<div>Dear Wien2k community,<br>
<br>
</div>
I am using Wien2k in a SGI cluster with 32 nodes. My calculation is running in 4 nodes that have the same characteristics and only my job is running in these 4 nodes.<br>
</div>
I noticed that one of these 4 nodes is spending more than 20 times the time spent by the other 3 nodes in the run_lapw execution.<br>
</div>
Could someone imagine a reason for this ? Any advice ?<br>
</div>
All the best,<br>
</div>
Luis<br>
