in thread high array values

I don't know what that is, but certainly google, amazon, cern, the square kilometer array, no doubt NASA and the NSA and many other organisations have storage arrays that are that large; but none of them could construct a single, homogeneous, directly addressable entity of that magnitude.

(Theoretically, IBM's GPFS could handle it, but only if each element was no more than a single byte. I suspect that the same is true the other distributed filesystems.)

But even if they could, they could not be accessed from Perl, even via a tied interface, as internally, arrays use 32-bit indexes.
