Known Issues

Binary installation issues

Cross Platform

Red Hat (and clones) specific

  • The DM codebase is not compatible with the Intel Math Kernel Library (MKL). Attempting to use MKL may generate incorrect numerical results.

    If you have installed using Conda, you should install the nomkl package, and remove mkl and mkl service. :jirab:`DM-5105`

Source installation issues

Cross Platform

  • Compiling some packages---in particular afw---require large amounts of RAM to compile. This is compounded as the system will automatically attempt to parallelize the build, and can cause the build to run extremely slowly or fail altogether. On machines with less than 8 GB of RAM, disable parallelization by setting EUPSPKG_NJOBS=1 in your environment before running eups distrib.

Red Hat (and clones) specific

RHEL 7.*

  • No specific issues.

RHEL 6.*

macOS specific

macOS 10.13 (Sierra) and OS X 10.11 (El Capitan)

Older systems

  • Some old installations of XCode on Macs create a :file:`/Developer` directory.  This can interfere with installation.
