Is it maybe that the default R binary on Ubuntu hasn't been optimized? Have you tried building R from source on Ubuntu?

- zac_hudson 4y agoI've personally tried building the software I need for source before, but getting all the BLAS/LAPACK and MPI libraries with it has been annoying and time consuming. Your supercomputer cluster may offer pre-built optimized binaries for your CPU. For mine, I've been using prebuilt software offered by compute canada over CVMFS[1]. I assume something similar is available for wherever you get your supercomputing resources from. 1. https://docs.alliancecan.ca/wiki/Accessing_CVMFS https://docs.alliancecan.ca/wiki/Accessing_CVMFS
