<br><div class="gmail_quote"><br><br>Hi,<br>I read the following in Paolo's announcement of version 4.1<br><br>
* mixed openMP-MPI parallelization: both CP and PWscf have been<br>
demonstrated to run on 65536 processors<br>
<br>1) How should one compile and run? I could not find it on the manual. <br><br>2) Could someone, please, suggest a strategy to mix OpenMP and MPI efficiently? How many OpenMP threads per node, how many MPI processes per node? Just not to begin experimenting from the ground. For a test case, I have a cluster infiniband-connected, where each node have two Quadcore Xeons, i.e., 8 cores per node.<br>
