Finally, we see in Figure 1 that these schemes are hiding no more than half of the stall time due to instruction cache misses.
The code segment given in Figure 4(c) removes most cache misses and unnecessary prefetches, but further improvements are possible.
Figure 13 shows these graphs for the latex benchmark, and they confirm that the TRG-based conflict estimate is a more accurate predictor of actual cache misses.
This section presents a theoretical analysis of cache misses in left-looking and multifrontal sparse Cholesky factorization algorithms.
In [3], cache misses found in cc-NUMA multiprocessors are firstly classified in terms of the actions performed by directories to satisfy them, and then, it is proposed a novel node architecture that makes extensive use of on-processor-chip integration in order to reduce the latency of each one of the types of the classification.
01% of the local cache misses (averaged across all periods) is the desired block in the client caches, but the hints say otherwise.

We recommend, as a heuristic, choosing [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] because this value reduces the number of cache misses for the largest possible number of caches.
Hardware events such as cache misses, integer- and floating-point-unit stalls, exceptions, and interrupts all must be separated from run cycles to determine the actual type (read, write, execute) and size (word, halfword, byte) of the memory references made by a monitored processor.
When R is stored in column-major order, this technique drastically reduces the number of cache misses.
For example, threads with pending cache misses are not considered for cache/BTB access.
In the single-file tests, no cache misses or disk activity occur once the file has been brought into memory.
