SPEC MPI2007 Benchmark Description
Benchmark Name
121.pop2
Benchmark Author
Los Alamos National Laboratory (LANL)
Benchmark Program General Category
Parallel Ocean Program
Benchmark Description
The Parallel Ocean Program (POP) was developed at LANL under the sponsorship
of the Department of Energy's CHAMMP program, which brought massively
parallel computers to the realm of climate modeling. POP is a descendent
of the Bryan-Cox-Semtner class of ocean models first developed by Kirk Bryan
and Michael Cox [4] at the NOAA Geophysical Fluid Dynamics Laboratory
in Princeton, NJ in the late 1960s. POP had its origins in a version of the
model developed by Semtner and Chervin [18] [5].
MPI Usage
Uses Allreduce and waitall. Messages are typically 1024-4096 in size.
Input Description
pop_in is a text file in Fortran Namelist format which describes the input model. See section 3.1.2 Input/Output.
see http://climate.lanl.gov/Models/POP/UsersGuide.pdf
Output Description
The file pop2.out is a textual summary of the execution and the file pop_diag.your_id_here.00000101
is a trace of the execution.
