PyRS: Cross-platform Data Fault-tolerant Storage Library Based on RS Erasure Code

<p>Erasure code has been used by more and researchers to solve the problem of efficient, reliable, fault-tolerant data storage. However, existing libraries based on erase can only run Linux platform, some them need GPU support. This paper implements a cross-platform storage library RS erasure code, PyRS, which is running CPU without support developed in Python. PyRS uses Vandermonde matrix as coding Numba NumPy speed up optimize program. compares with Jerasure same platform. The results show that encoding decoding 8 times faster than Jerasure. usage rate both about 25% memory 5% higher experiments are carried out Windows Experimental compared platform almost decoding, its increases 15%, while decreases 5%.</p> <p> </p>
