+Syntax to compile files:
+g++ filename.cpp -o filename 
+
+Optional flags:
+-DDEBUG : Enables the printing of debug information
+-DP1000 : Enables the use of 1000 byte packets
+-DP10000 : Enables the use of 10,000 byte packets
+
+Commandline arguments:
+Only client.cpp takes commandline arguments
+The first argument is bypass_offload : if 0 then the program runs with offload, else it bypasses offload.
+The second argument is proportion : determines what proportion of writes are inconsistent (if proportion = x, then the inconsistent to consistent write ratio is 1:x-1)
+
+Execution for offloaded mode (in order):
+1)Run offload.cpp on ub05's SmartNIC
+2)Run client.cpp on user (as ./client 0 n)
+3)Run master.cpp on ub05
+
+
+Execution for non-offloaded mode (in order):
+1)no_offload_master.cpp runs on ub05
+2)client.cpp runs on user (as ./client 1 n)
