Output from Parallel Model

Three types of output are to be expected from a production run of the PCCM2.1: model history output (binary), restart data (binary) and printed diagnostic information. There are a number of differences between the standard CCM2 output files and what can be expected in a MPP environment. These differences are largely due to the lack of standards ( defacto or otherwise) in parallel output operations. Each vendor provides a machine specific solution to the problem of efficient output and in the hope of providing a production quality implementation we have endeavored to take advantage of these solutions.
