FluTE Synthetic Ecosystems for USA

Data files A set of 3 data files needs to be in the same directory as the executable to specify a population for FluTE. The file names consist of a prefix (e.g., "seattle") followed by a suffix. *-tracts.dat - Tract populations and locations, from http://www.census.gov/geo/www/cenpop/cntpop2k.html. The columns in this comma-delimited file are: state FIPS code, county FIPS code, tract FIPS code, tract population, tract longitude, and tract latitude. *-wf.dat - Tract-to-tract workerflow, extracted from stp64.us from Census 2000 Special Tabulation Product 64: Census tract of work by census tract of residence 2000. For the US-level data. Commutes over 100 miles were eliminated from the data. The columns in this space- delimited file are: home state FIPS code, home county FIPS code, home tract FIPS code, work state FIPS code, work county FIPS code, work tract FIPS code, and number of workers. *-employment.dat - The number of employed working-age adults and the total number of working-age adults, from the Census Summary File 3 (SF3, Table PCT35). The columns in this space-delimited file are: state FIPS code, county FIPS code, tract FIPS code, number of employed 20-64 year olds, and the total number of working-age individuals (19-64 year olds). This sample population is: usa - The continental United States, based on the 2000 US Census. Note that the "wf" files are split into 49 separate files, one for each state and one for Washington, D.C. The wf file would be too large as a single file. When mpiflute does not find "usa-wf.dat", it looks for "usa-wf-?.dat", where "?" is the state FIPS code(s) of the population on the processor.
