Computational Tune-Up

As part of a general effort to improve performance, a variety of key computational routines and algorithms have been scrutinized and tuned for optimal performance. The result is that most statistical computations in EViews are now significantly faster. You should definitely notice the difference in formerly long-running routines, most notably in iterative or complicated procedures.

Multi-processor Support

EViews 7 has been retooled to take advantage of multiple-processor cores. And you don't have to do a thing to enable multi-core support. By default, EViews 7 will automatically sense whether your computer sports more than one processor core and will optimize its calculations accordingly (using all of the cores).

If you wish, you may override this setting for up to eight threads. This allows you to increase the number of threads EViews uses to beyond the physical number of cores. We have not found this to be effective, but, in principle, it could improve performance with hyper-threading. If you require more processing power for other applications, you may wish to limit the number of threads EViews uses by setting this number below the physical number of cores. This is guaranteed to work with Intel processors, and, to our knowledge, should work with other brands of processors as well.

To take advantage of the user-specified settings, go to the Options/General Options dialog in the main EViews menu. The Multi-processor/Multi-core use section may be used to define the maximum number of threads you would like to allow EViews to use when processing statistical calculations. EViews treats processors and cores symmetrically, and does not include hyper-threaded processors. In general, we recommend leaving this setting at Auto. You may click on the Reset to EViews Defaults button to return to the default settings.
