The prefetch-on-miss algorithm simply initiates a prefetch for block b + i whenever an access for block b results in a cache miss
5 shows that a TRG yields a stronger linear relationship between conflict-metric values and cache miss
rates than does a WCG.
Meanwhile, high cache miss
rate depends on the size of the cache and the efficiency of the replacement policy engaged in the cache management.
Two of the most important of these issues are, first, the cost in terms of the hardware overhead that the use of directories implies, and, second, the increased distance to memory, which is the reason for the higher cache miss
latencies that are currently being observed in cc-NUMA architectures.
A client handles a local cache miss
by retrieving the missing block from the lower levels of the storage hierarchy.
Tables V and VI and Figures 29 and 30 show the effect of SCBP on program size, branch misprediction rate, and cache miss
A common example is a cache hit which, unlike a cache miss
, typically does not require any updates to a cache's contents.
Additionally, MemMax Scheduler adds support for XOR burst sequences, which minimizes cache miss
latency for DDR3 DRAMs and is configurable on a per thread basis allowing chip architects to perform delicate QoS trade-offs between memory utilization and latency minimization.
The former approach restricts cache hit ratio while the latter increases the size of a routing table, cache miss
penalty and update overhead.
The address traces generated by our Gauss-Seidel execution was fed into this profiler which in turn modelled the corresponding cache operation to give out cache miss
Average reductions on the cache miss
rate between 30% and 60% and peak reductions greater than 200% are obtained.
A reduced cache size causes higher cache miss
rates, increasing the number of disk accesses and reducing throughput.
Those relationships are used to generate a set of equations--called the Cache Miss
Equations (or CM equations or CMEs)--representing all the cache misses
in a loop nest.
More important, they must provide low latency, since in the case of a cache miss
, the processor is stalled until the miss is satisfied.
Since the resource cost as well as the response delay in the case of cache hit is negligible compared with that of cache miss
, we only consider the cache miss
requests in our analytical framework.
