The Last Frontier in Java Performance: Remove the Garbage Collector

by Abraham Marín Pérez on  Mar 01, 2017 11

A new JEP draft has been filed to create a no-op garbage collector: a GC that doesn't actually reclaim memory. This is aimed at aiding JVM implementers and researches and, to a lesser extent, ultra-performant applications that generate little to no garbage. If the JEP goes ahead, the new GC would be available together with the existing ones, and would have no effect unless explicitly activated.

LLD, LLVM’s New Linker, Coming to LLVM 4

by Sergio De Simone on  Feb 21, 2017

LLD, which touts great performance improvements over GCC ld, will be included in LLVM 4 rc1 and enabled by default. Although the new linker is already able to build a running FreeBSD/amd64 base system, its inclusion in LLVM is still experimental and could be set back in rc2 if it causes problems.

MIT Extended LLVM IR to Enable Better Optimization of Parallel Programs

by Sergio De Simone on  Feb 06, 2017

Researchers at MIT have been working on a fork of LLVM to explore a new approach to optimizing parallel code by embedding fork-join parallelism directly into the compiler’s intermediate representation (IR). This, the researchers maintain, makes it possible to leverage most of the IR-level serial optimizations for parallel programs.

Java 9 Enters First Bug Fixing Round

by Abraham Marín Pérez on  Jan 31, 2017 4

Java 9 is now officially feature complete, meaning the first bug-fixing phase has started. HTTP/2 Client didn't make it on time for the deadline and has been downgraded to an incubating feature. Since the objective now is to prepare Java 9 for general availability in July, it is very unlikely that any new JEP will be added at this point.

JVMs Across the Data Center and Twitter's JDK

The Twitter Sponsored Solutions track at QConSF2016 features an engineering talk on JVMs Across the Data Center and unveils an in-house OpenJDK fork, the Twitter-JDK, with noted potential open-sourcing or release to broader public.

Using Cloud Sandboxes to “Shift Left” Testing within Production-Like Environments

by Daniel Bryant on  Oct 16, 2016

InfoQ recently sat down with Joan Wrabetz, CTO at Quali, and discussed the role ‘cloud sandboxes’ can take within the modern software development lifecycle (SDLC). Cloud sandboxes allow a user to create and publish replicas of infrastructure and application configurations for on-demand usage. The primary use cases for cloud sandboxes include development and quality assurance testing.
