Somehow the recent versions of ACML seem not to like small 'lwork'.
ACML 1.5 works, while 2.0 and 2.5 crash with the "illegal value"
I have printed out some of the values from PW/cdiaghg.f90 :
nb = ILAENV( 1, 'ZHETRD', 'U', n, -1, -1, -1 )
IF ( nb < 1 ) nb = MAX( 1, n )
write(6,*) 'from ilaenv ',nb
IF ( nb == 1 .OR. nb >= n ) THEN
lwork = 2 * n - 1
write(6,*) 'branch1 ',n,lwork
lwork = ( nb + 1 ) * n
write(6,*) 'branch2 ',n,nb,lwork
When the crash happened, the following was printed:
Starting wfc are atomic
from ilaenv 28
branch1 9 17
lwork = 17
** ACML error: on entry to ZHEGVX parameter number 20 had an illegal
Is it really critical to minimize 'lwork'?
