    35As we move towards the exascale-era, HPC systems are becoming increasingly complex with, for example, co-processors (eg, GPUs, Intel Xeon Phis), Non-uniform memory-access (NUMA) nodes, and various network structures, as well as the trend for increasing numbers of cores with decreasing speeds and decreasing memory per core. This makes it challenging to predict the performance of real applications on new and forthcoming machines.

    911In this case a performance model encapsulates information about the software and hardware to make a prediction of elapsed wallclock run time for a given scenario.
