1. X10 Future Plans & Discussion

2. X10 Development Roadmap Upcoming releases X10 2.2.3: August 2012
X10/Java interop
X : Late 2012
Mixed mode execution
Possibly extend scope of supported Java  X10 interop
No backwards incompatible changes with X10 2.2
Programs written against X spec will continue to work in future releases

3. Summary of X10/Java Interoperability for X10 2.2.3
Managed X10 only
X10  Java
use import statement to import a Java type into an X10 source file
just use the type normally
Create instances
Call methods, access fields
Implement it (if the imported type was an interface)
Helper class to allow easy access to Java arrays
Java  X10
Officially supported in this release
calling non-generic static X10 methods from Java (no escaping asyncs)
Many other scenarios will work in practice, but not ready to freeze code-generation strategy for generics yet (release-to-release compatibility)

4. Mixed Mode Execution
X10
Java
Place 0
Place 1
Place 34 …
Managed Place
Native Place
GPU
Program can run with mix of Native and Managed Places
In progress, but taking longer than expected…
