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
