Reading from cache is significantly faster than reading from memory. Latency sensitive applications thus greatly benefit from having critical data and/or instructions in the cache.
Cache Pseudo-Locking (building on top of Intel's Cache Allocation Technology (CAT)) is a new feature being enabled in the Linux kernel that pseudo-locks a region of memory into a reserved portion of cache that only serves cache hits. The Cache Pseudo-Locked memory is made accessible to user space where an application can map it into its virtual address space and thus have a region of memory with reduced average read latency.

In this presentation, Reinette Chatre will introduce Cache Pseudo-Locking, demonstrate its benefits, and discuss the interfaces she has been working while enabling this feature in the Linux kernel.
