Class Da_cacheqn_retrieval

java.lang.Object

jline.api.da.Da_cacheqn_retrieval

public class Da_cacheqn_retrieval
extends Object

Decomposition-aggregation driver for a CLOSED integrated cache-queueing model whose Cache node has a delayed-hit retrieval system (Cache.setRetrievalSystem). Java port of matlab/src/api/da/da_cacheqn_retrieval.m. Adapts the integrated cacheqn decomposition: the cache is relabelled as a ClassSwitch (read -> hit / miss) and the finite-population delayed-hit coalescing is made to emerge from the closed AMVA by giving the retrieval (fetch) station a load-dependent COALESCING service rate lldscaling(k)=k/d(k), d(k)=n_eff*(1-(1-1/n_eff)^k), n_eff=nitems-totalcap. The distinct-fetch throughput saturates at 1/F and the coalescing benefit emerges from the finite population. LIMITATIONS (EXPERIMENTAL - see the MATLAB reference): hitprob/missprob are the true cache probabilities (hit=P(cached), miss=1-hit) and accurate; the delayed fraction is NOT recovered (delayedprob=0, folds into miss); the coalescing throughput benefit is captured only in direction and understated; single fetch station (single-backend) only.
