Performance Question

2020-06-18 Thread Rana Alotaibi
Hi SystemML developers, I have been experimenting with SystemML lately. I found some interesting numbers when evaluating these two expressions: *t(M%*%N)* and *t(N)%*% t(M)* (The size of matrix M is 20Kx100 and N is 100x20K). The pipeline *t(N)%*% t(M) *drastically outperforms* t(M%*%N)*. -
