Dear all,
I am exploring ways to perform multiplication of a 90000 x 40000 matrix with
it's transpose.
As expected even a 40000 x 100 %*% 100x40000 didn't work on my desktop...
giving the error "Error: cannot allocate vector of length 1600000000"
However I am trying to run this on one node (64GB RAM; 2.60 GHz processor) of a
high performance computing cluster.
Appreciate if anyone has any comments on whether it's advisable to perform a
matrix multiplication of this size using R and also on any better ways to
handle this task.
Kind Regards,
Praveen.
