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??)

i have attached both config files for the compilations, the thornlist 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 have attached the logs of both an imac and cluster run)

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

best wishes,

Vassili
