HPL_pdinfo reads the startup information for the various tests and
transmits it to all processes.
- TEST (global output) HPL_T_test *
- On entry, TEST points to a testing data structure. On exit, the fields of
this data structure are initialized as follows: TEST->outfp specifies
the output file where the results will be printed. It is only defined and
used by the process 0 of the grid. TEST->thrsh specifies the threshhold
value for the test ratio. TEST->epsil is the relative machine precision
of the distributed computer. Finally the test counters, kfail, kpass,
kskip, ktest are initialized to zero.
- NS (global output) int *
- On exit, NS specifies the number of different problem sizes to be tested.
NS is less than or equal to HPL_MAX_PARAM.
- N (global output) int *
- On entry, N is an array of dimension HPL_MAX_PARAM. On exit, the first NS
entries of this array contain the problem sizes to run the code with.
- NBS (global output) int *
- On exit, NBS specifies the number of different distribution blocking
factors to be tested. NBS must be less than or equal to
HPL_MAX_PARAM.
- NB (global output) int *
- On exit, PMAPPIN specifies the process mapping onto the no- des of the MPI
machine configuration. PMAPPIN defaults to row-major ordering.
- PMAPPIN (global output) HPL_T_ORDER *
- On entry, NB is an array of dimension HPL_MAX_PARAM. On exit, the first
NBS entries of this array contain the values of the various distribution
blocking factors, to run the code with.
- NPQS (global output) int *
- On exit, NPQS specifies the number of different values that can be used
for P and Q, i.e., the number of process grids to run the code with. NPQS
must be less than or equal to HPL_MAX_PARAM.
- P (global output) int *
- On entry, P is an array of dimension HPL_MAX_PARAM. On exit, the first
NPQS entries of this array contain the values of P, the number of process
rows of the NPQS grids to run the code with.
- Q (global output) int *
- On entry, Q is an array of dimension HPL_MAX_PARAM. On exit, the first
NPQS entries of this array contain the values of Q, the number of process
columns of the NPQS grids to run the code with.
- NPFS (global output) int *
- On exit, NPFS specifies the number of different values that can be used
for PF : the panel factorization algorithm to run the code with. NPFS is
less than or equal to HPL_MAX_PARAM.
- PF (global output) HPL_T_FACT *
- On entry, PF is an array of dimension HPL_MAX_PARAM. On exit, the first
NPFS entries of this array contain the various panel factorization
algorithms to run the code with.
- NBMS (global output) int *
- On exit, NBMS specifies the number of various recursive stopping criteria
to be tested. NBMS must be less than or equal to HPL_MAX_PARAM.
- NBM (global output) int *
- On entry, NBM is an array of dimension HPL_MAX_PARAM. On exit, the first
NBMS entries of this array contain the values of the various recursive
stopping criteria to be tested.
- NDVS (global output) int *
- On exit, NDVS specifies the number of various numbers of panels in
recursion to be tested. NDVS is less than or equal to HPL_MAX_PARAM.
- NDV (global output) int *
- On entry, NDV is an array of dimension HPL_MAX_PARAM. On exit, the first
NDVS entries of this array contain the values of the various numbers of
panels in recursion to be tested.
- NRFS (global output) int *
- On exit, NRFS specifies the number of different values that can be used
for RF : the recursive factorization algorithm to be tested. NRFS is less
than or equal to HPL_MAX_PARAM.
- RF (global output) HPL_T_FACT *
- On entry, RF is an array of dimension HPL_MAX_PARAM. On exit, the first
NRFS entries of this array contain the various recursive factorization
algorithms to run the code with.
- NTPS (global output) int *
- On exit, NTPS specifies the number of different values that can be used
for the broadcast topologies to be tested. NTPS is less than or equal to
HPL_MAX_PARAM.
- TP (global output) HPL_T_TOP *
- On entry, TP is an array of dimension HPL_MAX_PARAM. On exit, the first
NTPS entries of this array contain the various broadcast (along rows)
topologies to run the code with.
- NDHS (global output) int *
- On exit, NDHS specifies the number of different values that can be used
for the lookahead depths to be tested. NDHS is less than or equal to
HPL_MAX_PARAM.
- DH (global output) int *
- On entry, DH is an array of dimension HPL_MAX_PARAM. On exit, the first
NDHS entries of this array contain the values of lookahead depths to run
the code with. Such a value is at least 0 (no-lookahead) or greater than
zero.
- FSWAP (global output) HPL_T_SWAP *
- On exit, FSWAP specifies the swapping algorithm to be used in all
tests.
- TSWAP (global output) int *
- On exit, TSWAP specifies the swapping threshold as a number of columns
when the mixed swapping algorithm was chosen.
- L1NOTRA (global output) int *
- On exit, L1NOTRAN specifies whether the upper triangle of the panels of
columns should be stored in no-transposed form (L1NOTRAN=1) or in
transposed form (L1NOTRAN=0).
- UNOTRAN (global output) int *
- On exit, UNOTRAN specifies whether the panels of rows should be stored in
no-transposed form (UNOTRAN=1) or transposed form (UNOTRAN=0) during their
