SIMD
/sɪmˈdiː/
n. "Single Instruction Multiple Data parallel processing executing identical operation across vector lanes simultaneously."
GPGPU
/ˌdʒiː-piː-dʒiː-piː-juː/
n. “The use of a graphics processing unit to perform general-purpose computation.”
GPGPU, short for General-Purpose computing on Graphics Processing Units, refers to using a GPU to perform computations that are not limited to graphics rendering. While GPUs were originally designed to accelerate drawing pixels and polygons, their massively parallel architecture makes them exceptionally good at handling large-scale numerical and data-parallel workloads.
