Hello all,
I can have a look at the bluewaters failures (one of them is a hydro failure so they default to me anyhow).
The hydro failure (balsara4_2d) goes away when I compile with -O3 instead of -Ofast so it seems that this is another case where hydro is very susceptible to roundoff level errors being amplified. Please note that balsara4_1d (the 1d version of this test) already has larger error threshold so I think I will raise the 2d thresholds to the same value. This test has very high Lorentz factors in the data so can very hard for the code. With this I still get test failures for Schwarzschild_EF, regression_test (in SphericalHarmonicRecon) and twopunctures_carpet.
Yours, Roland
