#1480: Catastrophic test failures with Intel 11 -----------------------------------+---------------------------------------- Reporter: hinder | Owner: Type: defect | Status: new Priority: blocker | Milestone: ET_2013_11 Component: EinsteinToolkit thorn | Version: development version Keywords: | -----------------------------------+---------------------------------------- Several tests fail with very large differences or NaNs with Intel 11, but not with later versions of the compiler. We suspect this is due to a buggy implementation of Cray pointers, newly used in GRHydro since the last release. The affected tests are:
{{{ GRHydro_test_shock_mp5 (from GRHydro) GRHydro_test_shock_ppm (from GRHydro) GRHydro_test_shock_weno (from GRHydro) tov_slowsector (from GRHydro) diag_flip_pugh_eno (from Hydro_InitExcision) diag_pugh_eno (from Hydro_InitExcision) halfsphere_pugh_ppm (from Hydro_InitExcision) sphere_pugh_ppm (from Hydro_InitExcision) x_flip_pugh_eno (from Hydro_InitExcision) x_pugh_eno (from Hydro_InitExcision) }}}
Roland is going to try to implement a workaround for the compiler bug.
