Table 4 Runtime of OCMA for Singular Value Decomposition (SVD). Sample size N = 1 million. M is the number of selected genetic markers. The same machine described in the Tables 1 and 2 is used. Four threads are used in the test. Time is measured by wall-clock (instead of CPU time). The sign “/” indicates that the system does not allow the calculation to happen due to limited memory and swap spaces
