Dusty deck

Automatic parallelizing compilers have been a goal of some computer science researchers for many years (see, e.g., Refs. 51-56). Many others regard this as an impossible ambition, and the assertion by some vendors that dusty deck sequential FORTRAN codes may run efficiently on their MPP though the magic of their compiler should be regarded with skepticism. 

Software Eor collaborations, there will be increasing needs for user-friendly and robust software that provides assured standards for quality, reliability, access, interoperabihty, and sustained maintenance. Standards are needed to facihtate collaborative interactions between applications personnel who are not experts in computer science. Use of software to upgrade legacy codes (or dusty decks)—codes that have been around a while (10-15 years), usually written by others who are no longer available, run on current-generation computers and systems for which it was not optimized, and therefore difficult to modify and de-... 

Dusty air is pulled from inside the deck shroud through a flexible duct to primary and secondary filter media. The primary filter or dust separator often includes a self-cleaning back-pulse feature that dumps the collected particles to the ground. Secondary release of particles to the air is minimized by a dump shroud. The dust collection system works best when good design and maintenance practices are implemented by skilled and properly trained operators ... 

For towers of 10 ft or more in diameter, check for out-of-levelness of a tray check using a carpenter s laser level, available in hardware stores for about 40. Purchase a level that has short tripod legs. Use the bubble to level up the legs. Set the level on one end of the tower, and check the height of the red beam at the other end and at the center of the tray for out-of-levelness. As it is often dim and dusty in the tower, the trace of the red laser may be clearly visible. Low points and areas of the tray deck that are out of level can now be easily identified.
