DMRG++ is free software. See the file LICENSE, also in the code repository.
The easiest way to obtain DMRG++ is to use git to clone my github.com repository. You clone only once. After that, you can update the code to its latest revision by running git pull at any time.
$ cd someDirectory/ $ git clone https://github.com/g1257/PsimagLite.git $ git clone https://github.com/g1257/dmrgpp.git
To later update the code(s) just say:
$ cd someDirectory/ $ cd dmrgpp/ $ git pull $ cd ../PsimagLite/ $ git pull
You can run git rev-parse HEAD to
get the SHA1 hash for the revision you are using. Downloading the
code from github.com over
secure http (https) is possible, make sure to specify https when cloning, as indicated above. Hash of
the latest commit is also posted at
Latest commit should always be signed. Keys at https://g1257.github.io/keys.html.
As an alternative, you can go to github.com and click on the download button. This has the disadvantage that you will not be able to use git pull to update the code later.
