In this version of thinDedup, we prototype thinDedup in the user space, not as a device mapper target. 
It is noted that, the code still uses the dmdedup framework and follows its read/write interfaces.

 In this version of code, we support two kinds of workloads: microbenchmark and fiu traces.



Steps to use the code:

1. compile
	

For microbenchmark test: make micro/micro_opt
	
For FIU trace test: make debug/opt

2. run the test
	
For microbenchmark test, run like below
	

zDedup_micro.opt -f nullfile -df $data_dev -mf $meta_dev  -N $n -ps $ps -t $th -dr $dr -nc 

	

NOTE: two files must be created in advance (data_dev, meta_dev)

	For FIU traces test, run like below
	

zDedup.opt -f fiu_trace -dc  -t window_size $n num_requests

	

NOTE: the fiu trace a pre-processed to binary format, refer to load_trace for more details
