In this paper, we propose an implementation of predefined MPI reduction operations utilizing AVX, AVX2 and AVX-512 intrinsics to provide vector-based reduction operation and to improve the time-to-solution of these predefined MPI reduction operations. With these optimizations, we achieve higher eficiency for local computa-tions, which directly ...

Do we multiply the rst number of the input by 24 or by 35? No one has speci ed an order for the variables, so we do not know how to calculate an output associated with a particular input.1 A di erent notation for V can clear this up; we can denote V itself as an ordered triple of numbers that reminds us what to do to each number from the input.

Fields. Taichi is a data-oriented programming language where fields are first-class citizens. Fields are essentially multi-dimensional arrays. An element of a field can be either a scalar (ti.field), (ti.Vector.field), or a matrix (ti.Matrix.field) Field elements are always accessed via the a[i, j, k] vector.

Summary: Multiplication of a matrix by a scalar In linear algebra, the word \scalar" simply means \number". For any matrix A = [a ij] m n and scalar we de ne A = [ a ij] m n = [a ij ] m n = A . For any matrices A, B of the same order and scalars ; we have: AT = ( A)T. A+ B = (A+ B) (distributivity). A+ ( 1)B = A B. ( A) = ( )A.
