This document summarizes the efforts of current and future xSDK member packages to achieve compatibility with the xSDK community policies. Below only short descriptions of each policy are provided. The full description is available here and should be considered when filling out this form.
Please, provide information on your Compatibility status for each mandatory policy, and if possible also for recommended policies. If you are not compatible, state what is lacking and what are your plans on how to achieve compliance. For current xSDK member packages: If you were not compliant at some point, please describe the steps you undertook to fulfill the policy.This information will be helpful for future xSDK member packages.

| Policy | Support | Notes |
|---|---|---|
| M1. Support xSDK community GNU Autoconf or CMake options. | Full | Tasmanian uses the CMake options. |
| M2. Provide a comprehensive test suite for correctness of installation verification. | Full | Tasmanian has a comprehensive test suites covering all major functionality, code coverage is checked daily. |
| M3. Employ user provided MPI communicator (no MPI_COMM_WORLD). | Full | Overall, Tasmanian provides little MPI functionaily, but all of it is restricted to a user specified MPI_COMM |
| M4. Give best effort at portability to key architectures (standard Linux distributions, GNU, Clang, vendor compilers, and target machines at ALCF, NERSC, OLCF). | Full | Tasmanian CI includes both gcc and clang, all releases are tested on the aforementioned DoE machines. In addition, Mac OSX and MS Windows are fully supported as well. |
| M5. Provide a documented, reliable way to contact the development team. | Full | The manual and the web-page list the Lead Developer e-mail. Github issues are also accepted. |
| M6. Respect system resources and settings made by other previously called packages (e.g. signal handling). | Full | Currently Tasmanian doesn't modify anything related to signal handling. |
| M7. Come with an open source (BSD style) license. | Full | Tasmanian is distributed under 3-Clause BSD license with an additional UT-Battelle disclaimer (redundantly confirming that the software is provided AS IS). |
| M8. Provide a runtime API to return the current version number of the software. | Full | Tasmanian has static int TasGrid::TasmanianSparseGrid::getVersionMajor(), also getVersionMinor(), getGitCommitHash(), and getCmakeCxxFlags(). The information is also provided by the CLI tool tasgrid -version. |
| M9. Use a limited and well-defined symbol, macro, library, and include file name space. | Full | Everything in Tasmanian is encapsulated in C++ TasGrid and TasDREAM namespaces, the ANSI C and Fortran 90 interfaces use the prefix tsg. Similarly, files use tsg (Tasmanian Sparse Grids) tdr (Tasmanian DREAM), or just Tasmanian prefixes. |
| M10. Provide an xSDK team accessible repository (not necessarily publicly available). | Full | https://github.com/ORNL/TASMANIAN is publicly available. |
| M11. Have no hardwired print or IO statements that cannot be turned off. | Full | Tasmanian is silent, unless the user explicitly asks for output. |
| M12. For external dependencies, allow installing, building, and linking against an outside copy of external software. | Full | Tasmanian uses CMake find_package() modules, and external libraries such as BLAS and MAGMA can be specified directly. |
| M13. Install headers and libraries under <prefix>/include and <prefix>/lib. | Full | Libraries and headers go in <prefix>/lib and <prefix>/include, CLI tools sit in <prefix>/bin, scripts and auxilary files go in <prefix>/share/Tasmanian. |
| M14. Be buildable using 64 bit pointers. 32 bit is optional. | Full | CI and nighly builds are done in 64-bit mode, 32-bit might work but is not tested or supported. |
| M15. All xSDK compatibility changes should be sustainable. | Full | XSDK optins are integrated in the build system and will be supported in the foreseeable futire. |
| M16. The package must support production-quality installation compatible with the xSDK install tool and xSDK metapackage. | Full | The Spack package for Tasmanian accepts +xsdkflags, and is already included in the xSDK package.py. |
| Policy | Support | Notes |
|---|---|---|
| R1. Have a public repository. | Full | https://github.com/ORNL/TASMANIAN |
| R2. Possible to run test suite under valgrind in order to test for memory corruption issues. | Full | Tasmanian is tested under valgrind on a daily basis. |
| R3. Adopt and document consistent system for error conditions/exceptions. | Full | Documented C++ and Python exceptions are extensively used in the respective interfaces; command line and MATLAB interfaces come with comprehensive error messages. |
| R4. Free all system resources acquired as soon as they are no longer needed. | Full | Memory leaks tested daily with valgrind. Prompt release of resource is integrated in the library design. |
| R5. Provide a mechanism to export ordered list of library dependencies. | Full | The spack package provides a full list of dependencies, the manual lists all tested compilers and libraries. |
| R6. Document versions of packages that it works with or depends upon, preferably in machine-readable form. | Partial | The detailed installation instructions come with a full list of tested external dependencies (available on github and doxygen, but not machine readable). |
| R7. Have README, SUPPORT, LICENSE, and CHANGELOG files in top directory. | Full | All files are included in the repository. |
