Efficient implementation of sorting on multi-core SIMD … WebJun 21, 2024 · Since the title mentioned GPU-friendliness: GPUs are built all around scatter/gather memory accesses. The actual performance of memory accesses of course still depends on locality. The first load in a parallel binary search will be fast, since all threads will load the same element, later loads can get progressively worse. tavanate
How L1 and L2 CPU Caches Work, and Why They
WebAug 16, 2024 · 32KB can be divided into 32KB / 64 = 512 Cache Lines. Because there are 8-Way, there are 512 / 8 = 64 Sets. So each set has 8 x 64 = 512 Bytes of cache, and each Way has 4KB of cache. Today’s operating systems divide physical memory into 4KB pages to be read, each with exactly 64 Cache Lines. WebWhenever an instance of Data is allocated, it will be at the beginning of a cache line. The downside is that the effective size of the structure will be rounded up to the nearest multiple of 64 bytes. This has to be done so that, e.g., when allocating an array of Data, not just the first element is properly aligned. #Structure Alignment This issue becomes more … tavan autoadeziv
