In the past, that might have meant a release relatively light on new features, much as AutoCAD 2009 offered few surprises beyond the now-familiar ribbon interface. But while really big enhancements may have to wait until next year, AutoCAD 2012 provides a wealth of welcome changes.
Borrowing from the MacLast fall, Autodesk quelled rumors when it released the first native Macintosh version of AutoCAD in nearly 20 years (see deskeng.com/articles/aabamx.htm). In addition to a totally Mac interface, AutoCAD 2011 for the Mac featured new in-canvas viewport controls. These same tools have now been added to AutoCAD 2012, enabling users to change viewport settings, views and visual styles by using tools that always appear in the upper-left corner of each viewport.

In-canvas control is further exploited in AutoCAD 2012 by the addition of new user coordinate system (UCS) icon functions. The UCS icon can now be selected and manipulated by using grips to quickly align the UCS with existing objects, including curved surfaces and solids. You can also right-click on the UCS icon to access additional UCS controls from a new shortcut menu, making it much easier to manipulate the coordinate system particularly when working in three-dimensional space.
Creating Associative ArraysOne particular addition to AutoCAD 2012 stands out as one of the biggest productivity improvement in years: AutoCAD can now create associative arrays.
AutoCAD 2012 also includes the ability to import 3D models in a wide variety of formats, including CATIA, NX, Parasolid, Creo Elements/Pro, Rhino and SolidWorks. Depending on the size and complexity of the model, this can take quite some time. An Import icon displays on the status bar tray, and a notification bubble appears once the import is complete so that you can place the 3D model into your AutoCAD drawing.
AutoCAD 2012 introduces a totally new set of tools for documenting 3D models. If a drawing file contains a 3D model, users can switch to paper space and quickly create a base 2D drawing view of the 3D model. Once a base view has been placed, you can then create projected orthogonal and isometric views and adjust the scale and appearance of those views. And if you make any changes to the original 3D model, AutoCAD displays a balloon notification: Clicking a link immediately updates the drawing views to reflect those changes.
AutoCAD 2012 includes a layer enhancement that lets you freeze specified layers in all viewports except the current viewport, improvements to multi-leaders, and the inclusion of a Delete Duplicate command as a core function rather than relying on an Express Tool. Other enhancements include:
With each new release of its flagship, Autodesk also adds new features to AutoCAD LT, the lower-cost 2D alternative to AutoCAD. Once again, AutoCAD LT 2012 benefits from new features in AutoCAD 2012 and also gains some functionality once reserved exclusively to AutoCAD.
Perhaps the biggest function to finally migrate from AutoCAD to AutoCAD LT is the Sheet Set Manager. AutoCAD users have long been able to create sheet sets to help organize sets of drawings, create layout views, and reduce the steps needed to publish documents. That capability has finally made its way into AutoCAD LT 2012, making it a more equal partner in the development of 2D documentation.
AutoCAD LT 2012 now includes the Sheet Set Manager, formerly only available in AutoCAD itself. The new release of LT also includesthe same auto-complete functionality, an Autodesk Exchange portal, and the Content Explorer plug-in.
Las implementaciones en MPI consisten en un conjunto de bibliotecas de rutinas que pueden ser utilizadas en programas escritos en los lenguajes de programación C, C++, Fortran y Ada. La ventaja de MPI sobre otras bibliotecas de paso de mensajes, es que los programas que utilizan la biblioteca son portables y rápidos. Existen múltiples implementaciones de MPI.
MPICH es una implementación de MPI libre y portable. MPICH es software libre y gratuito. Está disponible para la mayoría de distribuciones de Linux y también para MAC OS X y Microsoft Windows. 2ff7e9595c
