Scripts to run Benchmarks between some linear algebra libraries

Clone this repo to your local machine and run using bin/run from the root directory.

Benchmarks prepared to run on Mac OSX.

Turn off multi-threading in your machine from Instruments -> Preferences -> CPUs and set the number of threads to 1.

You may set the parameters for the tests in test_parameters.txt.

If you already have Armadillo installed, supply the path to the Armadillo includes using ARMA. If you already have Eigen installed (> Eigen3), you may supply the include folder to Eigen using EIGEN.

e.g.

ARMA=/path/to/arma EIGEN=path/to/include bin/run

Note: Will install homebrew and wget to your machine to download the dependencies

The types of Tests

Vector addition

e = a + b + c + d

Parameters:

• L: Length of vectors

Element-wise Matrix Operations

      /  A + B      \
X = E | ------- - D |
      \    C        /

Parameters:

• M: Number of rows of all the matrices
• N: Number of columns of all the matrices

Note: The multiplication is element-wise multiplication

GEMM Comprehension

E += (A + B) * (C - D)

Parameters:

• M: Number of rows of A, B, and E
• N: Number of columns A and B and number of rows of C and D
• K: Number of columns of C, D, and E

Chained GEMM

E = W * X * Y * Z

Parameters:

• A: Number of rows of W, and X, number of columns of W
• B: Number of columns X, and number of rows of Y
• C: Number of columns Y, number of rows of Z
• D: Number of columns of Z
