Explore the Vector API for Java in this 46-minute conference talk. Dive into the project's goals, terminology, and motivation behind this new abstraction for vectors in Java. Learn about code snippets as a substrate, primitive implementation, and machine instruction binding. Examine the API structure, including fully realized expressiveness and higher-order components. Discover how to construct kernels using the Vector API and understand the challenges faced in creating an idiomatic design. Gain insights into statically typed wrappers, expression binding to method handles, and the concept of an embedded domain-specific language (EDSL). Compare the approach with expression trees and get a glimpse of ongoing work in this exciting area of Java development.
