This will give a slightly different estimate than pryr::mem_used, which uses gc() internally. The purpose of this function is to allow continuous monitoring, external to the R session. Normally, this is run in a different session.

This will only work if the user has specified before running the spades call, set the interval, in seconds, that ps is run with options("spades.memoryUseInterval" = 0.5), will assess memory use every 0.5 seconds. The default is 0, meaning no interval, "off".

memoryUseThisSession(thisPid)

memoryUse(sim, max = TRUE)

Arguments

thisPid

Numeric or integer, the PID of the process. If omitted, it will be found with Sys.getpid()

sim

A completed simList

max

Logical. If TRUE, then it the return value will be summarized by module/event, showing the maximum memory used. If FALSE, then the raw memory used during each event will be shown.

Note

The suggested future and future.callr packages must be available.
