Will defer to Thomas, as it is a purely OpenACC change. One way to do it is /* { dg-additional-options "-DEXPENSIVE" { target run_expensive_tests } } */ and using #ifdef EXPENSIVE #define N 100 #else #define N 50 #endif etc., that way the tests will be normally scaled down, but with GCC_TEST_RUN_EXPENSIVE=1 in the environment one can still request the more expensive tests. For the Fortran test it would mean .F90 extension though... Jakub
