Folks I have come across an issue with gc() hogging the processor according to Rprof. Platform is Ubuntu 20.04 all up to date R version 4.3.1 libraries: survival, MASS, gtools and openxlsx. With default gc.auto options, the profiler notes the garbage collector as self.pct 99.39%. So I have tried switching it off using options(gc.auto=Inf) in the R session before running my program using

A question to all you R-gurus: Can R (or S-plus, for that matter) make efficient use of multiple Intel Processors running under Linux (within the same PC, not over a net)? With the release of the new 2.2 kernel, this would seem a interesting and cost-efficient way of boosting the computational power of Intel/Linux platforms when using R (or S-plus). Thanks for any wise words, Kenneth
