Building a production mpich


Up: Configuring  mpich Next: What if there is no Fortran compiler? Previous: Configuring  mpich

By default, configure sets up mpich to be compiled without optimization and with additional code to help in identifying problems and behaviour of the mpich implementation. Once mpich passes the tests (see Section Thorough Testing ), you may wish to rebuild mpich without the debugging code. This will produce significantly smaller libraries and slightly faster code. To do this, add the options 

-opt=-O -nodevdebug
to the configure line, and re-run make. You may also include multiple optimization options by inclosing them in quotes: 
-opt="-O -qarch=pwr2"
