[Bug 508575] [NEW] scalapack package fails test from test-suite.

[it's me]

Public bug reported:

lsb_release -rd
Description:    Ubuntu 9.10
Release:        9.10

 apt-cache policy libscalapack-mpi1
libscalapack-mpi1:
  Installed: 1.8.0-3.1build1
  Candidate: 1.8.0-3.1build1
  Version table:
 *** 1.8.0-3.1build1 0

After installing  the test-suite (scalapack-mpi-test) and running examples get a segmentation fault (see below). I am not certain where the problem is - but could be with blacs and/or blas implementation which scalapack relies on.

NOTE: scalapack-mpi-test is actually incomplete, and only the binaries
are included - but not the data files which are needed by the boundaries
to run... i got those from the source package of scalapack.

Running tests of the parallel symmetric eigenvalue routine:  PDSYEVX &  PDSYEV & PDSYEVD.
The following scaled residual checks will be computed:
 ||AQ - QL|| / ((abstol + ||A|| * eps) * N)
 ||Q^T*Q - I|| / (N * eps)

An explanation of the input/output parameters follows:
RESULT   : passed; or an indication of which eigen request test failed
N        : The number of rows and columns of the matrix A.
P        : The number of process rows.
Q        : The number of process columns.
NB       : The size of the square blocks the matrix A is split into.
THRESH   : If a residual value is less than THRESH, RESULT is flagged as PASSED.
         : the QTQ norm is allowed to exceed THRESH for those eigenvectors
         :  which could not be reorthogonalized for lack of workspace.
TYP      : matrix type (see PDSEPtst.f).
SUB      : Subtests (see PDSEPtst).f
CHK      : ||AQ - QL|| / ((abstol + ||A|| * eps) * N)
QTQ      : ||Q^T*Q - I||/ (N * eps)
         : when the adjusted QTQ exceeds THRESH
 the adjusted QTQ norm is printed
         : otherwise the true QTQ norm is printed
           If NT>1, CHK and QTQ are the max over all eigen request tests
TEST     : EVX - testing PDSYEVX, EV - testing PDSYEV, EVD - testing PDSYEVD
