TAU (Tuning and Analysis Utilities) is a set of tools for analyzing the performance of C, C++, Fortran and Java programs. It collects much more information than is available through prof or gprof, the standard Unix utilities, including per-process, per-thread, and per-host information, inclusive and exclusive function times, profiling groups that allow you to organize data collection, access to hardware counters on some systems, per-class and per-instance information, the ability to separate data for each template instantiation, start/stop timers for profiling arbitrary sections of code, and support for collection of statistics on user-defined events.
Release Notes: This release adds a port to ARM Linux, Intel MIC platforms, CUDA 5.0 support, UPC Runtime instrumentation for Cray CCE and BUPC, improvements in the MPI wrapper, support to ParaProf 3D for IBM BG/Q, and ARM Linux.
The Web10G project (a follow-on from Web100) was created to produce a complete host-software environment that will run common TCP applications at 100% of the available bandwidth, regardless of the magnitude of a network's capability. Web10G has endowed TCP with better instrumentation. This instrumentation is the foundation for both the TCP autotuning performed in process-level code and the process-level tools designed to locate bottlenecks within the following major subsystems: the sending application, the sending OS, the Internet path, the receiving OS, and the receiving application. Measurement tools have also been built on this instrumentation to display performance indicators to end-users, as well as provide internal diagnostics for network and system administrators.
Release Notes: User access to kernel data is now through the netlinks interface.
The THREDDS (Thematic Realtime Environmental Distributed Data Services) project is developing middleware to bridge the gap between data providers and data users. The goal is to simplify the discovery and use of scientific data and to allow scientific publications and educational materials to reference scientific data. The mission of THREDDS is for students, educators and researchers to publish, contribute, find, and interact with data relating to the Earth system in a convenient, effective, and integrated fashion. Just as the World Wide Web and digital library technologies have simplified the process of publishing and accessing multimedia documents, THREDDS is building infrastructure needed for publishing and accessing scientific data in a similarly convenient fashion.
Release Notes: This release adds numerous bugfixes.
The Program Database Toolkit (PDT) is a powerful tool infrastructure that provides access to the high-level interface of source code for analysis tools and applications.
Release Notes: This release adds support for the ARM Linux platform, the ROSE parser for C, C++, and UPC, the MAQAO binary rewriter, and the TAU source instrumentor.
SuiteSparse is a suite of C, Fortran, and MATLAB functions for manipulating sparse matrices.
Release Notes: This release adds GPU support for CHOLMOD and adds assorted bugfixes.
SAOImage DS9 is an astronomical imaging and data visualization application. DS9 supports FITS images and binary tables, multiple frame buffers, region manipulation, and many scale algorithms and colormaps. It provides for easy communication with external analysis tasks and is highly configurable and extensible. DS9 is a stand-alone application that requires no installation or support files. It supports advanced features such as multiple frame buffers, mosaic images, tiling, blinking, geometric markers, colormap manipulation, scaling, arbitrary zoom, rotation, pan, and a variety of coordinate systems.
Release Notes: This release adds true 3D data visualization, color tags, and cropping. Regions now support analysis tasks unique to each region type. TIFF, JPEG, and PNG files can be loaded and exported directly. The GUI has been rebuilt. New WCS support for non-FITS WCS projections has been added to DS9: TNX, ZPX, SCAMP, SIP, and HEALPIX. Enhancements and improvements have been made in the support for the following FITS WCS projections: COD, COO, COE, COP, ZEA, and CAR.
The goal of Cheix USB is a Linux image executing from a USB storage device into a running OS, either Linux or Windows, so that the host machine does not have to support booting from the USB device. The root filesystem and boot partitions are read-only to preserve the USB device. All writes are done in a tmpfs. The only writes to the USB storage device are those explicitly made by the user. Cheix's ISO can currently be used to create either a bootable USB or a hard-drive installation.
Release Notes: This release adds minor fixes and improvements to the cheix_admin script, admin.html, and the INSTALL file. These are all documentation changes.
SpatiaLite is a library for geographic information systems (GIS) that implements the core OpenGIS specification. It provides SQLite with basic support for spatial data is intended for lightweight GIS projects.
Release Notes: This release adds assorted enhancements and bugfixes.
ScalaBLAST is a high-performance multiprocessor implementation of the NCBI BLAST library. It supports all 5 primary program types (blastn, blastp, tblastn, tblastx, and blastx) and several output formats (pairwise, tabular, and XML). It will run on most multiprocessor systems which have MPI installed, and can run over a wide variety of interconnects, including infiniband, quadrics, and ethernet. It is designed to run a large number of queries against either large or small databases. It parallelizes the BLAST calculations by dynamically scheduling them across processors using a fault-resilient scheme.
Release Notes: This is a bugfix release.
Scalasca is a toolset that can be used to analyze the performance behavior of parallel applications and to identify opportunities for optimization. It supports an incremental performance-analysis procedure that integrates runtime summaries with in-depth studies of concurrent behavior via event tracing, adopting a strategy of successively refined measurement configurations.
Release Notes: This is a bugfix release.
