Project Description
Dynamic Probe Class Library (DPCL) is an
object based C++ class library
that provides
the necessary infrastructure
to allow tool
developers and sophisticated
tool users to
build parallel and serial tools
through technology
called dynamic instrumentation.
DPCL takes the basic components needed by
tool developers and encapsulates
them into
C++ classes. Each of these classes
provide
the member functions necessary
to interact
and dynamically instrument a
running application
with software patches called
probes. Dynamic instrumentation provides the flexibility
for tools to insert probes into
applications
as the application is running
and only where
it is needed.
What are the benefits? If you
are a tool
developer, you can focus on developing
tools
that address the requirement
you are trying
to fulfill. You don't have to
worry about
the low level details of individual
compilers.
You don't have to build the distributed
infrastructure
to support your tool. If you
are a researcher,
you can focus your time on the
problem you
are trying to research. Trial
and error is
less costly. If you need specialized
tools,
you can develop them in-house
with less effort.
If you are a tool user, you will
ultimately
have better tools, portable tools
and more
choices.
Ptools Project
DPCL is an official Parallel Tools Consortium project.
Developing DPCL
DPCL is licensed under the IBM Public License. If there's a feature that you'd like to
see added to DPCL, consider becoming
a part
of the DPCL development process.
Since DPCL
is an open source project, it's
easy to get
involved.
DPCL Releases
There are two releases available for DPCL.
The 3.2.* release stream is intended for
use in a DPCL production environment, such
as with PE Benchmarker. The 3.3.* release
stream is currently intended for development
use only and has not been extensively tested.
The 3.3.* release stream will become a production
release stream at a to be determined date
in the future.
DPCL Core Team
The DPCL project is managed by a small, core
group of contributors known as
the DPCL core
team. In addition to having read-write
access
to the DPCL source code repository,
this
group has the following responsibilities:
- Deciding which
features go into which releases
- Deciding who has access to the DPCL source
code repository
- Approving the
check-in of new or changed source code and
documentation
- Appointing new
members of the core team
The current members of the DPCL core team
are:
