+# TITAN
+Is a tricky beast.  
+First its an AMD Interlagos based machine.
+The key is there are only one floating point unit per two cores.  So from a science perspective there are only 8 cores per node, not the sixteen listed.  Additionally your code needs to bind to just one core per pair.  See [Cray XK7 CPU info](https://www.olcf.ornl.gov/support/system-user-guides/titan-user-guide/#333)
