One of the largest challenges in client-side caching in extremely large-scale environments is consistency and coherency. By handling a user-space cache, we can offer applications much closer control over our client-side cache and scale the cache with the size of the compute resources (i.e. compute nodes). Cache data is shared among each compute node analagous to a traditional shared memory machine. Our approach to maintaining the integrity of the distributed cache turns out to be quite scalable and offers potentially sizable performance gains. 1.
