Free hpc toolkit software for linux

HPCToolkit is an open-source suite of multi-platform tools for profile-based performance analysis of applications. The figure provides an overview of the toolkit components and their relationships.
Main features:
- hpcrun: a tool for profiling executions of unmodified application binaries using statistical sampling of hardware performance counters.
- hpcprof & xprof: tools for interpeting sample-based execution profiles and relating them back to program source lines.
- bloop: a tool for analyzing application binaries to recover program structure; namely, to identify where loops are present and what program source lines they contain.
- hpcview: a tool for correlating program structure information, multiple sample-based performance profiles, and program source code to produce a performance database.
- hpcviewer: a java-based GUI for exploring databases consisting of performance information correlated with program source.
A program called hpcview is at the toolkits center. It takes performance profiles, program structure information, and, under the direction of a configuration file, correlates it with application source code to produce a browsable performance database.
hpcview also enables the user to define expressions to compute derived metrics as functions other metrics already defined (e.g. measured metrics read from data files or previously-computed derived metrics).
Performance databases are explored using our Java-based hpcviewer user interface that enables one to explore an applications performance data in a top-down fashion and enables one to easily navigate back and forth between performance data and source code.
The user interface presents performance data in a hierarchical display. At any time, you are looking at some program context (program, file, procedure, loop, or line). Also displayed is the data for both the parent and the children of the current context. Up and down arrows on the lines of the display are used to walk the hierarchy.
In order to speed up top-down analysis, the interface also provides `flatten and `un-flatten buttons. Their icons hint at their function. `Flatten modifies the hierarchy by eliding non-leaf children of the current node and replacing them with the grandchildren.
Unflatten reverses this. Since the tables are sorted, the flatten operation makes short work of diving into the program from the top to identify the most important files, procedures, loops and statements.
Performance data manipulated by hpcview can come from any source, as long as the profile data can be translated or saved directly to a standard, profile-like input format. To date, the principal sources of input data for hpcview have been hardware performance counter profiles.
Such profiles are generated by setting up a hardware counter to monitor events of interest (e.g., primary cache misses), to generate a trap when the counter overflows, and then to histogram the program counter values at which these traps occur. For Linux, we developed the hpcrun tool to collect profiles by sampling hardware performance counters.
This tool uses UTKs PAPI library for access to hardware performance counters. A second tool, hpcprof is used to map profiles collected using hpcrun back to program source lines. hpcprof is based on code from Curt Janssens cprof/vprof profiler. On operating systems other than Linux, we use vendor-supplied tools to collect profile data. On MIPS+Irix platforms, we use SGIs ssrun tool to collect profiles. On Alpha+Tru64, we use either with Compaqs uprofile or DCPI utilities for this purpose.
hpcview and hpcviewer can be used to view profile-like data of any type, not just data sampled from hardware performance counters. To analyze one program that contained many register spills, we built a perl script to examine assembly code generated by the SGI compilers for MIPS+Irix and create profiles that map register spills back to source code lines.
To facilitate automation, the programs in HPCToolkit are intended to be run using scripts and configuration files. Once these are set up, rerunning the program to collect new data, and all of the steps that go into generating a browsable dataset can be completely automated. The scripts automate the collection of data and conversion of profile data into a common, XML-based format.
Other performance tools (e.g. SGIs ssrun) report performance data at the line, procedure, and program level. However, since much of the time in scientific programs is spent in loops; having data at the loop level as well is critical to facilitate performance tuning.
For this reason, HPCToolkit includes a binary analyzer bloop that extracts loop nesting structure from application binaries and uses symbol table line map information to map this structure back to the source programs level. Because bloop works on binaries, this process is independent of the language used (though in practice it can be somewhat compiler dependent).
The loop nesting structure information produced by bloop enables hpcview to associate performance data with each loop in a program without incurring any additional overhead for data collection during program execution.
Supported platforms: Pentium+Linux, Opteron+Linux, Athlon+Linux, Itanium+Linux, Alpha+Tru64 and MIPS+Irix.
HPCToolkit is open-source software released with a BSD-like license.

Mimas Toolkit is a C++ computer vision toolkit. It is easy to use and includes tools for edge detection, corner detection, various filters, optic flow, tracking, blob analysis, Web cam tools for real-time applications, and much more.
Mimas Toolkit project also includes many implementations of traditional algorithms such as Canny. It was developed for GNU/Linux but as the GUI is largely separate, porting to other platforms should be straightforward.
Mimas was originally conceived as a platform for real-time machine vision research. Its aim was and still is to reduce the turnaround time of new research into the application workspace. It is written in C++ and is released in source code form subject to the GNU Lesser General Public License (LGPL).
Mimas has been used to build a number of vision systems including for two European Union sponsored projects, namely MINIMAN (completed in 2002) and MiCRoN (expected to complete in the 3rd quarter of 2005). Mimas is also being used to build a number of customised vision solutions for academia and industry. As such, if you do require a vision-based solution then please contact the authors of this software.
Main features:
- generic image class (greylevel and colour)
- low level image processing
- frequency domain processing
- variety of recognition methods
- variety of tracking methods
- active contours
- comprehensive matrix library
- variety of statistical operations
- associative neural network
- multi-layer perceptrons ANN
- image capture
- various example interfaces
Mimas is designed to be platform independent from the ground-up. Hence a user interface is not built-in. Rather Mimas acts as the engine of a vision system. Since it is written in C++, we recommend that you use the GPL-ed version of the cross-platform Qt toolkit or the Mozilla XP toolkit for building user interfaces.

Globus Toolkit is an open source software toolkit used for building grids. It is being developed by the Globus Alliance and many others all over the world.
A growing number of projects and companies are using the Globus Toolkit to unlock the potential of grids for their cause.
The open source Globus Toolkit is a fundamental enabling technology for the "Grid," letting people share computing power, databases, and other tools securely online across corporate, institutional, and geographic boundaries without sacrificing local autonomy. The toolkit includes software services and libraries for resource monitoring, discovery, and management, plus security and file management. In addition to being a central part of science and engineering projects that total nearly a half-billion dollars internationally, the Globus Toolkit is a substrate on which leading IT companies are building significant commercial Grid products.
The toolkit includes software for security, information infrastructure, resource management, data management, communication, fault detection, and portability. It is packaged as a set of components that can be used either independently or together to develop applications. Every organization has unique modes of operation, and collaboration between multiple organizations is hindered by incompatibility of resources such as data archives, computers, and networks. The Globus Toolkit was conceived to remove obstacles that prevent seamless collaboration. Its core services, interfaces and protocols allow users to access remote resources as if they were located within their own machine room while simultaneously preserving local control over who can use resources and when.
The Globus Toolkit has grown through an open-source strategy similar to the Linux operating systems, and distinct from proprietary attempts at resource-sharing software. This encourages broader, more rapid adoption and leads to greater technical innovation, as the open-source community provides continual enhancements to the product.
Enhancements:
- This release adds a new reliable file transfer client. It has been upgraded to SpiderMonkey version 1.60, GPT 3.9, and OpenSSH 4.5p1 with the high performance patch, and ported to Mac OS X / Intel x86.
- Test coverage, credentials handling in the security module, and handling of XML schema have been improved.
- An authorization portal framework has been introduced.
