Memory requirement in `addprocs` and loading packages

General Usage
1

My cluster jobs keep getting killed due to execd enforced h_vmem limit. My script is below:

using Distributed
addprocs(8)

println("loaded 8 cores...")

@everywhere begin
    using DifferentialEquations
    using Thyrosim
    using DiffEqCallbacks
    using DiffEqParamEstim
    using SharedArrays
end

println("loaded all everywhere packages...")

using Optim

println("loaded Optim")

I do not even get loaded 8 cores.... On the cluster I requested 8 cores each with 3GB, so I’m pretty confused as to how I used more than 24GB. Any information is appreciated.
