`TensorOperations.jl` does not seem to support 32-bit Julia?

I tried to install the package on a 32-bit Julia and got the precompile error message:

ERROR: LoadError: InexactError: trunc(Int32, 17001435136)

Can I infer correctly that you have 64 GB of memory on your machine? But you still use a 32-bit version of Julia. How does that work exactly?

[frankwswang]

I only have 16 GB of memory on my machine. My system is a 64-bit Windows, but I wanted to try out the 32-bit Julia version.

[Jutho]

Oh right, I misinterpreted one line of my code (which could be improved). Still, 32bit would theoretically only allow 4GB of memory. Can you confirm that typeof(Sys.total_memory()) is UInt64 despite using 32-bit Julia?

Yes. I can confirm that on my machine, even when running a 32-bit Julia, typeof(Sys.total_memory()) is still UInt64.

[Jutho]

Ok, to fully support this, I would need to change a number of Int to Int32 variables (struct fields) in both LRUCache.jl and TensorOperations.jl

Since I don't have a 32-bit julia installation at hand, what is the value of something like typeof(sizeof(randn(1,1))). Perhaps I should just change everything to Int64 explicitly to be on the safe side.

For typeof(sizeof(randn(1,1))) it's Int32.
