The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.
If you know of an easy to use, open source, search engine ... please contact support@midrange.com.

Don't have one Vern. Sorry. Turns out it apparently isn't an option
available in my situation. However, if it were, I should think it would
be beneficial for any thread-safe application. My impression is that it
allows the caching retrieval mechanism to load the instruction streams
more efficiently, thereby increasing throughput. The improvement in any
case appears to be on the order of 25-35%, not x * number of processors,
since at the end of the day, a single processor can only execute a
single instruction at a time.

what it SMT is about.
