SIMD Series – GATHER/SCATTER OperationsAs we know, SIMD registers can communicate with the scalar domain (or more accurately, memory) using LOAD/STORE operations. The downside of these operations is that they only allow moving contiguous data elements in memory. However, in our code, we often need to access non-contiguous memory. This tutorial will explain the GATHER/SCATTER … Read more
Partition-based SIMD processing and its application in columnar database systems The Single Instruction Multiple Data (SIMD) paradigm is considered the core principle for optimizing query processing in columnar database systems. So far, only LOAD/STORE instructions are deemed efficient enough to achieve the expected acceleration, and it is believed that GATHER/SCATTER operations should be avoided as … Read more
Definition of Device Memory The Device memory type attributes define memory locations where an access to the location can cause side-effects, or where the value returned for a load can vary depending on the number of loads performed. Typically, the Device memory attributes are used for memory-mapped peripherals and similar locations. Device Memory Attributes: Gathering, … Read more
