Timeline to a Predicament – APIs & Growing Memory Complexity

Paper Presentation

•Problem

–The simple bifurcated memory hierarchy of the 1950s has evolved into a much more complex hierarchy while interfaces have remained relatively fixed.

–At the same time, computer architectures have evolved from single nodes to large parallel systems.

•Solution

–Update the interface to support a prescriptive (directive based) approach.

–Manage dynamic placement & movement with a smart distributed runtime system

•Impact

–Enable domain scientist to focus on their specialty rather than requiring them to become experts on memory architectures.

–Enable target independent programmability & target independent performance.
