Vega 3 Processor
The first 54-core chip designed and optimized for Java workloads. The Vega chip includes features not found in conventional processors, enabling a variety of optimizations that would otherwise be not possible. With support for features such as read and write barriers that help optimized garbage collection and object relocation, speculative locking to enable safe concurrent execution of code that would otherwise be serialized, and an instruction set designed for the needs of virtual machines, the Vega processor is designed to provide consistently high throughput to Java applications. In addition, Azul Vega Processors have enterprise grade Reliability, Availability and Serviceability (RAS) features designed into them, such as, predictive failure analysis for de-configuration and system memory chip-kill technology.
