associative cache, a common choice for later implementations. The source code of tsrm_realpath_r details the procedure. Additionally, there is a problem that virtual-to-physical mappings can change, which would require flushing cache lines, as the VAs would no longer be valid.

Shared highest-level cache, which is called before accessing memory, is usually referred to as the last level cache (LLC). Loop nest optimization largely coming from the High Performance Computing (HPC) community. 44 45 For a simple, direct-mapped design fast sram can be used. Victim cache edit A victim cache is a cache used to hold blocks evicted from a CPU cache upon replacement. Level 2 and above) have progressively larger numbers of blocks, larger block size, more blocks in a set, and relatively longer access times, but are still much faster than main memory.
(The Cray-1 did, however, have an instruction cache.) Multi-core chips edit When considering a chip with multiple cores, there is a question of whether the caches should be shared or local to each core. 4 The data cache is usually organized as a hierarchy of more cache levels (L1, L2, etc.; see also multi-level caches below).
