This is a start of moving the VTK-m User's Guide into the VTK-m source.
This is only the start of the process. There are several goals of this
work.
1. Integrate the documentation into the source code better to better
keep the code up to date.
2. Move the documentation over to Sphinx so that it can be posted online
and be more easily linked.
3. Incoporate Doxygen into the guide to keep the documentation
consistent.
4. Build the user guide examples as part of the VTK-m CI to catch
compatibility changes quickly.
There are numerous scripts and configuration files defined in the CI setup
and elsewhere that were missing the copyright statement. Add more types
of files to check in the CopyrightStatement test, and update the files
with the appropriate statement.
GCC 11 is having trouble compiling brigand.hpp at all, even before we
instantiate any templates. Since we no longer need it, let's get rid of
it. It was always placed in an internal namespace.
Do not check for the copyright statement for files in the third party
directory. These files shouldn't have the VTK-m copyright. Frankly, I
don't understand why this has not been a problem before.
Parallel radix sorting will be invoked in DeviceAdapterAlgorthmTBB.h when
the input is ArrayHandle<T, vtkm::cont::StorageTagBasic> where T is one of
the following basic C++ types:
unsigned int
unsigned short int
unsigned long int
unsigned long long int
unsigned char
char16_t
char32_t
wchar_t
char
short
int
long long
signed char
float
double
If a comparison operator is provided, it must be type std::less<T> or std::greater<T>.
Radix sort implementation is Satish parallel radix sort as documented in the
following citation:
Fast sort on CPUs and GPUs: a case for bandwidth oblivious SIMD sort.
N. Satish, C. Kim, J. Chhugani, A. D. Nguyen, V. W. Lee, D. Kim, and P. Dubey.
In Proc. SIGMOD, pages 351–362, 2010
Implementation is based on Takuya Akiba's GitHub source code with the following
changes:
- Changed parallel threading from OpenMP to TBB tasks
- Removed pair sorting
- Added minimum threshold for parallel, will instead invoke serial radix sort (kxsort)
- Added std::greater<T> and std::less<T> to interface for descending order sorts
- Added can_use_parallel_radix_sort<T, F>() function to determine if parallel radix sorting
is possible for type T and compare function F (fallback is std::sort() if not possible)
- Added linear scaling of threads used by the algorithm for more stable performance
on machines with lots of available threads (KNL and Haswell)
Added kxsort (serial MSD radix sort by Dinghua Li via GitHub) implementation without modification.
Sandia National Laboratories recently changed management from the
Sandia Corporation to the National Technology & Engineering Solutions
of Sandia, LLC (NTESS). The copyright statements need to be updated
accordingly.
