Enabling fair pricing on HPC systems with node sharing

Alex D. Breslow, Ananta Tiwari, Martin Schulz, Laura Carrington, Lingjia Tang, Jason Mars
2013 Proceedings of the International Conference for High Performance Computing, Networking, Storage and Analysis on - SC '13  
Co-location, where multiple jobs share compute nodes in large-scale HPC systems, has been shown to increase aggregate throughput and energy efficiency by 10 to 20%.  ...  However, system operators disallow co-location due to fair-pricing concerns, i.e., a pricing mechanism that considers performance interference from co-running jobs.  ...  To achieve these goals we have designed precise shuttering, an online co-runner interference masking approach.  ...

Exascale Computing Deployment Challenges [chapter]

Karim Djemame, Hamish Carr
2020 Lecture Notes in Computer Science  
This paper argues that this drives a once in a generation shift of computation, and that fundamentals of computer science therefore need to be re-examined.  ...  As part of this, we will argue that Exascale computing will require a significant degree of co-design and close attention to the economics underlying the challenges ahead.  ...  This will require a truly interdisciplinary effort to not only develop applicable techniques, but address the underlying models of both computational science and computer science.  ...
