UPDATE: Re: Bug in lam-6.2pl3/blacs1.1/scalapack1.6 combo
UPDATE:
Greetings! I've managed to separate the bugs found into two classes,
and have fixed one via a lam configuration option.
1) Crashing on scalapack tests of certain size/block combos: This was
fixed by including the --without-shortcircuit configuration
option. So the short-circuit feature definitely still has
problems.
2) mpirun -O problems: Even though this is a homogenous cluster,
mpirun -O fails single precision BLACS and SCALAPACK tests. For
example, running the BLACS tester out of the box shows a failure on
the Integer BSBR test, among others. I haven't found the source of
this error yet, but its a question of numerical correctness, not of
program crashing at this point.
Updated Debian packages with the above fix and a few others are being
released now as lam*-6.2b-pl4-2. Please test.
Another individual suggested increasing the IPC resources. This had
no effect on this issue.
Take care,
