic, that GCC could catch up and that the 
scientists will start to use it over Intel’s compiler? Or will Intel 
developers always have the lead, because they have secret documentation 
and direct contact with the processor designers?

If it is realistic, how can we get there? Would first the program be 
written, and then the compiler be optimized for that? Or are just more 
GCC developers needed?


Kind regards,

Paul
