The GRASS GIS module r.series ( man page ) can do this. You can pass
the list of input rasters as a comma separated list on the command
line, or as a file, with one raster name per line. So (assuming a
linux bash shell) if the rasters are named as in your example:

RAST_LIST=`g.list rast pattern="raster*" separator=comma`
g.region rast=$RAST_LIST
r.series input=$RAST_LIST output=raster_sum method=sum
