Hello all ，could someone tell me what is the function of the following code
（it is in the Ruby.py file），or where could I find the explanation ？Thank
very much！ ：
def create_system(options, system, piobus = None, dma_devices = []):
protocol = buildEnv['PROTOCOL']
exec "import %s" % protocol
try:
(cpu_sequencers, dir_cntrls, all_cntrls) =
eval("%s.create_system(options, system, piobus, dma_devices)" % protocol)
except:
print "Error: could not create sytem for ruby protocol %s" %
protocol
raise
#
# Important: the topology must be created before the network and after
the
# controllers.
#
exec "import %s" % options.topology
try:
net_topology = eval("%s.makeTopology(all_cntrls, options)"%
options.topology)
except:
print "Error: could not create topology %s" % options.topology
raise
if options.garnet_network == "fixed":
network = GarnetNetwork_d(topology = net_topology)
elif options.garnet_network == "flexible":
network = GarnetNetwork(topology = net_topology)
else:
network = SimpleNetwork(topology = net_topology)
