Dear List,
i am getting a segfault with no apparent reason when trying to use
HIPS
through AztecOO
i attach the makefile.inc used in compiling hips
the configure i use for the trilinos
the file that i use to attempt using the solver...
my system is ubuntu 12.04 and i use OpenMPI
i use our own python wrappers to trilinos, the settings are given as
aztec_parameters = ParameterList()
aztec_parameters.set("AZ_solver", "AZ_gmres")
aztec_parameters.set("AZ_kspace", 100)
aztec_parameters.set("AZ_output", 1)
preconditioner_type = "HIPS"
preconditioner_parameters = ParameterList()
preconditioner_parameters.set("hips: id",0);
#preconditioner_parameters.set("hips: strategy",1) ---> note that i set
this in the C++ code!!
overlap_level = 0
nit_max = 300
tol = 1e-6
solver.structure_linear_solver = AztecSolver(aztec_parameters,
preconditioner_type, preconditioner_parameters, tol, nit_max, overlap_level)
#so
any hint on what i may be doing wrong will be very welcome (i am convinced
i miss a fundamental parameter but the failure provides no info at all...)
thanks in advance
Riccardo
