B. Appendix: PCL Counters

Table 20 shows a summary of available PCL counters on certain machines. With the PCL interface of ADAPTOR, all of the available counters can be used to count the corresponding performance events for regions. The name of the PCL counter without the prefix PCL_ can be specified in the profile configuration file.

PCL supports also some composed counters, like PCL_MFLOPS, PCL_IPC, PCL_L2DCACHE_MISSRATE, and PCL_MEM_FP_RATIO. These counters are not supported via the ADAPTOR interface. But the same counters can be defined as own composed or derived counters.
