Release of SZ 2.1
In this version, we significantly improved the compression/decompression speed for point-wise relative error bound, with slightly degraded (1-5%) or the same compression ratios. The details can be found in our paper published in MSST19.
We also updated user guide correspondingly. The users can compare the old version (IEEE CLUSTER18) and new version (MSST19) by using the parameter 'accelerate_pw_rel_compression' in sz.config to switch between the two versions.
Other error bound modes (such as absolute error bound) are exactly the same as SZ 2.0.
