import of atlc-2.32 ------ Atlc is a finite difference programme that is used to calculate the properties of a two-conductor electrical transmission line of arbitrary cross section. It is used whenever there are no analytical formula known, yet you still require an answer. It can calculate: The impedance Zo (in Ohms) The capacitance per unit length (pF/m) The inductance per unit length (nF/m) The velocity of propogation v (m/s) The velocity factor, v/c, which is dimensionless. A bitmap file (usually with the extension .bmp or .BMP) of the cross section of the transmission line is drawn in a graphics package such as The Gimp and then analyzed using Atlc. 2002-03-13 13:42:59 +01:00
update to atlc-4.6.0 Many many improvements and bug fixes since the last packaged release. A partial list is: atlc should no longer fail any test on a multi-processor system configured with --with-threads. The algorithm used for both single processor and multiple processor (i.e. threaded code is the same). The -t option to atlc, which sets the number of threads when configured for multiple processors can be set to 0 to use entirely the single-threaded algorithm. If set to one, it will use the multi-threaded algoritm, but use only one thread. If set to some other number, it will use that number of threads and be optimal for the same number of cpus. Added some support for gathering hardware data under Linux. Removed MPI support, as its not working at all. Changes made to the code to remove the need for a type long long, which should make the code more portable. Some changes have been made to the bests so that when the benchmark runs it should not produce junk for the hardware information on any system. Previosly is could create a lot of junk, that was all wrong. uname is now only called once from try_portable.c and the splatform specific stuff computed elsewhere atlc now runs on anything from a toy to a supercomuter! Yes, that is right. An early version of atlc has been run on a Sony Playstation 2 games console and version 4.4.0 has been tested on the Cray Y-MP supercomputer!! It has also been run on a very large number of other UNIX systems, so is hopefully very portable. An option that was previously reccommended --enable-hardware-info has been removed. It is now enabled by default, but can be over-ridden with --disable-hardware-info. Added a system call to get the number of configured processors online in Linux. This seems to be undocumented so it not without its risks, but it seems to work okay on the limited number of systems tested on. Someone has done a Windoze port of atlc. Appently it took just 5 minutes, from start to finish. A single bug was found that prevented atlc compiling, but that was fixed - it needed a left brace removed. This had never been seen on a UNIX system, since the offending code was between a couple of #define's. It has been bought to my attention that bitmaps created with Photoshop prior to version 7.01 could not be read by atlc. This was not a fault of Photoshop, but of atlc, so that bug has been fixed. NEWS for realease 4.6.0 Nobember 2003. This is a very different from the last release (4.5.1) in two very important ways. 1) The basic accuracy for single dielectrics has been improved. Now typical errors are only around 0.1% 2) I have re-enabled the calculation of multiple dielectrics which were disabled due to accuracy concerns. I'm still not 100% happy with the algorithms, but on tests with a dual coaxial cable with two dielectrics shows errors of under 2%, I hope to improve this further at a later date. 2004-11-27 21:49:24 +01:00			`SHA1 (atlc-4.6.0.tar.gz) = 4c2185e17812925351345465094e2036fefa9724`
