SZ3 error bounded by Euclidean norm? #318

Open mandelkow opened 2 months ago

mandelkow commented 2 months ago

Can the SZ3 compression algorithm be configured to use the Euclidean (L2) norm along one specific dimension as an error bound?

np.max( np.linalg.norm( Yh-Y, axis=-1)) <= ErrorBound

It doesn't seems so from the arguments we can pass to the hdf5 compression filter, but please ask your question to the SZ3 library authors: https://github.com/szcompressor/SZ3
