  abstract= "Cache utilisation is often very poor in multithreaded
     applications, due to the loss of data access locality
     incurred by frequent context switching. This problem is
     compounded on shared memory multiprocessors when dynamic
     load balancing is introduced and thread migration disrupts
     cache content. In this paper, we present a technique, which
     we refer to as *batching*, for reducing the negative impact
     of fine grain multithreading on cache performance. Prototype
     schedulers running on uniprocessors and shared memory
     multiprocessors are described, and finally experimental
     results which illustrate the improvements observed after
     applying our techniques are presented."
