Fortran limit on array size on Linux?

[James_S_]

I'm helping a researcher who's trying to creat a 4-dimensional array of double precision numbers, with a total of ~200 million elements.

dimension vstore(1:4,0:4,5000000,2),fstore(0:4,5000000,2)

When he tries to compile this code with 'ifort adaptnew2.for', he gets this error:

compilation aborted for adaptnew2.for (code 1)

He's using ifort 11.0.074. This same error occurs on ia32 and intel64 systems, running on rebuild of RHEL 5.4.

Is this a limitation of the Intel Fortran compiler or a bug? When we decrease the dimensions of the array so that it's less than ~200 million, the code compiles.

The limit for statically allocated data with default memory model is 2GB, as you found. ALLOCATABLE arrays for Intel64 may be much larger.

Check the option "-mcmodel" of the compiler (man ifort?)
