The combination of the high bandwidth demands from the processing cores, together with the high cost of cache misses
, makes this issue especially critical for future chip-multiprocessors.
As the mean query generate time increases the number of uplink requests decreases because there will be less number of cache misses
The coverage factor is the fraction of original cache misses
that are prefetched.
Such cache misses
are known as cold start or compulsory misses.
One possibility is to decrease NB in order to decrease the number of cache misses
in an attempt to fit the submatrix into the cache.
Our procedure-placement technique improves the instruction cache mapping to reduce the number of instruction cache misses
in one or multiple levels of instruction cache.
0 latencies are of cache misses
below Sequent's one-in-five or one-in-ten but have been deliberately kept high enough for students to be able to test and examine behavior clearly.
In case of cache misses
, the caches access main memory through a 64-bit high-performance bus similar to that of the MC88110 .
When the code is executed, it is there each and every time - eliminating cache misses
and producing a consistent response time.
The cache server queries the authoritative server for the cache misses
DNS question, meanwhile maintains its status as unanswered in a waiting queue.
This leads to performance bottlenecks including Layer 1 / Layer 2 CPU cache misses
and pipeline mispredictions.
Direct cache-miss measurements indicate that the difference in performance is largely due to differences in the number of level-2 cache misses
that the two algorithms generate.
Then, in Section 3 we depict some important research efforts for accelerating cache misses
in these architectures.
Local cache misses
that hit in the server cache avoid expensive disk accesses.
Transforming a control-flow graph into a linear sequence of instructions is called the code layout problem; algorithms that attack code layout attempt to reduce cache misses
or pipeline stalls in the program by changing the order of basic blocks or procedures [Calder and Grunwald 1994; Hwu and Chang 1989; McFarling 1993; Pettis and Hansen 1990; Torellas et al.
