Max Matrix Size

Hello,

I am running a 32 bit version of Mathematica 7 on my Mac. I was wondering if there is an upper limit on the size of a matrix/tensor that Mathematica can create.

Is it simply limited by the available memory? Is there a time limit for generating the matrix?

Could mathematica complete a task that should take 12 hours (extrapolating based on current speed)?

Thanks.

I think the only limit will be our patience and computer memory. For example, the following is the timing on my OS 10.4 iBook.

Clear["Global`*"];
m[n_]:= Table[{RandomInteger[{0,9}],RandomInteger[{0,9}],{i,1,n}];
#[[1]]& /@ {Timing[m[#];]& /@{10^1, 10^3, 10^3} }
