Popis: This WhitePaper explores the possible benefit of using OpenACC performance tuning directives, comparing the two prevalent implementations of the standard, CAPS and PGI. The performance of the default generated code along with the impact of the gang and vector parameters is evaluated through a matrix-matrix multiplication an a Classical Gram-Schmidt orthonormalization. Additonally, the impact in the context of a change in the hardware is assessed.
