-------------------------------------
Hey Mikalai,
I looked at your code closely today. Please delete all unnecessary classes and
try to rewrite SpMV and SpMVTest programs.
{code}
/**
* Simple test.
* multiplying
* [1 0 6 0] [2] [38]
* [0 4 0 0] * [3] = [12]
* [0 2 3 0] [6] [24]
* [3 0 0 5] [1] [11]
*/
//@Test
public void testSpMVBasic() {
Path m = generateRandomMatrix(); // 1. generate 4x4 matrix
Path v = generateRandomMatrix(); // 2. generate 4x1 matrix (column vector)
SpMV.main(m, v, TMP_OUT); // 2. job configuration
verifyResult(TMP_OUT);
}
