Profiling Peak DRAM Use in R With Perl - Part 1

chrisarg.github.io

Another year, another opportunity for Perl to excel as a system’s language. Today I decided to take Perl for a (?)wild ride and use it to monitor peak physical DRAM use in a R script. Due to the multi-language nature of the post, there will be a lot of R code in the first part of the series; however, the code is self-explanatory, and should not be difficult to understand (the same applies to the Perl code for those coming from a R background). For those of you who would like to skip the R part (why?), jump straight to the end Part 1 to see the solution and then go to Part 2 for the details.
