I have not tested the PG compiler yet,</div><div>but will soon.</div><div><br></div><div>My latest changes were general code cleanup - removing unused variables</div><div>and interface routines, adding a little error-checking, fixing typos</div><div>in comments, that sort of thing.</div><div><br></div><div>Not all of my test platforms have the necessary libraries for the</div><div>observation converters, so they are untested on all but the Intel</div><div>compilers on the NCAR mirage cluster.</div><div><br></div><div>I did discover that if you use the Intel 10+ or newer compilers in</div><div>a production environment (i.e. at some optimization greater than -O0)</div><div>you should remove the -fpe0 flag and use the -ftz flag instead.</div><div>The code !crashes! with -O2 -fpe0 (but not with -O0 -fpe0) and works</div><div>just fine with -O2 -ftz. The Intel docs indicate that -fpe0 is also</div><div>much more of a performance hit than -ftz (flush to zero). I made the</div><div>appropriate comments in the mkmf.template.intel* files.</div><div><br></div><div>Cheers -- Tim</div><br><div>
