Because of the relative slowness of main memory (compared with the CPU), most computers have a much smaller, but much faster cache memory subsystem that augments main memory. The size of the cache memory and the extent to which a program can utilize the cache can be critical deterrninants of performance. Again, there are some common optimization techniques designed to maximize cache utilization. 

Loops that could not be vectorized on conventional vector computers often performed very well under the Multiflow architecture and, unlike vector machines, for which a person could spend a great deal of time optimizing programs, substantially less could be done on the Multiflow, as most of the work fell to the compiler anyway. All the usual optimizations for memory utilization and cache usage also appHed to the Microflow. There were, of course, programs for which the compiler could not make good use of the multiple functional units, and the computer would mn at the speed of just one or two iadividually quite slow functional units.

Sodium metal is produced commercially on the kilotonne scale by the electrolysis of a fused eutectic mixture of 40% NaCl, 60% CaCh at 580°C in a Downs cell (introduced by du Pont, Niagara Falls, 1921). Metallic Na and Ca are liberated at the cylindrical steel cathode and rise through a cooled collecting pipe which allows the calcium to solidify and fall back into the melt. Chlorine liberated at the central graphite anode is collected in a nickel dome and subsequently purified. Potassium cannot be produced in this way because it is too soluble in the molten chloride to float on top of the cell for collection and because it vaporizes readily...
