I've successfully compiled and run PWscf on an Itanium2 machine using
the Intel compilers version 8.0 and the Intel MKL libraries version 7.0.
All examples seem to run correctly.
Which compiler are you using? Did you use the "configure" script for
configuration? Did it give any warnings? Could you post the "make.sys"
file used for compilation?
