Well, it depends on what "register" means. The original meaning is the kind of storage with the smallest access latency. In CPUs, access to registers is faster than access to L1 caches, which in turn is faster than L2, etc. Small access latency means an expensive implementation, therefore ...
Hardware parallelism refers to the use of multiple processors, CPUs, or cores in a computer architecture to increase processing speed. It can be divided into two types: processor parallelism and memory parallelism. Processor parallelism involves having multiple nodes, CPUs, or cores, while memory par...
When SQL Server runs on a computer with more than one microprocessor/CPU or on SMP (a computer-architecture where two or more identical processors can connect to a single shared main memory and I/O and can perform the same functions. In case of multi-core processors, the SMP architecture ...
Many chapters make code changes in their applications to harness task or thread level parallelism with OpenMP. Chapter 17 drives home the meaning and value of being more “coarse-grained” in order to scale well. The challenges of making legacy code thread-safe are discussed in some detail in...
Specifically, if two (or more) keys are equivalent, meaning neither is less than the other, then these algorithms are free to reorder such keys in the process of sorting the data. In contrast, a stable sorting algorithm, such as stable sort and stable sort by key, preserves the relative ...
(e.g., the first 4 bytes are the value of hardware counter X, the next 4 bytes are the ID for the thread that generated the event, etc.). This description information allows the TID system to assign conceptual meaning to the raw trace information, and to extract performance measure ...
The instructions in the instruction cache are unpacked, meaning that the NOPs are explicitly present in the instructions. However, NOPs may be skipped by the instruction sequencing logic via an offset field in each operation. As illustrated in FIGS. 5A and 5B, the offset field 71 in each ...
(VMXB)228. Execution units212,214,216,218,220,222,224,226, and228are fully shared across both threads, meaning that execution units212,214,216,218,220,222,224,226, and228may receive instructions from either or both threads. The processor includes multiple register sets230,232,234,236,238,...
