# Description : 
# - This script will generate TSAR hardware description, 
#   compile it to BIB binary format and than it will start 
#   TSAR simulator.
#
# - The following arguments can be passed to this script (order is not relevant)
#     -xmax: number of clusters in a row
#     -ymax: number of clusters in a column
#     -nproc: number of CPUs per Cluster
#     -xfb: frameBuffer's X-length
#     -yfb: frameBuffer's Y-length
#     -bscpu: BootStrap CPU (0 to xmax*ymax*nproc-1)
#     -memsz: per cluster memory size in bytes.
#     -o: output file name
#     -g: generate TSAR hardware description, dont call the simulator.
#   Default values are (in order) 2 2 4 XX 0x800000 "arch-info.bin"
