I had been playing around with update-alternatives to swap between the three, but just in case this was causing issues I've used apt to purge all three and do a clean install for each one. However, the end result is the same for all three circumstances - both of the arma chol calls fail but the R chol works and none of the eigen results match. Additionally, I am regularly seeing circumstances where one of the arma eigen calls runs, I can see activity across all 4 cores when using openblas or atlas, and then a hang where one core stays pegged at 100% but nothing appears to happen until I kill the process. I am still at a loss as to why R is working fine while the arma calls fail. -Colin. _______________________________________________ Rcpp-devel mailing list [email protected] https://lists.r-forge.r-project.org/cgi-bin/mailman/listinfo/rcpp-devel
