Hosted by OOPSLA 2005 Preface

As mainstream hardware moves to multicore processors, programmers will be forced to write multithreaded programs in order to achieve high performance. One thing seems clear: mainstream programmers cannot use today’s abstractions of locks, condition variables, semaphores, and barriers to develop scalable parallel software effectively. This workshop addresses the problem of how best to express synchronization and concurrency in object-oriented multithreaded programming environments. This workshop brings together researchers working on different parts of this problem, including: frameworks and libraries for concurrent object-oriented programming, patterns in concurrent software, tools for detecting concurrencyrelated bugs, new programming abstractions, and new directions for low-level support from the operating system and hardware. SCOOL ’05 builds on the success of last year’s workshop on Concurrency and Synchronization in Java Programs (CSJP) to understand how these pieces fit together, and to define the research challenges that will adapt today’s object-oriented programming languages for tomorrow’s hardware. We thank to the members of the program committee for their thoughtful and timely reviews of the submissions.
