For situations like these, you need to have already captured the data that can help you quickly get a sense of what's going wrong.
Yet many production environments don't have such data collection enabled, and some diagnostics have performance costs that are unsuitable for many production applications.
News and views from members of the Java team at Oracle Java’s code reflection API, developed in OpenJDK Project Babylon, opens a new path to targeting foreign programming models directly from Java—including GPUs.
This talk introduces the Heterogeneous Accelerator Toolkit (HAT), a Java parallel programming framework that accelerates modern workloads on specialised hardware through three core stages: reflect, transform, and accele…
We begin with the basics of code reflection and its key concepts, making the session accessible to developers new to the API.
