Table 5. Runtime of OCMA for a subset of singular values. Sample size N = 1 million. M, the number of selected genetic markers, is 5,000. K is the number of top SVs. The same machine described in the Table 1 and 2 is used. Four threads are used in the test. Time is measured by wall-clock (instead of CPU time).
