I am using "run on cloud" in PAT 2.9.1 and Latin Hypercube Sampling in the pursuit of running combinations of a range of values for the following variables - 4 different wall insulations, 4 different roof insulations, 6 values for window u-value, 5 values for window SHGC - which total to 19 different variables.
I ran a sample LHS with 1000 "number of samples". But I see only 33 different runs. I don't really understand what the number of samples is supposed to do. I am sure I am misunderstanding what it means and would love someone to enlighten me! 
I tried DOE algorithmic method, with the "number of samples = 19" which ran 400 cases, which are half of what I am expecting. What should be my Algorithm Settings to make all the cases run? The roof and ext wall measures didn't work. I have attached the PAT Project File if you wish to check it out.
I have another follow-up question posted a while ago. Take a look if you can, hopefully, you know the answer to it as well!- https://unmethours.com/question/43078/whats-the-best-way-to-unzip-large-set-of-compressed-folders/
I appreciate any and all help! Thanks
