# This generic script maps one or several multi-tasks applications on a specific 
# instance of the multi-processors/multi-clusters TSAR architecture. 
# It generates the files required for hardware and software compilation:
# 1) The "hard_config.h" file is used to generate the top.cppnetbsd file (hardware),
#    and to compile the tsar_preloader.elf, the GietVM boot.elf and kernel.elf files.
# 2) The optionals "map.bin" and vsegs.ld" files are used to configure the GietVM.
# 3) The optional "netbsd.dts" file can be used to configure NetBSD.
# 4) The optional "arch.bib" file can be used to configure ALMOS.
# 5) An optional "map.xml" file can be generated for debug. 
#######################################################################################
# The hardware parameters  are:
#  - x_size    : number of clusters in a row
#  - y_size    : number of clusters in a column
#  - nprocs    : number of processors per cluster
#######################################################################################
# The supported platforms are:
# - tsar_generic_iob
# - tsar_generic_leti
#######################################################################################
# The supported parallel applications are:
# - sort (one thread per processor)
# - transpose (one thread per processor)
# - convol (one thread per processor)
