Codes from Publications  Kurt Jacobs

This page contains codes from various publications of mine. If you want one that is not listed feel free to
request it.  The files are gzipped tarballs, that unpack into their own directory. All codes are C++,
or C++/MPI, all compiled using gcc, with Matlab scripts that display the results. Some codes also have
Python
scripts used to submit multiple jobs to a queueing system, and some require that you install FFTW
I'm affraid I cannot assist if you have problems compiling or running the codes. But if "make" doesn't work
the first time, run it a second time. You need to have mkdep installed. If you find an error in any code that
means that it does not properly solve the intended problem, please let me know. These codes are not licensed
in any way — you may do with them what you wish. Of course, they also have no warrantee whatsoever —
not even the implied warrantee of fitness for an intended purpose. You use them at your own risk.
