Survey of Memory Management Techniques for HPC and Cloud Computing

Anna Pupykina, Giovanni Agosta
2019 IEEE Access  
The emergence of new classes of HPC applications and usage models, such as real-time HPC and cloud HPC, coupled with the increasingly heterogeneous nature of HPC architectures, requires a renewed investigation  ...  As such, the typical practice of reserving a subset of the supercomputer to a single application becomes less attractive, leading to the exploration of cloud technologies.  ...  This solution is convenient to find local resources and to apply recursive top-down placement algorithms while correctly exposing the topology of these new architectures.  ...
