hi!!!
here is some part of script for number of threads per cpu
--------------------------------------------------------------------------------------------------
# Set num_thrds_per_cpu
num_thrds_per_cpu = 1
system = System(cpu = [CPUClass(cpu_id = i) for i in xrange(np)],
physmem = PhysicalMemory(range = AddrRange("2GB")),
membus = ToMemBus(), mem_mode = test_mem_mode)
system.physmem.port = system.membus.port
------------------------------------------------------------------------------------------------
# Assign Benchmarks from pre-created benchmark file
filename = "/home/hariv/m5-2.0b6/configs/cpu2006/" +"benchmarks_" + str(np)
+ "core_" + str(num_thrds_per_cpu) + "threadpercore.dat"
FILE = open(filename, "r")
Data = FILE.readline()
#print Data
FILE.close()
Data1 = Data.rsplit('/')
#print Data1
count = Data1.index('\n')
NumBenchmarks = Data1[0]
BenchmarkList = [0] * int(count-1)
for i in range(int(count - 1)):
BenchmarkList[i] = "Mybench." + Data1[i + 1]
#print Data1[i + 1]
#print BenchmarkList[i]
print 'num of cpus = %d' %np
print 'num threads per cpu = %d' %num_thrds_per_cpu
k = 0
for i in xrange(np):
expression = "system.cpu[" + str(i) + "].workload = ["
for j in xrange(num_thrds_per_cpu):
expression += BenchmarkList[k]
k = k + 1
if j != (num_thrds_per_cpu - 1):
expression += ", "
expression += "]"
print expression
exec(expression)
root = Root(system = system)
Simulation.run(options, root, system, FutureClass)
----------------------------------------------------------------------------------------------------------------------------
*Do i need to hack configs/example/se.py or use the use the patch by
Jiayuan Meng ?*
Thanks
