Hello,

I am trying to find parameters that make my model work using brute force. To do this I need to run my model many times varying the parameters each time. It works when I do it without multithreading but I want to run many more trials.

I’ve been reading the Parallel Computing doc as well as these forums so I know I need to have an individual rand for each thread but I am not sure how to do this. Julia is my first computing language and (I think) I have a basic understanding of programming.

```
using Random; import Future
function parameter_search2()
for i in 1:1000000
# Threads.@threads for i in 1:1000000 # this one
# @threads for i in 1:1000000 # or this one?
bioS = sol[end] # this is generated once, outside of this function
target_species = 42
catch_max2 = rand(Uniform(0,1)) # should it be rand([threadid()Uniform(0,1)]) ?
scaling2 = rand(Uniform(0,1))
maintenance2 = rand(Uniform(0,0.5))
P_catch2 = rand(Uniform(0,0.5))
μ2 = rand(Uniform(0,0.5))
# after this point I run a differential equation using these random value inputs;
# and then println when a criteria is reached
end
```

Any advice or example is appreciated.
