SLICC: Self-Assembly of Instruction Cache Collectives for OLTP Workloads

Online Transaction Processing (OLTP) is at the core of many data center applications. OLTP workloads are known to have large instruction footprints that foil existing L1 instruction caches resulting in poor overall performance. Prefetching can reduce the impact of such instruction cache miss stalls; however, state-of-the-art solutions require large dedicated hardware tables on the order of 40KB in size. SLICC is a programmer transparent, low cost technique to minimize instruction cache misses when executing OLTP workloads. SLICC migrate threads, spreading their instruction footprint over several L1 caches.
