Many real-world problems involve dynamically changing data sets (including both discrete and continuous changes, e.g., as in motion). In our work, we develop algorithms that operate efficiently on dynamically changing data. Such algorithms can be very complex, especially if they are to be used in practice. We therefore also develop and apply general principles that bestow algorithm the ability to respond to changes to their data automatically.

Disentanglement refers to a memory property of many parallel algorithms: the memory allocated by concurrent computations remain independent and unknown to each other. This property is common and appears to be a fundamental one, probably because parallelism dictates some degree of separation. For example, all data-race-free programs, including purely functional programs, are disentangled. Many parallel programs with data races are also disentangled. Using disentanglement, it is possible to integrate scheduling and memory management to improve overall efficiency and performance of parallel programs, by solving key challenges due to communication costs that may appear inherent to parallelism. In this work, we study the theory and practice of disentanglement and apply it to develop a new compiler and run-time for the Parallel ML language, which extends the ML language.

## Parallel Computation

Usually motivated by increased parallelism in hardware and computing systems, parallelism research may be viewed as a natural evolution of computer science. I view sequential computing as a stunted phase in the history of computing and expect it to be short lived. Concretely put, sequential computing is P = 1, and is therefore a fundamentally uninteresting "edge case" on its own. Parallelism however is a hard problem. In my view solving it will require bringing together the two computationally equivalent but decidedly distinct theories of computing, by Church and Turing. This is what we do in our work. It addition to its relatively broad theoretical foundation, the work is also realized on modern hardware and languages (including smart languages such as the ML family and boring ones such as C/C++).

## Programming Languages

If you were told that the world would be destroyed tomorrow and that you could transmit a 50 some characters of knowledge to the future, what would your choose? I would choose to transmit the Lambda Calculus. If you don't know what that is and if you are a student of Computer Science and Mathematics, you must start learning about it now. So go do it. Then come back and enjoy the papers below, which are nearly all inspired by it.
