    <subfield code="a">&lt;p&gt;It was observed, that the RT-PICLS code ran by FWKT on the hypnos cluster was producing an unusual amount of system load, according to Ganglia metrics. Since this may point to an IO-problem in the code, this code was analyzed more closely.&lt;/p&gt;

&lt;p&gt;RT-PICLS was run with additionally provided input data on 64 CPU cores (AMD Opteron) in a single node of the hypnos cluster. Score-P 4.0 with IO-tracing support was used for profiling and tracing of the application. A developer version of Vampir 9.2 [3] enabled graphical analysis of the traces.&lt;/p&gt;

&lt;p&gt;Different file systems were evaluated for storing the output:&lt;/p&gt;

&lt;ul&gt;
	&lt;li&gt;&lt;strong&gt;bigdata&lt;/strong&gt;: the high-performance file system of the cluster based on GPFS.&lt;/li&gt;
	&lt;li&gt;&lt;strong&gt;nfs&lt;/strong&gt;: a loop-mounted EXT4 image mounted to the current compute node via NFS.&lt;/li&gt;
	&lt;li&gt;&lt;strong&gt;scr&lt;/strong&gt;: the local scratch file-system of the compute node.&lt;/li&gt;
	&lt;li&gt;&lt;strong&gt;tmpfs&lt;/strong&gt;: a virtual filesystem, physically located in the main memory of the compute node.&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;The trace files that were used to compile the referenced report are collected in this upload.&lt;/p&gt;</subfield>
