I used to work (current PhD student) in HPC (switched specialties) and I was extremely surprised that not only did these people not share code (DOE actually encourages open souring code), but they would not even do so upon request. Several times I had to get my advisor to ask the author's advisor. Several times I found out why I couldn't replicate another person's code. It is amazing to me that anyone in CS does not share code. It is trivial to do and we're all using git in some form or another anyways.
