Table 2.

Speed performance of GLM with and without using block matrix multiplication strategy

No. of covariates	Time (s)
No. of covariates	Without using block matrix multiplication strategy	With using block matrix multiplication strategy
0	1012	597
3	2853	614
5	4908	623
10	10,837	681

Note: 0, 3, 5, and 10 covariates are added in both PLINK v1.9 and rMVP for testing speed of GLM with and without using block matrix multiplication strategy, respectively. A dataset including 16,000 samples with 1,600,000 SNPs is generated by PLINK software and used for test. All tests are performed using single thread. GLM, general linear model.
