Traditional caches are automatic and cannot be controlled directly by software. A recent design called CLAM manages a cache using leases and lets a program specify these leases. The lease cache is mostly controlled by software. This paper extends CLAM to support multiple cores with private caches. It presents the hardware extensions to support cache coherence for data-race free (DRF) programs. CLAM can use either inclusive or exclusive caching for shared data. Its performance can be improved by two programming techniques: cache draining and reference privatization.
