Vector Optimization Gather Scatter The Beard Sage The primary mechanism for supporting sparse matrices is gather scatter operations using index vectors. the goal of such operations is to support moving between a compressed representation (i.e., zeros are not included) and normal representation (i.e., the zeros are included) of a sparse matrix. Vector processors (and some simd units in cpus) have hardware support for gather and scatter operations, as do many input output systems, allowing large data sets to be transferred to main memory more rapidly.
Vector Optimization Gather Scatter The Beard Sage Compiler can guide the programmer to improve code to make them vectorizable. sparse matrices and non strided memory locations can be accessed by vectors using gather scatter operation. i blog about computer science related material at the graduate level. Performance can thus be improved by revising code or by giving hints to the compiler when it’s ok to assume independence between operations (scatter gather). both compiler and programmer give hints to each other on how to improve performance. Sparse matrices and non strided memory locations can be accessed by vectors using gather scatter operation. continue reading →.

The primary mechanism for supporting sparse matrices is gather scatter operations using index vectors. the goal of such operations is to support moving between a compressed representation (i.e., zeros are not included) and normal representation (i.e., the zeros are included) of a sparse matrix. Gather and scatter operation is controlled by an index vector to select rows or columns from a, b, c or d matrices. suppose, all matrices are column major. Vector processors initially developed for super computing applications, today important for multimedia. vector processors have high level operations that work on linear arrays of numbers: "vectors". Since the estimation and optimization techniques are similar on the scatter and the gather operations, we describe the techniques for the scatter in detail, and present those for the gather in brief. Usefully interacting with other threads requires atomicity at a minimum, so i think that implies gather scatter are per element atomic, even if the operation pseudocode shouldn't be taken that way.
