Atmospheric Radiation Benchmark Source Codes

abstract

The radiation benchmarks compute long and short wave radiation values for a
grid-point atmospheric global climate model. These routines are perfectly
parallel codes, requiring communication only to set up the problem and gather
checksum results. There is also a dynamic load-balancing version of the
shortwave radiation code that insures an even distribution of work among
processing nodes at the expense of increased communications.

The source
code, written in fortran 77, has been designed to execute efficiently on
sequential, vector and mpp architectures with minimal updating to the source
code. The current version of the radiation benchmark has been successfully
executed on Sun and DEC Alpha workstations, the Cray C90 vector
processor, and Cray T3D, IBM SP2 and Intel Paragon MPP's.
