[Users] different results of runs on different machines

[Vassilios Mewes]

Hello all,

i have a working installation of the einstein toolkit (compilation finished
with all done.) on both my imac at work and on a local cluster at the
university of valencia...both are installation of the 2012_05 release...

i have written thorns to read in and extrapolate RNSID-like initial data to
the cartesian grid of the einstein toolkit..

the code runs on my imac, but gives NaNs and therefore segmentation faults
on the cluster..

the imac version was compiled with g++-4.7 and gfortran-4.7 and the version
on the cluster with ifort 12.0 (although i think that this shouldn't be an
issue??)

the thornlist used to compile the two configurations is the one coming with
a fresh checkout, and i have just added my two thorns to it....

running on the imac, the data is read in and interpolated without errors or
nans popping up...

on the cluster, there seems to be a problem with the initial data, and the
code crashes on segmentation faults

i don't know whats causing this, could the problem be caused by the
different compilers on the two machines?


best wishes,

Vassili
