Summary
|
||
|
|
Thrust 1.7.0 introduces a new interface for controlling algorithm execution as
|
||
|
|
well as several new algorithms and performance improvements. With this new
|
||
|
|
interface, users may directly control how algorithms execute as well as details
|
||
|
|
such as the allocation of temporary storage. Key/value versions of thrust::merge
|
||
|
|
and the set operation algorithms have been added, as well stencil versions of
|
||
|
|
partitioning algorithms. thrust::tabulate has been introduced to tabulate the
|
||
|
|
values of functions taking integers. For 32b types, new CUDA merge and set
|
||
|
|
operations provide 2-15x faster performance while a new CUDA comparison sort
|
||
|
|
provides 1.3-4x faster performance. Finally, a new TBB reduce_by_key implementation
|
||
|
|
provides 80% faster performance.
|
||
|
|
|
||
|
|
Breaking API Changes
|
||
|
|
Dispatch
|
||
|
|
Custom user backend systems' tag types must now inherit from the corresponding system's execution_policy template (e.g. thrust::cuda::execution_policy) instead
|
||
|
|
of the tag struct (e.g. thrust::cuda::tag). Otherwise, algorithm specializations will silently go unfound during dispatch.
|
||
|
|
See examples/minimal_custom_backend.cu and examples/cuda/fallback_allocator.cu for usage examples.
|
||
|
|
|
||
|
|
thrust::advance and thrust::distance are no longer dispatched based on iterator system type and thus may no longer be customized.
|
||
|
|
|
||
|
|
Iterators
|
||
|
|
iterator_facade and iterator_adaptor's Pointer template parameters have been eliminated.
|
||
|
|
iterator_adaptor has been moved into the thrust namespace (previously thrust::experimental::iterator_adaptor).
|
||
|
|
iterator_facade has been moved into the thrust namespace (previously thrust::experimental::iterator_facade).
|
||
|
|
iterator_core_access has been moved into the thrust namespace (previously thrust::experimental::iterator_core_access).
|
||
|
|
All iterators' nested pointer typedef (the type of the result of operator->) is now void instead of a pointer type to indicate that such expressions are currently impossible.
|
||
|
|
Floating point counting_iterators' nested difference_type typedef is now a signed integral type instead of a floating point type.
|
||
|
|
|
||
|
|
Other
|
||
|
|
normal_distribution has been moved into the thrust::random namespace (previously thrust::random::experimental::normal_distribution).
|
||
|
|
Placeholder expressions may no longer include the comma operator.
|
||
|
|
|
||
|
|
New Features
|
||
|
|
Execution Policies
|
||
|
|
Users may directly control the dispatch of algorithm invocations with optional execution policy arguments.
|
||
|
|
For example, instead of wrapping raw pointers allocated by cudaMalloc with thrust::device_ptr, the thrust::device execution_policy may be passed as an argument to an algorithm invocation to enable CUDA execution.
|
||
|
|
The following execution policies are supported in this version:
|
||
|
|
|
||
|
|
thrust::host
|
||
|
|
thrust::device
|
||
|
|
thrust::cpp::par
|
||
|
|
thrust::cuda::par
|
||
|
|
thrust::omp::par

New Examples
|
||
|
|
uninitialized_vector demonstrates how to use a custom allocator to avoid the automatic initialization of elements in thrust::device_vector.
|
||
|
|
|
||
|
|
Other Enhancements
|
||
|
|
Authors of custom backend systems may manipulate arbitrary state during algorithm dispatch by incorporating it into their execution_policy parameter.
|
||
|
|
Users may control the allocation of temporary storage during algorithm execution by passing standard allocators as parameters via execution policies such as thrust::device.
|
||
|
|
THRUST_DEVICE_SYSTEM_CPP has been added as a compile-time target for the device backend.
|
||
|
|
CUDA merge performance is 2-15x faster.
|
||
|
|
CUDA comparison sort performance is 1.3-4x faster.
|
||
|
|
CUDA set operation performance is 1.5-15x faster.
|
||
|
|
TBB reduce_by_key performance is 80% faster.
|
||
|
|
Several algorithms have been parallelized with TBB.
|
||
|
|
Support for user allocators in vectors has been improved.
|
||
|
|
The sparse_vector example is now implemented with merge_by_key instead of sort_by_key.
|
||
|
|
Warnings have been eliminated in various contexts.
|
||
|
|
Warnings about __host__ or __device__-only functions called from __host__ __device__ functions have been eliminated in various contexts.
|
||
|
|
Documentation about algorithm requirements have been improved.
|
||
|
|
Simplified the minimal_custom_backend example.
|
||
|
|
Simplified the cuda/custom_temporary_allocation example.
|
||
|
|
Simplified the cuda/fallback_allocator example.

|
Summary
|
||
|
|
Thrust v1.6.0 provides an interface for customization and extension and a new
|
||
|
|
backend system based on the Threading Building Blocks library. With this
|
||
|
|
new interface, programmers may customize the behavior of specific algorithms
|
||
|
|
as well as control the allocation of temporary storage or invent entirely new
|
||
|
|
backends. These enhancements also allow multiple different backend systems
|
||
|
|
such as CUDA and OpenMP to coexist within a single program. Support for TBB
|
||
|
|
allows Thrust programs to integrate more naturally into applications which
|
||
|
|
may already employ the TBB task scheduler.

|
Summary
|
||
|
|
Thrust v1.5.0 provides introduces new programmer productivity and performance
|
||
|
|
enhancements. New functionality for creating anonymous "lambda" functions has
|
||
|
|
been added. A faster host sort provides 2-10x faster performance for sorting
|
||
|
|
arithmetic types on (single-threaded) CPUs. A new OpenMP sort provides
|
||
|
|
2.5x-3.0x speedup over the host sort using a quad-core CPU. When sorting
|
||
|
|
arithmetic types with the OpenMP backend the combined performance improvement
|
||
|
|
is 5.9x for 32-bit integers and ranges from 3.0x (64-bit types) to 14.2x
|
||
|
|
(8-bit types). A new CUDA reduce_by_key implementation provides 2-3x faster
|
||
|
|
performance.
|
||
|
|
|
||
|
|
Breaking API Changes
|
||
|
|
device_ptr<void> no longer unsafely converts to device_ptr<T> without an
|
||
|
|
explicit cast. Use the expression
|
||
|
|
device_pointer_cast(static_cast<int*>(void_ptr.get()))
|
||
|
|
to convert, for example, device_ptr<void> to device_ptr<int>.

|
|
Summary
|
||
|
|
Thrust v1.3.0 provides support for CUDA 3.2 in addition to many feature
|
||
|
|
and performance enhancements.
|
||
|
|
|
||
|
|
Performance of the sort and sort_by_key algorithms is improved by as much
|
||
|
|
as 3x in certain situations. The performance of stream compaction algorithms,
|
||
|
|
such as copy_if, is improved by as much as 2x. Reduction performance is
|
||
|
|
also improved, particularly for small input sizes.
|
||
|
|
|
||
|
|
CUDA errors are now converted to runtime exceptions using the system_error
|
||
|
|
interface. Combined with a debug mode, also new in v1.3, runtime errors
|
||
|
|
can be located with greater precision.
|
||
|
|
|
||
|
|
Lastly, a few header files have been consolidated or renamed for clarity.
|
||
|
|

|
Summary
|
||
|
|
Thrust v1.2 introduces support for compilation to multicore CPUs
|
||
|
|
and the Ocelot virtual machine, and several new facilities for
|
||
|
|
pseudo-random number generation. New algorithms such as set
|
||
|
|
intersection and segmented reduction have also been added. Lastly,
|
||
|
|
improvements to the robustness of the CUDA backend ensure
|
||
|
|
correctness across a broad set of (uncommon) use cases.
|
||
|
|
|
||
|
|
Breaking API Changes
|
||
|
|
thrust::gather's interface was incorrect and has been removed.
|
||
|
|
The old interface is deprecated but will be preserved for Thrust
|
||
|
|
version 1.2 at thrust::deprecated::gather &
|
||
|
|
thrust::deprecated::gather_if. The new interface is provided at
|
||
|
|
thrust::next::gather & thrust::next::gather_if. The new interface
|
||
|
|
will be promoted to thrust:: in Thrust version 1.3. For more details,
|
||
|
|
please refer to this thread:
|
||
|
|
http://groups.google.com/group/thrust-users/browse_thread/thread/f5f0583cb97b51fd
|
||
|
|
|
||
|
|
The thrust::sorting namespace has been deprecated in favor of the
|
||
|
|
top-level sorting functions, such as thrust::sort() and
|
||
|
|
thrust::sort_by_key().

|
|
# 102 eliminated a race condition in device_vector::erase
|

Breaking API changes
|
||
|
|
Rename top level namespace komrade to thrust.
|
||
|
|
Move partition_copy() & stable_partition_copy() into thrust::experimental namespace until we can easily provide the standard interface.
|
||
|
|
Rename range() to sequence() to avoid collision with Boost.Range.
|
||
|
|
Rename copy_if() to copy_when() due to semantic differences with C++0x copy_if().
|
||
|
|
|
||
|
|
New Features
|
||
|
|
Add C++0x style cbegin() & cend() methods to host_vector & device_vector.
|
||
|
|
Add transform_if function.
|
||
|
|
Add stencil versions of replace_if() & replace_copy_if().
|
||
|
|
Allow counting_iterator to work with for_each().
|
||
|
|
Allow types with constructors in comparison sort & reduce.
|
||
|
|
|
||
|
|
Other Enhancements
|
||
|
|
merge_sort and stable_merge_sort are now 2 to 5x faster when executed on the parallel device.
|
||
|
|
|
||
|
|
Bug fixes
|
||
|
|
Workaround an issue where an incremented iterator causes nvcc to crash. (Komrade issue #6)
|
