Hi MPICH2 people,<div><br></div><div>May I know what does these error log mean? These error log occurr at the end of my main function, just before the last statement "return 0". By the way, I am sure the example program cpi.exe works fine on my small cluster.</div>

You may use valgrind to help you detect the error. <br><br>--From a stander-by :)<br><br><br><div class="gmail_quote">2011/1/1 Xiao Li <span dir="ltr"><<a href="mailto:shinelee.thewise@gmail.com" target="_blank">shinelee.thewise@gmail.com</a>></span><br>
