STAPL (the Standard Template Adaptive Parallel Library) is a framework for developing parallel programs in C++. It is designed to work on both shared and distributed memory parallel computers. Its core is a library of ISO Standard C++ components with interfaces similar to the ISO C++ STL. STAPL's goal is to allow the user to work at a high level of abstraction and hide many details specific to parallel programming, to allow a high degree of productivity, portability, and performance.

I have been directly involved in STAPL's development and over the years I have been responsible with several STAPL compoments. My main contributions are:

• Parallelizing STL containers - I have worked on the parallel infrastructure for containers, and developed the parallel vector container.
• A framework for parallelizing bulk order-commutative operations on trees - I have designed and implemented a parallel tree container in which threads can concurrently access and modify the tree.
• Automatic STL to STAPL translation - STL to STAPL code using C++ preprocessing - a pre-processing tool that translates STL interface into STAPL interface.
• Parallel algorithms- developed the parallel algorithms for several STL sequential algorithms, such as sort, inner-product and transform.
• Scheduling policies in STAPL - implemented static, dynamic and self-guided task schedulers.

I have also been involved in the ASCI project, a joint effort with the Nuclear Department and the national laboratories (Lawrence Livermore, Los Alamos and Sandia). My contribution was the development of STAPL executor for distributed systems, a communication/computation overlapping mechanism that schedules available tasks for execution as their needed data become available. I have also performed an locality optimization analysis using a field interleaving technique.
