The second day of the technical tracks started with a keynote by Markus Püschel. He is not the typical programming language researcher you meet at OOPSLA, but he does research in automatic optimization of programs. In his keynote, he showed a number of examples how to get the best performance for a given algorithm out of a particular processor architecture. Today’s compilers are still not up to the task, and will probably never be up to it. Given a naïve implementation, hand-optimized C code can have 10x speedup when dependencies are made explicit, and the compiler knows that no aliasing can happen. He was then discussing how that can be approached in an automated way, and was also thinking about what programming languages could do.
The first day of the technical tracks including OOPSLA started with a keynote by Ivan Sutherland titled The Sequential Prison. His main point was that the way we think and the way we build machines and software is based on sequential concepts. The words we use to communicate and express ourselves are often of a very sequential nature. His examples included: call, do, repeat, program, and instruction. Other examples that shape and restrict our way of thinking are for instance basic data structures and concepts like strings (character sequences). However, we also use words that enable thinking about concurrency and parallelism much better. His examples for these included: configure, pipeline, connect, channel, network, and path.
My second workshop paper got published at the ACM Digital Library. This is actually only an abstract, but nonetheless, it might be interesting for people looking into the design of virtual machines and especially bytecodes/intermediate languages.
