https://svn.boost.org/trac10/ticket/9208 <p> On big endian machines (i.e. LLNL's Sequoia) the boost MPI implementation is broken. When a class's version is written to a packed_oarchive, the value (an unsigned int, uint32) is written as a 1-byte integer. The process sort of works on little endian machines where the least significant byte is being copied. On a big endian machine, this 1st byte is always going to be zero. I have put together a patch that explicitly converts the uint32 to a uint8 to avoid this issue. Feedback is appreciated. </p> en-us /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/9208 Trac 1.4.3 Steve Nolen <drnuke@…> Mon, 07 Oct 2013 21:46:33 GMT https://svn.boost.org/trac10/ticket/9208 https://svn.boost.org/trac10/ticket/9208 <ul> <li><strong>attachment</strong> → <span class="trac-field-new">boostMPIpatch.diff</span> </li> </ul> Ticket Matthias Troyer Tue, 08 Oct 2013 19:05:05 GMT https://svn.boost.org/trac10/ticket/9208#comment:1 https://svn.boost.org/trac10/ticket/9208#comment:1 <ul> <li><strong>status</strong> <span class="trac-field-old">new</span> → <span class="trac-field-new">closed</span> </li> <li><strong>resolution</strong> → <span class="trac-field-new">fixed</span> </li> </ul> <p> (In <a class="changeset" href="https://svn.boost.org/trac10/changeset/86207" title="Fixed #9208">[86207]</a>) Fixed <a class="closed ticket" href="https://svn.boost.org/trac10/ticket/9208" title="#9208: Bugs: MPI failure on big endian machines (closed: fixed)">#9208</a> </p> Ticket anonymous Tue, 08 Oct 2013 19:05:40 GMT
