Aaron: This new version of tiegcm is called tgcm14a. It runs on Crays and SGI O2K. The mpi stuff is NOT ready -- it is being developed for the IBM SP's -- but will be ignored by the Makefile when running under IRIX. I have put 2 tar files on anon ftp at ftp.hao.ucar.edu in /pub/foster: -rw-r--r-- 1 foster ftp 73809920 Mar 3 09:23 tgcm14a_data.tar -rw-r--r-- 1 foster ftp 1239040 Mar 3 09:28 tgcm14a_src.tar The data file contains a netcdf primary history file, which you can use as a SOURCE file for input. It has 5 histories on it (1,0,0 to 5,0,0). The data tar file also has 2 netcdf files for gpi and magnetic field data. All netcdf files have a ".nc" suffix. The source tar file was made as follows: tar cf tgcm14a_src.tar Makefile Depends Objects mkdep \ tgcm.setup tgcm.exec *.h *.f *.F *.inp *.ncd The Makefile is a gnu file (I use gnumake on our o2k). The Makefile includes the files Depends and Objects, which list depedencies for the make. These 2 files can be generated with the perl script mkdep, also in the source tar file. Any time you change the code in a way that will affect dependencies, just run "perl mkdep" to refigure the dependencies before remaking -- it handles both include and use statements. I included the tgcm.setup and tgcm.exec scripts only for your information -- these scripts are used when we submit production runs -- you shouldnt need to execute them, but check them out, esp the env vars that are set for IRIX in tgcm.exec. There is a sample input file (tgcm14a.inp I think), and the *.ncd file is an ncdump of the history file, as folllows: ncdump -v"lon,lat,lev,mtime,year,day,ut,timestep,f107d,f107a, \ hpower,ctpoten,byimf,mag,dtide,sdtide,colfac,p0,nflds" As before, I have not tested this on non-ncar machines -- obviously you may have different compilers, etc, and I may have forgotten to include something. Let me know how it goes... --Ben Let me know when you get the tar files, so I can remove the big one from the hao disk.
