Description
The program
gcv
is the source graph converter. It takes on input a graph
file of the format specified with the
-i
option, and outputs its equivalent
in the format specified with the
-o
option, along with its associated geom-
etry file whenever geometry data is available. At the time being, it accepts
four input formats: the Matrix Market format [5], the Harwell-Boeing col-
lection format [10], the
Chaco
/
MeTiS
graph format [24], and the
Scotch
format. Three output format are available: the Matrix Market format, the
Chaco
/
MeTiS
graph format and the
Scotch
source graph and geometry
data format.
