IDL will run, but all the 32-bit limitations still apply, and the performance is extremely poor (time_test3: 1.47s on 3.2GHz Xeon, 6.48s on 1.3GHz Altix). Keh-Cheng

This means that it should be installed only after copying the whole directory tree to the Altix... This is kind of weird, does RSI have some special reason not to sale its product to a 64 bits machine? I agree that it is not used by that much people yet but even so...!!! The performance seems to come from the fact that the 64 bits processor has a very slow 32 bits processor (less than 200 MHz, I heard) in it where 32 bits programs will run... A.
