LAPACK freezing during the test

Hi Dominique:

Thank you very much for the information, I will try varying the optimization flags and also the compiler and I will post here what happens.

be happy,

Andres,
you might as well switch to lapack-3.1, as mentionned by Dominique, his patch
is ok but refers to 3.0, slarre as been changed a lot from 3.0 to 3.1 thanks to
work from Beresford Parlett, Jim Demmel, Inderjit Dhillon, Osni Marques, and Christof
Voemel and there is no need for this patch any more.
(Thanks Dominique anyhow for the pacth on 3.0.)
Julien.

Hi Julien:

I'm using LAPACK 3.1.0, and my problem is with xlintsts which is the first test LAPACK does, last time my problem was with the eigenvalue test, I haven't checked the other tests in this architecture yet.

As Dominique suggested I changed the compilation options to no optimization i.e. f77 -f -u and it stalls in a different place:

TRANS='N', M= 5, N= 10, NRHS= 15, NB= 1, type 2, test( 2)= 0.16801E+07
TRANS='T', M= 5, N= 10, NRHS= 15, NB= 1, type 2, test( 2)= 0.10074E+07
TRANS='N', M= 5, N= 10, NRHS= 15, NB= 3, type 2, test( 2)= 0.18362E+07
TRANS='T', M= 5, N= 10, NRHS= 15, NB= 3, type 2, test( 2)= 0.11995E+07
TRANS='N', M= 5, N= 10, NRHS= 15, NB= 3, type 2, test( 2)= 0.16361E+07
TRANS='T', M= 5, N= 10, NRHS= 15, NB= 3, type 2, test( 2)= 0.97411E+06
TRANS='N', M= 5, N= 10, NRHS= 15, NB= 3, type 2, test( 2)= 0.18796E+07
TRANS='T', M= 5, N= 10, NRHS= 15, NB= 3, type 2, test( 2)= 0.11708E+07
TRANS='N', M= 5, N= 10, NRHS= 15, NB= 20, type 2, test( 2)= 0.18971E+07
TRANS='T', M= 5, N= 10, NRHS= 15, NB= 20, type 2, test( 2)= 0.82252E+06

I'm going to try with g77.

If you have any ideas I will certainly give them a try.

thank you very much,

Andrés

hello Andres, can you start a new post topics and reminding lapack-version/machine/compiler/blas/flags and restate the problem, please? I have half of the answer to teh questions above by digging in the previous post but I am lost in this topic, too many post, non related. That would be good to start fresh, Cheers, Julien.
