<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;">Hello,<br><br>I have installed mpich2 on centos 5.4 x64 and everything seems to be working fine. My current GCC compilers are 4.1.2 and I would like to upgrade to 4.4 or 4.5. I would like to know whether I will need to recompile/reinstall mpich2 after upgrading the GCC compilers.<br><br>Thanks,<br><br>Raasik<br><br></td></tr></table><br>
