Mathemaica 5.2 are the 64 Bit an illusion !!!....?
Verified to fund both on Windows that on other OS : Mathematica 5.2 and the 64 bit are an illusion. You try on any system to create 4 numerical random matrixes of 10^4*10^4 elements (they should occupy around 4GB.Mathematica uses the packeds array in which every number of car occupies 8 bytes) but.... mathematica interrupts the calculation for lack of memory . A tool that it affirms to be to 64 bit doesn't have to do this...... or no? Thanks for the help Rob
