components

ipc_ status

reported return status:

• 0

  success

• -1

  allocation error

• -2

  deallocation error

• -3

  matrix data faulty (.n < 1, .ne < 0)

• -20

  alegedly +ve definite matrix is not

ipc_ alloc_status

Fortran STAT value after allocate failure.

ipc_ factorization_status

status return from factorization

ipc_ iter

number of iterations required

ipc_ cg_iter

number of CG iterations required

rpc_ obj

current value of the objective function

rpc_ norm_pg

current value of the projected gradient

char bad_alloc[81]

name of array which provoked an allocate failure

struct bqp_time_type time

times for various stages

struct sbls_inform_type sbls_inform

inform values from SBLS
