Yes no worries, although I'm not sure it'll be much use as it is fairly
specialised to the types I work with:
function checkRAMUsage!(d::FinList)
if sizeof(d) > 7000000000
println("FinList too large. Removing HF data and triggering garbage
collection.")
deleteatFinHF!(d)
end
#gc() #Currently this line doesn't seem to do anything so it is
commented out
return(true)
end
FinList is a type I made to store all the financial data I've read in to
RAM, so simply testing the size of d in the code above gives a pretty
accurate measure of how much RAM I'm currently using. I'm not aware of a
general function to check how much RAM julia is currently using, but you
could get a pretty god idea by looping over all the variables in workspace
and adding up the output of sizeof on each of them. My function
deleteatFinHF! just goes through the FinList and empties all the arrays of
high-frequency data (which is invariably what is taking up most of the RAM
in the work I do).
