Can you provide any preliminary data on Julia vs C++ runtime for iTensor’s DMRG? Is the algorithm implemented in Julia the same 2-site algorithm implemented in Julia?

Yes, it is the same algorithm between the two version. We hope to do some systematic benchmarking soon, but in general we have seen the Julia version is anywhere from 5% slower to 100% slower, depending on the problem and bond dimension.

Formatting Tips:
  • To format code, indent by four spaces
  • To format inline LaTeX, surround it by @@ on both sides
  • To format LaTeX on its own line, surround it by $$ above and below
  • For LaTeX, it may be necessary to backslash-escape underscore characters to obtain proper formatting. So for example writing \sum\_i to represent a sum over i.
