[mpich-discuss] romio large array

I have an array which I like to read into a single process it's 
1024x1024x512x4, 2GB, but when I try to read it I get the error

Invalid argument, error stack:
MPI_FILE_READ_ALL(105): Invalid count argument

In this case count is 536870912 and data type is MPI_FLOAT. Is it 
possible to read the 2GB array on a single process ? The system has 16 
GB per node.

Thanks
Burlen
