I have a desktop dual-core dual CPUs for a total of 4 core running Win XP. At the moment I run Neuron 5.8.88 using only one of the core.
Is it possible to run all 4 cores to speed up optimization? If so how can I do that in WinXP?
Thanks

Parallel Run fitter on Win Xp
I don't have a decent HOW-TO yet for setting up NEURON on mswin to run in parallel. However it is supported and lets see if I can explain enough of it here so you can get it going. By installing the
mpich version of mpi, you will be able to
run parallel networks with gap junctions as well as embarassingly parallel programs using the ParallelContext.
This is not for the faint of heart.
1) get to the point where you have at least once built NEURON under mswin from the sources by following the instructions at
http://www.neuron.yale.edu/neuron/insta ... mswin.html
Note that this involves installing the cygwin development environment, downloading the latest alpha versions of the tar.gz files from http://www.neuron.yale.edu/ftp/neuron/versions/alpha/
(both iv-17.tar.gz and nrn-5.8...tar.gz)
2) look at neuron/nrn/mswinmpiconf and do what it says. Especially note the comments at the top of that file.
If there is any demand, then perhaps I can supply an appropriate setup.exe
someday.
