Hello everybody,
just to bring this to some conclusion for other people who might
eventually find this thread.
I tried several times to submit a message to the scalapack/lapack forum.
However, regardless what I do my message gets flagged as spam and is
denied. An strongly abbreviated message got
Hello,
thank you very much for your input. I will then certainly contact the
scalapack list after making sure this is not a problem with the
lapack/blas libraries and making tests with mvapich on the workstation
and laptop.
I should have made the workstation/laptop test earlier. But at

Christof,
Don't use "-ffpe-trap=invalid,zero,overflow" on the pdlaiect.f file. This

Hello everybody,
as promised I started to test on my laptop (which has only two physical
cores, in case that matters).
As I discovered the story is not as simple as I assumed. I was focusing
on xdsyevr when testing on the workstation and overlooked the others.
On the cluster the only test which

No, at least not for the workstation example. I will test with my laptop
(debian stable) tomorrow.
Thank you all
Christoph,
out of curiosity, could you try to
mpirun --mca coll ^tuned ...
and see if it helps ?

Hello again,
I tried to replicate the situation on the workstation at my desk,
running ubuntu 14.04 (gcc 4.8.4) and with the OS supplied lapack and
blas libraries.
With openmpi 2.0.1 (mpirun -np 4 xdsyevr) I get "136 tests completed and
failed." with the "IL, IU, VL or VU altered by PDSYEVR" mes

Hello,
I tried
mpirun -n 4 --mca pml ob1 -x PATH -x
d residual checks.
0 tests completed without checking.
0 tests skipped for lack of memory.
0 tests completed and failed.

Hi Christof,
Thanks for trying out 2.0.1. Sorry that you're hitting problems.
Could you try to run the tests using the 'ob1' PML in order to
bypass PSM2?
mpirun --mca pml ob1 (all the rest of the args)
and see if you still observe the failures?

Hello everybody,
I am observing failures in the xdsyevr (and xssyevr) ScaLapack self
tests when running on one or two nodes with OpenMPI 2.0.1. With 1.10.4
no failures are observed. Also, with mvapich2 2.2 no failures are
observed.
The other testers appear to be working with all MPIs mentio
