Re: MPI compilation in cygwin/XP

MPI is not trivial, and for an average (i.e. not a sysadmin guru) NEURON user it looks even less so from within cygwin: The following post is an annotated log of my attempt to build a functional MPI set of services, which shows how quickly issues accumulate into 'rocket-science' proportions. Now thi...

Re: MPI compilation in cygwin/XP

cf. my last post https://svn.mcs.anl.gov/repos/mpi/mpich2/tags/release/MPICH2_1_0_7/README.vin is pretty comprehensive, but a shorter (hence less scary for a novice user ;-) and more cygwin/NEURON (bash) - specific version would be in order echo $SHELL /bin/bash In particular (cf. hines' post) to po...

Re: MPI compilation in cygwin/XP

One more Indeed, there is no provision for any MPI compilation in the MPICH2 .. .MSI Hence hines was right suggesting a complete rebuild of MPICH2 from source under cygwin Is it possible to add some notes to this effect in the MSWin set of install notes?

Re: MPI compilation in cygwin/XP

All this is very useful, but does not explain why the NRN configure does not find any of the 1.0.7 mpich2 within my cygwin installation.

I think it is just because none of mpich2 is on the $PATH.

Re: MPI compilation in cygwin/XP

Ok.
Now, would the NEURON/MPI not work just because I've installed
cygwin (+gcc etc & the NEURON subtree) on D: (no space on C:)
