> Project Shenandoah:  An Ultra-low Pause time GC for OpenJDK
> 
> Overview:
> 
> I hereby propose the creation of the Shenandoah project with Christine
> H. Flood as the initial lead and the Hotspot group as the sponsoring
> group. [1]
> 
> Shenandoah is an ultra-low pause time garbage collector that reduces GC
> pause times by performing more garbage collection work concurrently
> with the running Java program. CMS and G1 both perform concurrent
> marking of live objects.  Shenandoah adds concurrent compaction.
> 
> Shenandoah has so far been developed as part of the IcedTea project:
> http://icedtea.classpath.org/wiki/Shenandoah
> 
> It has usable implementations for OpenJDK9 and OpenJDK8.
> 
> Initial authors/reviewers:
> Christine Flood (cflood at redhat.com)
> Roman Kennke (rkennke at redhat.com)
> 
> Christine H. Flood is a Principal Software Engineer at Red Hat.  
> She has a long history of implementing garbage collected programming
> languages at MIT, Symbolics, Sun Labs, and now Red Hat.  She helped 
> develop both G1 and the parallel collector.  A garbage collector 
> with concurrent evacuation is the obvious next step.
> 
> Roman Kennke is Principle Software Engineer at Red Hat, working on
> Shenandoah since two years now. Before this, he worked on Thermostat,
> and contributed to OpenJDK in several areas, most importantly the Zero
> and Shark ports, graphics, and ports to embedded platforms.
