[R] has anybody used gpuCor?

I tried to calculate the pairwise pearson correlation of the column vector of a matrix of 20,000 columns using the gpuCor fucntion from the package gputools, and compare the speed with the ordinary cor function. The gpuCor is supposed to be much faster than cor. But I found that the ordinay cor is

[R] Why was my R process killed spontaneously?

I tried to use gpuCor function in the gputools package of R to calcuate the pairwise correlations of a matrix of 40,000 columns. Becuase there would be memory issues if I use the whole matrix at a time, I splitted the matrix into submatrix of 10,000 columns and then calculate the pairwise correlat
