 * InfiniBand component 

 * 

 * Tested version of OFED: 1.4

 *

 * @brief

 *  This file has the source code for a component that enables PAPI-C to 

 *  access hardware monitoring counters for InfiniBand devices through the  

 *  OFED library. Since a new interface was introduced with OFED version 1.4 

 *  (released Dec 2008), the current InfiniBand component does not support 

 *  OFED versions < 1.4.
