Dear Cyrus, Have you tried running La.svd ; LAPACK only version (without R) via C/C++ or Fortran code? After all it can be a LAPACK issue and R-team has no control on that. Best, -m

No, Mehmet, I haven't tried that yet. I was hoping to find out if there was some other option. I have no experience using LAPACK directly. I have looked into RcppEigen and RcppArmadillo, but have not tested them yet. If there are no other options, I guess I will go down that path.
I tried it on a 64 bit R with 32GB of RAM. It exhausted those resources and started paging out into virtual memory. No error, but I killed the process.
