#  Name: emulation.py
#  Description: emulation script for runing program on DAS2 or linux
#               to create number of instance in one node 
#  Usage:1) For create instance over different nodes(cpu)
#        using the following command:
#
#        a) in the das2:
#        prun emulation.py num_of_nodes num_of_instance other_prg_param 
#
#        b) in the normal linux:
#        python emulation.py nodeid num_of_nodes num_of_instance other_prg_param 
#        example settings:
#        python emulation.py 0         1         num_of_instance other_prg_param
#
#        by doing this, {nodeid, num_of_nodes,  num_of_instance, other_prg_param}
#        becomes input parameters for emulation.py
#       
#       2) other_prg_param including:
#        ExperimentType  RandomCacheSize  BuddyCacheSize r(i.e.Exploration/explitation Rate) ... 
#
#      
#       3)Output: create many instance over nodes
#       For each instance:
#       prgname  nodeid num_of_nodes instanceid num_of_instance other_prg_param
#
#       4) Example:
#         python emulation.py 0 1 1 1 20 20 0.5
