How Much SSD Is Useful for Resilience in Supercomputers
Aiman Fang, Andrew A. Chien · 2015
We consider the use of non-volatile memories in the form of burst buffers for resilience in supercomputers. Their cost and limited lifetime demand effective use and appropriate provisioning. We develop an analytic model for the behavior of workloads on systems with burst buffers, and use it to explore questions of cost-effective provisioning, and mission-directed allocation of burst-buffer (SSD) lifetime.
