HPX V0.9.11 (Nov 11, 2015)¶
Our main focus for this release was the design and development of a coherent set
of higher-level APIs exposing various types of parallelism to the application
programmer. We introduced the concepts of an executor
, which can be used to
customize the where
and when
of execution of tasks in the context of
parallelizing codes. We extended all APIs related to managing parallel tasks to
support executors which gives the user the choce of either using one of the
predefined executor types or to provide its own, possibly application specific,
executor. We paid very close attention to align all of these changes with the
existing C++ Standards documents or with the ongoing proposals for
standardization.
This release is the first after our change to a new development policy. We
switched all development to be strictly performed on branches only, all direct
commits to our main branch (master
) are prohibited. Any change has to go
through a peer review before it will be merged to master
. As a result the
overall stability of our code base has significantly increased, the development
process itself has been simplified. This change manifests itself in a large
number of pull-requests which have been merged (please see below for a full list
of closed issues and pull-requests). All in all for this release, we closed
almost 100 issues and merged over 290 pull-requests. There have been over 1600
commits to the master branch since the last release.
General changes¶
- We are moving into the direction of unifying managed and simple components. As
such, the classes
hpx::components::component
andhpx::components::component_base
have been added which currently just forward to the currently existing simple component facilities. The examples have been converted to only use those two classes. - Added integration with the CircleCI hosted continuous integration service. This gives us constant and immediate feedback on the health of our master branch.
- The compiler configuration subsystem in the build system has been reimplemented. Instead of using Boost.Config we now use our own lightweight set of cmake scripts to determine the available language and library features supported by the used compiler.
- The API for creating instances of components has been consolidated. All
component instances should be created using the
hpx::new_
only. It allows to instantiate both, single component instances and multiple component instances. The placement of the created components can be controlled by special distribution policies. Please see the corresponding documentation outlining the use ofhpx::new_
. - Introduced four new distribution policies which can be used with many API
functions which traditionally expected to be used with a locality id. The new
distribution policies are:
hpx::components::default_distribution_policy
which tries to place multiple component instances as evenly as possible.hpx::components::colocating_distribution_policy
which will refer to the locality where a given component instance is currently placed.hpx::components::binpacking_distribution_policy
which will place multiple component instances as evenly as possible based on any performance counter.hpx::components::target_distribution_policy
which allows to represent a given locality in the context of a distrwibution policy.
- The new distribution policies can now be also used with
hpx::async
. This change also deprecateshpx::async_colocated(id, ...)
which now is replaced by a distribution policy:hpx::async(hpx::colocated(id), ...)
. - The
hpx::vector
andhpx::unordered_map
data structures can now be used with the new distribution policies as well. - The parallel facility
hpx::parallel::task_region
has been renamed tohpx::parallel::task_block
based on the changes in the corresponding standardization proposal N4411. - Added extensions to the parallel facility
hpx::parallel::task_block
allowing to combine a task_block with an execution policy. This implies a minor breaking change as thehpx::parallel::task_block
is now a template. - Added new LCOs:
hpx::lcos::latch
andhpx::lcos::local::latch
which semantically conform to the proposedstd::latch
(see N4399). - Added performance counters exposing data related to data transferred by input/output (filesystem) operations (thanks to Maciej Brodowicz).
- Added performance counters allowing to track the number of action invocations (local and remote invocations).
- Added new command line options –hpx:print-counter-at and –hpx:reset-counters.
- The
hpx::vector
component has been renamed tohpx::partitioned_vector
to make it explicit that the underlying memory is not contiguous. - Introduced a completely new and uniform higher-level parallelism API which is based on executors. All existing parallelism APIs have been adapted to this. We have added a large number of different executor types, such as a numa-aware executor, a this-thread executor, etc.
- Added support for the MingW toolchain on Windows (thanks to Eric Lemanissier).
- HPX now includes support for APEX, (Autonomic Performance Environment for
eXascale). APEX is an instrumentation and software adaptation library that
provides an interface to TAU profiling / tracing as well as runtime adaptation
of HPX applications through policy definitions. For more information and
documentation, please see https://github.com/khuck/xpress-apex. To enable APEX
at configuration time, specify
-DHPX_WITH_APEX=On
. To also include support for TAU profiling, specify-DHPX_WITH_TAU=On
and specify the-DTAU_ROOT
,-DTAU_ARCH
and-DTAU_OPTIONS
cmake parameters. - We have implemented many more of the Using parallel algorithms. Please see Issue #1141 for the list of all available parallel algorithms (thanks to Daniel Bourgeois and John Biddiscombe for contributing their work).
Breaking changes¶
- We are moving into the direction of unifying managed and simple components. In
order to stop exposing the old facilities, all examples have been converted to
use the new classes. The breaking change in this release is that performance
counters are now a
hpx::components::component_base
instead ofhpx::components::managed_component_base
. - We removed the support for stackless threads. It turned out that there was no performance benefit when using stackless threads. As such, we decided to clean up our codebase. This feature was not documented.
- The CMake project name has changed from ‘hpx’ to ‘HPX’ for consistency and compatibilty with naming conventions and other CMake projects. Generated config files go into <prefix>/lib/cmake/HPX and not <prefix>/lib/cmake/hpx.
- The macro
HPX_REGISTER_MINIMAL_COMPONENT_FACTORY
has been deprecated. Please useHPX_REGISTER_COMPONENT
. instead. The old macro will be removed in the next release. - The obsolete distributing_factory and binpacking_factory components have been
removed. The corresponding functionality is now provided by the
hpx::new_
API function in conjunction with thehpx::default_layout
andhpx::binpacking
distribution policies (hpx::components::default_distribution_policy
andhpx::components::binpacking_distribution_policy
) - The API function
hpx::new_colocated
has been deprecated. Please use the consolidated APIhpx::new_
in conjunction with the newhpx::colocated
distribution policy (hpx::components::colocating_distribution_policy
) instead. The old API function will still be available for at least one release of HPX if the configuration variableHPX_WITH_COLOCATED_BACKWARDS_COMPATIBILITY
is enabled. - The API function
hpx::async_colocated
has been deprecated. Please use the consolidated APIhpx::async
in conjunction with the newhpx::colocated
distribution policy (hpx::components::colocating_distribution_policy
) instead. The old API function will still be available for at least one release of HPX if the configuration variableHPX_WITH_COLOCATED_BACKWARDS_COMPATIBILITY
is enabled. - The obsolete remote_object component has been removed.
- Replaced the use of Boost.Serialization with our own solution. While the new version is mostly compatible with Boost.Serialization, this change requires some minor code modifications in user code. For more information, please see the corresponding announcement on the hpx-users@stellar.cct.lsu.edu mailing list.
- The names used by cmake to influence various configuration options have been
unified. The new naming scheme relies on all configuration constants to start
with
HPX_WITH_...
, while the preprocessor constant which is used at build time starts withHPX_HAVE_...
. For instance, the former cmake command line-DHPX_MALLOC=...
now has to be specified a-DHPX_WITH_MALLOC=...
and will cause the preprocessor constantHPX_HAVE_MALLOC
to be defined. The actual name of the constant (i.e.MALLOC
) has not changed. Please see the corresponding documentation for more details (CMake variables used to configure HPX). - The
get_gid()
functions exposed by the component base classeshpx::components::server::simple_component_base
,hpx::components::server::managed_component_base
, andhpx::components::server::fixed_component_base
have been replaced by two new functions:get_unmanaged_id()
andget_id()
. To enable the old function name for backwards compatibility, use the cmake configuration optionHPX_WITH_COMPONENT_GET_GID_COMPATIBILITY=On
. - All functions which were named
get_gid()
but were returninghpx::id_type
have been renamed toget_id()
. To enable the old function names for backwards compatibility, use the cmake configuration optionHPX_WITH_COMPONENT_GET_GID_COMPATIBILITY=On
.
