+Parallelized and vectorized SpMV on Intel Xeon Phi (Knights Landing). <br>
 This is the artifact of our CGO'2018 paper [ CVR: Efficient SpMV Vectorization on X86 Processors ].
 
 # Build
 CVR can be built simply with 'make', while the resulted binariy file is 'spmv.cvr'.

 # Data set Preparation and Execution
 Our implementation of CVR supports sparse matrices with matrix market format, which is one of the default formats in SuiteSparse Matrix Collection. Most of the data sets used in our paper can be found in either of these two collections:
 
-		1) [SuiteSparse Matrix Collection](https://sparse.tamu.edu) (formerly the University of Florida Sparse Matrix Collection).
-		2) [Stanford Large Network Dataset Collection](http://snap.stanford.edu/data/) (SNAP).

 Here, we use web-Google for example to show how to use CVR:
 
-		step 1: ./run_sample.sh
+	step 1: ./run_sample.sh
 
 The CVR accepts three parameters: file path; Number of Threads; Number of Iterations. <br>
 In run_sample.sh, there is a command like this:
 
-		numactl --membind=1 ./spmv.cvr [filepath] [numThreads] [numIterations]
+	numactl --membind=1 ./spmv.cvr [filepath] [numThreads] [numIterations]
 
-		numactl --membind=1 ./spmv.cvr dataset/web-Google.mtx 68 1000
+	numactl --membind=1 ./spmv.cvr dataset/web-Google.mtx 68 1000
 
 It means CVR reads a sparse matrix from "web-Google/web-Google.mtx" and execute SpMV with 272 threads for 1000 iterations.
