Ciao tutti,<br><br>Pls does anyone know a simple way to fix this error which I got from running cp.x with 4 processors:<br>ERROR: 0032-117 User pack or receive buffer is too small (32) in MPI_Bcast, task 1<br>
ERROR: 0032-117 User pack or receive buffer is too small (16) in MPI_Bcast, task 2<br>
ERROR: 0032-117 User pack or receive buffer is too small (32) in MPI_Bcast, task 3<br>
<br>I googled and found:<br><a href="http://publib.boulder.ibm.com/infocenter/clresctr/vxrx/index.jsp?topic=%2Fcom.ibm.cluster.pe_linux43.messages.doc%2F0032-117.html">http://publib.boulder.ibm.com/infocenter/clresctr/vxrx/index.jsp?topic=%2Fcom.ibm.cluster.pe_linux43.messages.doc%2F0032-117.html</a><br>
which says:<br><span class="title">0032-117</span> Parallel Environment for Linux V4.3 Messages<br>

<div><p>User pack or receive buffer too small (<span class="synph"><span class="var">number</span></span>) in <span class="synph"><span class="var">string</span></span>, task <span class="synph"><span class="var">number</span></span></p>
<h4>Explanation</h4><div class="section"><p>The buffer specified for the operation was too small to hold the message.
In the PACK and UNPACK cases it is the space between current position and
buffer end which is too small.</p>
</div>
<h4>User response</h4><div class="section"><p>Increase the size of the buffer or reduce the size of the message. Error
Class: MPI_ERR_TRUNCATE <br></p><p>--------------------------------------------------------------------------------</p><p>I actually don't have a clue in which part of the program I should increase/decrease buffer/message size.</p>
Thanks for any help.<br><br>o.<br>
