AWE on NT was derived from the same work. There should soon be some discussion about it on lse-tech@lists.sourceforge.net or I can give you some more data... Worked for Oracle, should be good for large scientific apps, might work for other piggy server applications as well. gerrit In message , > : "Clif ford White" writes: > > We are working with a database that requires a large amount of memory > allocated by a single process. > This is on an Intel 32-bit platform. > We'd like to go > 3GB of memory per process. > Is this possible on a 32-bit machine?
