SUMMARY:Energy-Based Accounting Model for Heterogeneous Supercomputers
DESCRIPTION:Workshop\n\nEnergy-Based Accounting Model for Heterogeneous Su
 percomputers\n\nDi Pietrantonio, Harris, Cytowski\n\nIn this paper we pres
 ent a new accounting model for heterogeneous supercomputers. An increasing
  number of supercomputing centers adopt heterogeneous architectures consis
 ting of CPUs and hardware accelerators for their systems. Accounting model
 s using the core hour as unit of measure are redefined to provide an appro
 priate charging rate based on the computing performance of different proce
 ssing elements, as well as their energy efficiency and purchase price. We 
 provide an overview of existing models and define a new model that, while 
 retaining the core hour as a fundamental concept, takes into account the i
 nterplay among resources such as CPUs and RAM, and that bases the GPU char
 ging rate on energy consumption.  This model, designed for the next superc
 omputer at the author's institution, has a lot of advantages compared to o
 ther models, introducing carbon footprint as a primary driver in determini
 ng the allocation of computational workflow on heterogeneous resources.\n\
