While cache interference between workloads is in-tensively studied, non-interference caching problems suffered by individual workloads (e.g., those occur even in dedicated cache space) are largely ignored on cloud platforms. Webshared cache. Take the simple example of two concurrent processes writing to the same data block. The cost of their cache interference at each context switch is the re-loading of the cache block, which is very diﬀerent from the cost of par-allel access. In general, the interference manifests as cache warm-ups in the case of context switch. tamiya modelle 1970er jahre
