Yes, I am aware of this issue. (See also https://github.com/Cytnx-dev/Cytnx/issues/473#issuecomment-2351646127) I don't think there is a 'canonical' version of FindLAPACKE. One simple way (as I see in some of the...

Somehow I never compile successfully if I only install reference BLAS/LAPACK.....

What is the reason that it will be easier to use than LAPACKE?

For Fig.12 (of SciPost paper) ````python import cytnx import numpy as np net = cytnx.Network() net.FromString(["c0: t0-c0, t3-c0",\ "c1: t1-c1, t0-c1",\ "c2: t2-c2, t1-c2",\ "c3: t3-c3, t2-c3",\ "t0: t0-c1, w-t0,...

I find something strange. If I modify the bond dimension of c0's t3-c0 bond, but DO NOT modify the bond dimension of t0's t3-c0 bond, I still can get a...

I agree the general direction of the suggestion. Can someone comments on the performance? For example, if we drop CUTT, do we lose any performance?
