SUMMARYThis paper describes CATAPULTS (Creating And Testing APplication-specific User Level Thread Schedulers), a domain-specific language for creating and testing application-specific user-level thread schedulers. Using a domain-specific language to write user-level thread schedulers provides three advantages. First, doing so modularizes the thread scheduler, making it easy to plug in and experiment with different thread scheduling strategies. Second, using a domain-specific language for scheduling code helps prevent several of the common programming mistakes that are easy to make when developing thread schedulers. Finally, the CATAPULTS translator has multiple backends that generate code for different languages and libraries. This makes it easy to prototype an application in a high-level language and then later port it to a low-level language; the CATAPULTS translator will take care of generating the appropriate code for both the prototype and the final version of the program from a single scheduler specification. This paper describes how we have used CATAPULTS to improve the performance of two important and representative Internet server applications.

SUMMARYThis paper describes our work to improve the performance of distributed applications. We aim at certain application characteristics such as balancing load, allowing separately written applications to work better together, allowing a distributed application to adapt its behavior in more flexible ways, and so on. Our approach is to write application-specific schedulers, which can access the global state of the application in making scheduling decisions. To achieve this goal, we extended our earlier work on CATAPULTS (Creating And Testing APplication-specific User Level Thread Schedulers), a domain-specific language for creating and testing application-specific user-level thread schedulers, to distributed applications by adding 'master schedulers' for dealing with the distributed parts of applications. This paper presents our design of, experimentation with, and implementation of distributed CATAPULTS. This paper presents several realistic examples to measure the feasibility of this approach, specifically: a website application, an embedded application, and load balancing. Each example has a scheduling goal for which we developed a customized scheduler. We measured the performance with and without the customized scheduler. The customized scheduler for each example was fairly straightforward to develop and each achieved its scheduling goal. Copyright
