	* ~~Five small X-Stack~~ projects ~~(DynAX, X-Tune, GVR, Corvette, and SLEEC) were also selected, as they offered exceptional solutions to one or more of the problem areas.~~		* The complete set of current projects is shown here:

	* One additional X-Stack project (PIPER) was selected to start in 2013, as it offered a very comprehensive solution for Exascale tools.		* [[File:SoftwareStack.jpg]]

	* The X-Stack Program was created to support research that targets significant advances in programming models, languages, compilers, runtime systems and tools. The expected results of this program are complete solutions to the system software stack for Exascale computing platforms (X-Stack)which address fundamental challenges identified in the [http://science.energy.gov/ascr/research/computer-science/programming-challenges-workshop/ ASCR Exascale Programming Challenges Workshop], captured in the [http://science.energy.gov/~/media/ascr/pdf/program-documents/docs/ProgrammingChallengesWorkshopReport.pdf workshop report], as well as the ones identified in the [http://science.energy.gov/ascr/research/computer-science/exascale-tools-workshop/ ASCR Exascale Tools Workshop], captured in the [http://science.energy.gov/~/media/ascr/pdf/research/cs/Exascale%20Workshop/Exascale_Tools_Workshop_Report.pdf workshop report]. Solutions being researched involve radically new approaches to programming Exascale applications and algorithms and will demonstrate the viability of such solutions in a broad high performance programming context and will enable automatic semantics and performance preserving transformations of applications (possibly with users in the loop).		* The X-Stack Program was created to support research that targets significant advances in programming models, languages, compilers, runtime systems and tools.
