Hi Franz

try:


Without SMP support
====================
./configure -prefix=/usr/local/mpich-1.2.1-pgi --with-device=ch_p4
--with-arch=LINUX -cc=gcc -cflags="-O2" -c++=g++ -c++flags="-O2" -fc=pgf77
-fflags="-tp p6 -O2" -f90=pgf90 -f90flags="-tp p6 -O2" 

With SMP support
================
./configure -prefix=/usr/local/mpich-1.2.1-SMP-pgi --with-device=ch_p4
--with-arch=LINUX -comm=shared -cc=gcc -cflags="-O2" -c++=g++
-c++flags="-O2" -fc=pgf77 -fflags="-tp p6 -O2" -f90=pgf90 
-f90flags="-tp p6 -O2" 

this works for us !!

Best
