Hi.

I have some memory problems with CPMD and the Linux/x86 implememtation.
When the program tries to allocate memory, the procedure returns a pointer
to the location of the memory allocated, that value that is returned is an
integer*4, meaning that it can only specify a maximum of 1Gb of memory.
Hence any problem that requires more than 1Gb per process fails.

Has anyone managed to allocate more than 1Gb of memory per process on an
x86 system, and if so, how they do it?

Many thanks,

Carmen
