Dear forum members,
Do anybody have experience with very large models ?
I have a automatically generated model containing 370.000 wires.
Running this model on Windows causes memory exception due to 2GB limitation of a 32bit machine. Does the limitation also exist on a 64bit Linux system ?
Thanks in advance |

Dear forum members,
I found a solution. I've installed Fedora Core 7.9 on a Pentium 4 machine, so it automatically installs a 64bit linux system.
It is downloadable from fedoraproject.org
I took the source code of FastHenry from MIT
ht p://w w.rle.mit.edu/cpg/codes/fasthenry-3.0-12Nov96.tar.z
and did some changes so it compiles [:D]. You can save the following text to your disk and use "patch" to update the sources if you have the same demand.
I've tested it and 2GB doesn't seem to be a issue anymore. It still works fine due I've checked it by running th 30pin.inp on windows as well on my patched version. The result is the same as expected [8D].
If you have a AMD x64, you will have to change the Makefiles. [;)]
Have fun using it !
