Abstract--Resizable caches can trade-off capacity for ac-
cess speed to dynamically match the needs of the workload.
In Simultaneous Multi-Threaded (SMT) cores, the caching
needs can vary greatly across the number of threads and
their characteristics, offering opportunities to dynamically
adjust cache resources to the workload. In this paper we
propose the use of resizable caches in order to improve
