OS: FreeBSD 12.1 Version 2.0.2 ``` Error: /usr/local/lib/libscalapack.so.2 is linked to /usr/local/lib/libmpi.so.12 from net/mpich but it is not declared as a dependency Warning: you need LIB_DEPENDS+=libmpi.so:net/mpich ```
There are some building blocks (like reduction to Hessenberg and Schur) making it possible to solve this problem in ScaLAPACK. But at the same time, there is no driver. It...
This is a gap in ScaLAPACK API.
This is a gap in ScaLAPACK API: it makes using P?GEBAL routine problematic.
This is a gap in ScaLAPACK API: it makes problematic to compute the eigenvalues of a real unsymmetrical matrix.
This is a gap in ScaLAPACK API. The link below shows that HSEQR performs much faster than LAHQR. It means that ScaLAPACK implements an inefficient algorithm for complex matrices. http://netlib.org/scalapack/scalapack-2.0.0.html
Inside `pdstedc` function `pdlasrt` is called with passing of `lwork`. But: `lwmin` for the 1st one is ``` 6*n + 2*np*nq ``` while `lwmin` for the 2nd function is ```...
There is a 2.2.1 tag since almost two years (https://github.com/Reference-ScaLAPACK/scalapack/releases/tag/v2.2.1) but neither a GitHub release nor a tarball for download on https://www.netlib.org/scalapack. Is it recommended to use 2.2.1 from the...
Summary: I found an erroneous output when calling `pdlapv2` with the following reproducible example. With inspection of the source code `pdlapv2.f` I think it's an algorithm error. (Or I misunderstood...
I tried building with these flags to optimize my build using LTO: `-flto=4 -Werror=odr -Werror=lto-type-mismatch -Werror=strict-aliasing` I got these errors: ``` [1/887] Building C object CMakeFiles/scalapack.dir/SRC/pdlaiect.c.o FAILED: CMakeFiles/scalapack.dir/SRC/pdlaiect.c.o /usr/bin/mpicc -DAdd_...
