The LINPACK benchmark is a test for rating the performance of a computer on a simple linear algebra problem. What do you usually put for the inputs?
Specifically, leading dimension of array: The documentation says:
"The leading dimension must be no less than the number of equations. Experience has shown that the best performance for a given problem size is obtained when the leading dimension is set to the nearest odd multiple of 8 (16 for Intel(R) Itanium(R) 2 processors) equal to or larger than the number of equations (divisible by 8 but not by 16, or divisible by 16 but not 32 for Intel(R) Itanium(R) 2 processors)."
Why is that the case for best performance?
