<p class="MsoNormal">Dear all,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am trying out using MCPL files as input into simulations right now:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">COMPONENT sourceMCPL = MCPL_input( filename="/data/source.mcpl" )<o:p></o:p></p>
<p class="MsoNormal"> AT (0, 0, 0) RELATIVE Origin<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">When I run the simulation using simply “mcrun mcpltester.instr”, it takes about half an hour (the MCPL file in question is 24GB).
<o:p></o:p></p>
<p class="MsoNormal">However, when I try to use mpi (“mcrun -c --mpi=10 mcpltester.instr”), it takes something closer to 50 minutes. The problem seems to get worse (predicted run time for mpi=64: ~17 hours).<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Is there a way around it? Some special way of compiling perhaps?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thank you very much!<o:p></o:p></p>
