program test_real2 ( )

Fortran test programm to demonstrates the use of ELPA 2 real case library. If "HAVE_REDIRECT" was defined at build time the stdout and stderr output of each MPI task can be redirected to files if the environment variable "REDIRECT_ELPA_TEST_OUTPUT" is set to "true".

By calling executable [arg1] [arg2] [arg3] [arg4] one can define the size (arg1), the number of Eigenvectors to compute (arg2), and the blocking (arg3). If these values are not set default values (4000, 1500, 16) are choosen. If these values are set the 4th argument can be "output", which specifies that the EV's are written to an ascii file.

The real ELPA 2 kernel is set as the default kernel. However, this can be overriden by setting the environment variable "REAL_ELPA_KERNEL" to an appropiate value.
