We do not have experience with this compiler, but PARI has been strongly optimised for GCC so unless intel compiler support the GCC extensions we use and Configure is tweaked to activate them for intel compiler, it is likely to be significantly slower. Specifically, the inline asm kernel rely on the "Extended Asm" and the "Statement Exprs" GNU C extensions. Of course, you are welcome to try and report the results! Cheers, Bill.
