I am not familiar with the Power Challenge system, but it probably
has big-endian IEEE representation. Intel PCs use little-endian IEEE
representation, so you will have to look into the IDL routines
SWAP_ENDIAN and BYTEORDER. If you will be using the data on both
platforms you should consider transferring the data to the XDR format.

With IDL for Linux you will get the same performance as for all
other Unixes. As far as I know, there are no restrictions due to Linux.
The current IDL for Windows version is used here as well, but I don't
use it myself.
