Strided access

WebThis benchmark is expected to stress the file systems in more than one ways. First, access by each client to a dedicated tile (case (a)) requires effective strided-sequential I/O to non-contiguous regions in the file, resulting in a near-random access pattern (Section 2). Second, overlap in file accesses between clients in case (b) is expected ... http://thebeardsage.com/vector-optimization-stride/

WebJun 30, 2012 · When the two threads write the same 32 bit word in the same shared memory bank, then only one thread succeeds. Since on-chip memory is 64 KB (48 KB for shared memory and 16 KB for L1, or vice versa), and it is organized in 32 banks, I am assuming that each bank consists of 2 KB.

To realize this idea, GS-DRAM first maps the data of each cache line to different chips such that multiple values of a strided access pattern are mapped to different chips.
