Firstly, the website lacks any kind of webmaster link with which to report problems. Subscribing to this list seems the only way. Bug reports - the link is to https://trac.mpich.org/mpich/newticket This appears to be dead - (not found in DNS). The same problem applies to all links under "release Information". Downloads. Page http://www.mpich.org/downloads/ The links http://www.mpich.org/downloads/tarballs/1.4.1p1/mpich2-1.4.1p1-win-ia32.msi http://www.mpich.org/downloads/tarballs/1.4.1p1/mpich2-1.4.1p1-win-x86-64.ms... do not work. I hope these can be fixed. Notice: This email and any attachments are confidential. If received in error please destroy and immediately notify us. Do not copy or disclose the contents.
