comment Why does MemoryConstrained have an upper limit on the constraint?
When I posted the code above it left out the * from 64-bit. That will not work. Maybe you can just include that code (or the better version with $SystemWordLength) as a sidenote in your answer for others who may need. :)

Hmm nice! I will use that instead.

To run on both systems: MemoryLimit[]:=If[StringMatchQ[$System,"64-bit"],8*1024^3,1024^3]. 8 GB on the node and 1 GB on my computer.

Ok, I tested the code on the computer I want to run the script and It worked. It is 64 bits. Thank you.

Yes, you were right. I'll unaccept and wait a little more. But yours seems very promissing. Thanks again.

It's an alternative, timed between my first and second approaches.

Corrected there, thanks! Your code seems faster in all situations after I corrected the bug.
