Free cluster software for mac

Enhancements:

• General Fine Tuning
• Made Downloads Page

Requirements: Mac OS X 10.5 or later.

iDXCluster is an easy to use DX Cluster program geared towards SW listeners, DXers, utility monitors, and others. It doesnt require a packet radio link, telnet, or any complicated software or setup, only an internet connection is required.

A DX Cluster is a way for DXers to share tips on what stations they are currently hearing. Stale DX news is useless, so a DX Cluster allows people to share their loggings within seconds.

Just download the program, enter in your Name and location, and thats it. Loggings from other listeners will be displayed on the cluster screen in real-time.

You can submit your own loggings as well of course. You can also filter the types of loggings you want to see, so you dont have to see stations that you have no interest in.Clicking on a logging line will bring up a window with some more detailed logging information, and eliminates the need to horizontally scroll to see the comments/etc on the right side.

RadioDXCluster is simple, configurable terminal software used to control your TNC (Terminal Node Controller) to connect with your local AR-DX Cluster using your radio.

This program combines features contained in MacTNC, a TNC control program, and NetDXCluster (formerly MacDXCluster), similar software that accesses DX Clusters via the Internet rather than a radio link.

Celestia is a free real-time space simulation that lets you experience our universe in three dimensions. Unlike most planetarium software, Celestia doesnt confine you to the surface of the Earth.
You can travel throughout the solar system, to any of over 100,000 stars, or even beyond the galaxy.
All travel in Celestia is seamless; the exponential zoom feature lets you explore space across a huge range of scales, from galaxy clusters down to spacecraft only a few meters across.
A point-and-goto interface makes it simple to navigate through the universe to the object you want to visit.

Commander is an enhanced version of the original Commander which is now fully free!
The tool executes UNIX shell commands standalone with each new open window working in its own pipe and eventually with windows added to share a same pipe. Additionally it offers some basic yet flexible features, easy to use and set, which make possible to achieve by simply point and click, batch of commands and harnessing their power without resorting to or knowing shell scripting.
Main features:
- Multiple windows for running shell commands and keeping their result at hand
- Windows bound to pipes or sharing them can be indifferently mixed and used
- Possibility did chain in sequence multiple command windows for batch execution
- multiple way to control chained sequence
- Possibility to achieve pseudo-interactivity in some cases
- Possibility to detach window from its command in case of blocking conditions
- Aids for finding any pending processes holding a pipe after the detach
- Searchable result
- Possibility to save and reuse most frequent or complex formatted commands and parameters
- Possibility to print results
- Access to a dictionary of common or custom commands
- Possibility to edit and customize the dictionary included in the bundle
- Possibility to filter the dictionary for fast finding and access
- Possibility to drag & drop text from the dictionary to the command fields.
Enhancements:
- Commander contains both visual and functional improvements for enhancing the user experience without changing its basic interface and use.
- Newly open windows by default allocate a private pipe for communicating with the underneath command being executed; by selecting the new "New Alias" menu item, a new window will open without allocating a new pipe but sharing the same one from the window parent.
- By reusing a same window or by entering commands in a cluster of windows identified by the same pipe number commands will run and re-use the same context.
- A new field in the command window makes possible under certain conditions to handle some extent of interactivity in commands.
- In case of dead-locks, as commands not responding or any other condition where windows do not get replied, it is possible to detach them from their process.
- If some process after the detach is still holding a pipe this can be detected visually and eventually more details displayed.
- Some internal bugs are cleared.

SkyChart is an advanced planetarium program that accurately simulates and displays the sky as it appears in the present, or from thousands of years in the past or future. With SkyChart you can view the sky from any place on Earth, from any object in the solar system, or even from thousands of light years beyond it.
SkyChart is also a telescope control program, supporting all of the leading computer-controlled telescopes available on the market today. SkyChart lets you enjoy the benefits of computer-aided observing: see where the telescope is pointing on your computer screen, or slew the telescope to any object in the sky with a single click of the mouse.
Note: SkyChart Updater is only available for registered users.
Main features:
- Accurately reproduces eclipses, transits, and occultations - as seen not only from Earth, but also from any place in the solar system. Watch the Moon orbit the Earth as seen from another planet, or witness the passage of a comet through the solar system as if you were riding on the comet!
- Shows you the sky from beyond the solar system, and lets you watch the celestial scenery change as you move. View the constellations from hundreds or thousands of light years away!
- Animates the sky forward or backward in time over thousands of years. Watch the celestial poles precess; see the constellations shift as the stars move over the millenia.
- Supports leading computer-controlled telescopes from Meade, Celestron, and other manufacturers. See where the telescope is pointing on your computer screen; slew the telescope to any object in the sky with a single click of the mouse. SkyChart III even has a "red screen" mode to preserve your night vision when working at the telescope!
- Includes two fully-customizable object databases. The Standard database is installed on your hard drive and contains 400,000 stars, plus tens of thousands of star clusters, nebulae, and galaxies. The Large database resides on the CD-ROM, and contains everything in the Standard database, plus over 19 million additional stars, and 1 million more galaxies. Import your own database files to add new comets, asteroids, stars, planets, or deep-sky objects. Any existing object in the database can be edited, even the constellations!
- Renders star images and planet surfaces in 32-bit color with data derived from NASA spacecraft imagery. Print high-resolution finder charts in black and white or color; or export images in many different file formats like BMP, GIF, JPEG, PICT, TIFF. Save animations as GIF files viewable in any web browser!
- Computes positions of the Sun, Moon, major planets, their moons, dozens of comets and asteroids to within milli-arcseconds of their values in the Astronomical Almanac. Investigate historical events like eclipses and conjunctions that happened centuries ago, and accurately reproduce what ancient peoples saw.
- Computes and displays the positions of Earth satellites from standard NASA/NORAD two-line element satellite orbit files using the full-precision SGP4/SDP4 satellite orbit models. Follow the International Space Station across the sky, or predict a satellite passage in front of the Moon.
Enhancements:
- This release brings the code base of the English-language version up to sync with the newly released Spanish-language version. A number of changes were made to support better internationalization/localization:
- The decimal-point character is now locale-specific; decimals are displayed as "," in European locales, and "." in North America. (The computers regional settings are used to determine the locale.) Decimal points in text import files and settings files are always assumed to be the US (".") decimal-point character, for consistency. [Note: this functionality is only present in the Windows version of SkyChart III; were still trying to make it work on Mac OS X.]
- All strings in data files, and settings descriptions in settings files, are converted to Windows Latin-1 encoding before being written to disk. This ensures that accented and other european-language characters will translate properly between Mac and Windows.
- A case-sensitive search for an object name is now sensitive to both case and diacritics (e.g. accents, umlauts, etc). When case is ignored, diacritics are also ignored - e.g. a search for "Jupiter" will also find "Jpiter", and a search for "Saturn" will also find "Sturn".
- In the chart legend, the full names of deep sky objects are being displayed, instead of abbreviations.
- In the "Object Info" window, a number of text strings and buttons were rearranged. The object type for the Sun is now displayed as "Star"; for the major planets as "Planet"; for moons as "Moon". The star type for single stars is now simply listed as "Star".
- For years outside 1600 - 2100 A.D., the program uses new expressions for the precession of the equinox provided by W. M. Owen of JPL. These new expressions should provide realistic results for a much wider interval of +/- 500,000 years from J2000. (The previous expressions "blew up" and displayed highly unrealistic results after roughly 10,000 years from J2000.) For the time period 1600 - 2100 A.D., the previous (IAU 1976) expressions for precession are still used.
- Previous versions of the Windows installer for SkyChart III installed a 16-bit version of the uninstall application (UnWise.exe). This update replaces it with the 32-bit version.
- Fixed a crash in the Mac OS X version that occurred when moving the mouse inside a progress-bar dialog.
- Removed timing code in the Mac OS X version that was causing a performance-profiling dialog to appear sporadically.
- The Mac OS X version of SkyChart III can now launch properly on Macs with 2.0 GB of RAM or more installed. The Mac OS X installer/updater application should no longer display a warning on Macs with more than 2.0 GB of RAM. (This warning can safely be ignored, however.)
- The Mac OS X version now has the main windows "close" button enabled; clicking it quites the application. The "Quit" menu command has moved from the File menu to the "SkyChart III" menu, for better conformance with Apples Mac OS X interface guidelines.

The CUDA Toolkit is a C language development environment for CUDA-enabled GPUs.
In a matter of a few years, the programmable graphics processor unit has
developed into an absolute computing workhorse. With multiple cores driven by very high memory bandwidth, todays GPUs offer incredible resources for both graphics and non-graphics processing.
The main reason behind such an evolution is that the GPU is specialized for compute-intensive, highly parallel computation exactly what graphics rendering is about and therefore is designed such that more transistors are devoted to data processing rather than data caching and flow control.
The CUDA development environment includes:
- nvcc C compiler
- CUDA FFT and BLAS libraries for the GPU
- Profiler
- gdb debugger for the GPU (alpha available in March, 2008)
- CUDA runtime driver (now also available in the standard NVIDIA GPU driver)
- CUDA programming manual
The CUDA Developer SDK provides examples with source code to help you get started with CUDA. Examples include:
- Parallel bitonic sort
- Matrix multiplication
- Matrix transpose
- Performance profiling using timers
- Parallel prefix sum (scan) of large arrays
- Image convolution
- 1D DWT using Haar wavelet
- OpenGL and Direct3D graphics interoperation examples
- CUDA BLAS and FFT library usage examples
- CPU-GPU C- and C++-code integration
- Binomial Option Pricing
- Black-Scholes Option Pricing
- Monte-Carlo Option Pricing
- Parallel Mersenne Twister (random number generation)
- Parallel Histogram
- Image Denoising
- Sobel Edge Detection Filter
- MathWorks MATLAB Plug-in

Main features:
- Standard C programming language enabled on a GPU.
- Unified hardware and software solution for parallel computing on CUDA-enabled NVIDIA GPUs.
- CUDA compatible GPUs range from lower power notebook GPUs to high performance, multi-GPU systems.
- CUDA-enabled GPUs support the Parallel Data Cache and Thread Execution Manager.
- Standard numerical libraries for FFT (Fast Fourier Transform) and BLAS (Basic Linear Algebra Subroutines).
- Dedicated CUDA driver for computing.
- Optimized direct upload and download path from the CPU to CUDA-enabled GPU.
- CUDA driver interoperates with OpenGL and DirectX graphics drivers.
- Support for Linux 32/64-bit and Windows XP 32/64-bit operating systems.
- Direct driver and assembly level access through CUDA for research and language development.

Enhancements
- Visual Profiler for the GPU - The most common step in tuning application performance is profiling the application and then modifying the code. The CUDA Visual Profiler is a graphical tool that enables the profiling of C applications running on the GPU. This latest release of the CUDA Visual Profiler includes metrics for memory transactions, giving developers visibility into one of the most important areas they can tune to get better performance.
- Improved OpenGL Interop - Delivers improved performance for Medical Imaging and other OpenGL applications running on Quadro GPUs when computing with CUDA and rendering OpenGL graphics functions are performed on different GPUs.
- Texture from Pitch Linear Memory - Delivers up to 2x bandwidth savings for video processing applications.
- Zero-copy - Enables streaming media, video transcoding, image processing and signal processing applications to realize significant performance improvements by allowing CUDA functions to read and write directly from pinned system memory. This reduces the frequency and amount of data copied back and forth between GPU and CPU memory. Supported on MCP7x and GT200 and later GPUs.
- Pinned Shared Sysmem - Enables applications that use multiple GPUs to achieve better performance and use less total system memory by allowing multiple GPUs to access the same data in system memory. Typical multi-GPU systems include Tesla servers, Tesla Personal Supercomputers, workstations using QuadroPlex deskside units and consumer systems with multiple GPUs.
- Asynchronous memcopy on Vista - Allows applications to realize significant performance improvements by copying memory asynchronously. This feature was already available on other supported platforms but is now available on Vista.
- Hardware Debugger for the GPU - Developers can now use a hardware level debugger on CUDA-enabled GPUs that offers the simplicity of the popular open-source GDB debugger yet enables a developer to easily debug a program that is running 1000s of threads on the GPU. This CUDA GDB debugger for Linux has all the features required to debug directly on the GPU, including the ability to set breakpoints, watch variables, inspect state, etc.
- Exclusive Device Mode - This system configuration option allows an application to get exclusive use of a GPU, guaranteeing that 100% of the processing power and memory of the GPU will be dedicated to that application. Multiple applications can still be run concurrently on the system, but only one application can make use of each GPU at a time. This configuration is particularly useful on Tesla cluster systems where large applications may require dedicated use of one or more GPUs on each node of a Linux cluster.
Pinned Memory Support:
- These new memory management functions (cuMemHostAlloc() and cudaHostAlloc()) enable pinned memory to be made "portable" (available to all CUDA contexts), "mapped" (mapped into the CUDA address space), and/or "write combined" (not cached and faster for the GPU to access).
- cuMemHostAlloc
- cuMemHostGetDevicePointer
- cudaHostAlloc
- cudaHostGetDevicePointer
Function attribute query:
- This function allows applications to query various function properties.
- cuFuncGetAttribute
2D Texture reads from pitch linear memory:
- You can bind linear memory that you get from cuMemAlloc() or cudaMalloc() directly to a 2D texture. In previous releases, you were only able to bind cuArrayCreate() or cudaMallocArray() arrays to 2D textures.
- cuTexRefSetAddress2D
- cudaBindTexture2D
Flags for event creation:
- Applications can now create events that use blocking synchronization.
- cudaEventCreateWithFlags
New device management and context creation flags:
- The function cudaSetDeviceFlags() allows the application to specify attributes such as mapping host memory and support for blocking synchronization.
- cudaSetDeviceFlags
Improved runtime device management:
- The runtime now defaults to attempting context creation on other devices in the system before returning any failure messages. The new call cudaSetValidDevices() allows the application to specify a list of acceptable devices for use.
- cudaSetValidDevices
Driver/runtime version query functions:
- Applications can now directly query version information about the underlying driver/runtime.
- cuDriverGetVersion
- cudaDriverGetVersion
- cudaRuntimeGetVersion
New device attribute queries:
- CU_DEVICE_ATTRIBUTE_INTEGRATED
- CU_DEVICE_ATTRIBUTE_CAN_MAP_HOST_MEMORY
- CU_DEVICE_ATTRIBUTE_COMPUTE_MODE
Documentation:
- Doxygen-generated and cross-referenced html, pdf, and man pages.
- Runtime API
- Driver API
