What is CAMP-Atami

Our program CAMP-Atami is developed by active members of the physics working group in CAMM Forum , who are mainly working in Japanese industries. One purpose of this collaborated research is to make a standard code when we start to study and understand an ab-initio molecular dynamics based on the Car-Parrinello method. To perform this project, every participated researcher worked on this development using his off-duty time. All modules of the program were developed by the members listed below. They were put together at the meeting , which was held once a month, and we studied and debugged this program there. In this challenging collaboration, our CAMP-Atami was developed and completed. Since this active group of the physics working group consists of the researchers who are working in various fields of computational materials physics, we needed to make our communication effective, and to make our problems clear while we are developing this program. In order to realize this, we wrote an instruction manual, including application results, which was organized using a member's small memorandum, or a small comment from our notes. In the process of the final debuggings using some applications, we realized that further improvement and introduction of new calculation methods were required for our CAMP-Atami. Also, to keep our study of the Car-Parrinello type program and activity of this working group, we decided to make our program CAMP-Atami open publicly through JCPE with our instruction manual. At the same time, we hope that this submission of our program to JCPE will help our activity to be encouraged by a lot of information from users, and we also expect many researchers are interested in computational materials physics, and will work in this field.

What we are asking for the users of this program is quite simple: to send the various kinds of information which you find using this program; to keep the rule when the source code is changed; to make an acknowledge to us (the program must be cited as CAMP-Atami ). Only these three issues are required to the users. The attention and detail of the guideline are referred in the appendix 2 "Using CAMP-Atami" in the last page[11] of the instruction manual. The figure there is shown below for short.

Notes

  1. It stands for Computer Aided Materials and Molecular Design. Refer to CAMM NEWS as to the process of developing this program and the history of the name "CAMP-Atami", which is included in the instruction manual.

  2. The active members of the physics working group of CAMM Forum. This meeting about the Car-Parrinello method was organized by H.Rikukawa (Fuji Electrochemical) et. al., and this activity is still alive. A new member is quite welcome at our working group.

  3. This project was proposed and planed by S. Ohnishi(NEC), A. Fukumoto(Toyota Central Research Lab.) and T. Matsumiya (Nippon Steel) et. al. Each module of this program was developed by some groups, which are organized according to the location of the member's office.

(*) stands for the group leader.  The group leader in G4 was
Y.Zempo(Sumitomo Chemical) in the first stage, and the role was
transferred to T.Saito(Sony) in the final stage.
  4. The arrangement of whole program was done by Y.Zempo(Sumitomo Chemical), and the role was transferred to T.Saito(Sony) later.

  5. The final development of this program was done by T.Saito(Sony).

  6. The planning and arrangement of the instruction manual was done by Y.Ohtani (Fuji Research Inst).

  7. Any suggestions and comments about this program "CAMP-Atami" are always welcome. For example, we would appreciate it if the user would send us the successful/failure experiences of calculations and the information of machine dependency and computer circumstances, etc.

  8. We mainly use E-mail in this communication. Of course, it is our pleasure to have a discussion about user's results in the working group meeting. Please refer to the Appendix 2 "Using CAMP-Atami" of the instruction manual. Our E-mail address is tentatively contact@camp.or.jp, and it may be changed in the near future.

  9. Please send the code. According to the policy of CAMP-Atami above, it will be added to the next version of CAMP-Atami, if it is adopted. This kind of contribution will be referred in the comment of each corresponding subroutine.

  10. It must be cited as CAMP-Atami.
