At 102, execution of the Cache Line Demote instruction (e.g., CLDEMOTE) takes an address (e.g., 64 byte aligned) as an input, an uncore registers this address and the uncore opportunistically demotes content of a cache line associated with the address (e.g., cache line (M)) to ...
} \end{aligned}$$ The upper bounds to the response time with lower time complexity have been proposed in (Davis and Burns 2008; Baruah 2011; Bini et al. 2015; Nguyen et al. 2015). EDF-schedulability of task sets with implicit deadlines can be verified through the processor utilization ...
Cache-Aligned Data Buffers Context: Your application/driver caches packet buffers and buffer descriptors. Problem: You need to use the cache as effectively as possible. On some systems, the descriptors might be larger than a cache line. Solution: Allocate key data on cache line boundaries. This...
In this section, we evaluate our cache-line conflict simulator, C2Sim, using a typical x86_64 Linux server running CentOS 6.7 with two of Intel Xeon E5-2680 CPUs. We implement C2Sim on the top of Pin tool set [9]. For the baseline cache simulation, we set up the same configuration a...
2, the backside view of the DIMM (top of drawing) may be rotated down such that the notches, or keys, on the edges are aligned with the notches, or keys, on the edges of the front side view of the DIMM (bottom of drawing). In the depicted example, SDRAM chips 202 are arranged ...
The core part of C2Sim is similar to the algo- rithm used in cachegrind [1,11], which models SA caches, aligned and unaligned memory accesses and true LRU replacement policy on the top of a dynamic binary translator. In addition to the model found in cachegrind, we implement mechanisms ...
