Some months ago jkshin@radon.sait.samsung.co.kr asked the net: > I am now trying to do first-principles Molecular Dynamics > Simulations(R. Car, M. Parrinello, Phys. Rev.

We, Computational Physics Working Group of "Computer Aided Materials and Molecular Design" Forum, have donated a Car-Parrinello MD program "CAMP Atami" to JCPE, hoping this may be useful for the people in computational physics/chemistry world. "CAMP Atami" is now available from JCPE. Please contact to JCPE (not to me!) to purchase the program. Programing Language is FORTRAN77. It is working on various UNIX machines, SUN, IRIS, NEWS, IBM, TITAN, HP, ALLIANT, CRAY, SX etc. Program No.: P089 Program Name: CAMP Atami (ver.1.0) Medium : 3.5" 2DD DOS format. (tar + compress + uuencoded) Fee : 2,500 yen. ($1 \approx 100 yen) Including (Japanese, sorry) Manual.

Could you tell us a ... uuhm, this has very severe linguistic problem ... Before talking about the manual, please note that developing the CAMP Atami code had been done on volunteer bases, even if it is sold from JCPE. Fee of the program is only a shipping cost.

However it will take, I suppose, half a year or so to translate the whole manual. It becomes too large to handle at a time. These may help You: A. A file containing compiling instructions are attached to the file set in English. B. A sample input file is also attached. C. Descriptions of the output files may not be provided in English. I will be able to tell you about them in that cases. D. Mailing list which devoted only on CAMP Atami will start soon. This mailing list will be set on some BBS in Japan, but you can sent and read mails via Inter-net Mail system without registration to the BBS. You may contact to the developers through the list. Address of the list is written on the manual. Any comments and questions on manual as well as on CAMP are appreciated. Please feel free to resent this message to others. | K.

[2] JCPE ("Japanese Chemical Program Exchange") is a Japanese Organization like QCPE. I announced the release of a Car-Parrinello MD program "CAMP Atami" to the net on April 5th. From that time I had received many emails which are questioning what CAMP dose or what is the cost for it in US dollar. Here I will describe them: 1. What is CAMP or Car-Parrinello MD. CAMP Atami is a program for an ab initio molecular dynamics, employing the algorithm suggested by R. Car and M. Parrinello[1,2]. CAMP is a rather straightforward implementation of their algorithm. Their algorithm is based on norm conserving pseudo potential band calculations. Pseudo-potential parameters of Bachelet-Hamann-Schl\"uter[3] are used in this program. Basis functions are plane waves only and a cyclic boundary conditions are imposed. The program first relaxes electrons to SCF state. Then, it begins MD steps according to calculated Faynmann forces. In MD steps, geometries of atoms and electronic structures are relaxed at the same time. So, you can perform ab initio MD calculations within pseudo potential frame work. Atoms are moved actually on a CP potential surface, however you can be close to BO potential surface by selecting time slices and a fictitious mass of electron. The Car-Parrinello algorithm is very lighter than MO based ab initio MD methods by tens of magnitude. However it still needs huge computer resources, CPU speed and memories. I think it is impossible to perform *meaningful* MD calculations on currently available computers, even if they are massively parallel computers. But it can be used for simulated annealing calculations to get to unknown grand state geometries of your target at certain conditions. These values are obtained from the program at each time step. 1. electronic eigen values. 2. total energy and its sources. (kinetic energy, hartree, exchange-correlation ...) 3. geometry(coordinates of each atom). 4. velocity. ... etc. [1] R. Car and M. Parrinello, Phys Rev. Lett. 55, 2417 (1985). [2] R. Car and M. Parrinello, NATO ASI SerB 186, 455 (1989). [3] G. B. Bachelet, D. R. Hamann and M. Schl\"uter, Phys. Rev. B 26, 4199 (1982). 2. Who made CAMP. CAMP was made by voluntary works of the members of Computational Physics Working group of CAMM (Computer Aided Material and Molecular design) Forum. CAMM Forum is consist of scientists and researchers from different companies. Please note that CAMM Forum, JCPE(distributer, see below) and my company are different and have no relations among them. 3. How to obtain CAMP. CAMP was first developed for our (members of CAMM Forum) internal use. However we decided to open the code for anyone who is interested in it. We selected JCPE as a distributer of the CAMP and *donated* the code to it. JCPE is a Japanese Institute for program exchange like QCPE. They are working at voluntary bases also. Please contact to JCPE to obtain CAMP. (Please do not send order to me.) Program No.: P089 Program Name: CAMP Atami (ver.1.0) Medium : 3.5" 2DD MS-DOS format. (tar + compress + uuencoded) Fee : 2,500 yen. Including (Japanese) Manual. (about $25, 100 yen is approximately $1.)

As far as I know, there is no extra charge for shipping outside Japan. They will not receive credit card. They prefer to receive the fee in yen (not US dollar). You need not to send a diskette to JCPE. A facsimile may be a most convenient way to contact with them. They do not have connection to the net. I do not have any means to ascertain your order if the response of JCPE is too late. 4. What we wish. We opened the code of CAMP hoping it may convenient for the people in computational physics/chemistry world. We would like to improve the code more efficient and more powerful. Some works for next version are already under way. So, we would like to ask you to share your experience on CAMP with us. We open a mailing list on CAMP. Please join our mailing list when you obtain CAMP. Address is written on the Manual. I hope this may help. best regards, | K.
