Description
X10 Release 2.6.1
HIGHLIGHTS OF THIS RELEASE
The focus of the X10 2.6.1 release is improvements to Resilient X10. Some highlights include:
- Significant improvements to the performance of resilient finish
- A new resilient store implemented in X10
- Improved standard library APIs for elasticity and non-shrinking recovery.
- Enhancements to the x10.util.resilient.iterative package to exploit elasticity to support non-shrinking recovery.
- Updating of all Resilient X10 sample programs and applications to showcase the improvements in Resilient X10.
LIMITATIONS OF THIS RELEASE
The size and index of arrays must be less than 2^31 with Managed X10. An attempt to allocate a longer array causes IllegalArgumentException.
The following features described in the 2.6 language manual do not currently work and may be fixed in the subsequent releases:
- Non-static type definitions as class or interface members (static type defs do work)
The constraint solver used by X10 typechecker is known to be incomplete for situations in which a constraint implies an infinite number of distinct constraints.
Additionally, the following features described in the language manual do not currently work with Native X10.
- Non-final generic instance methods
- Exception stack traces on Cygwin
The generated C++ code requires g++ 4.2 or better to be compiled; we do almost all of our testing against g++ 4.4.
- On Power/Linux and BG/Q, you may either use g++ 4.2 or better or xlC 11.1 or better.
