You run a 16-bit scientific data analysis package on your Windows 2000 Professional computer. Thepackage consists of three components.The first component is a data acquisition application that monitors continuous data output fromscientific instruments. The second component is a data analysis application that receives data from thedata acquisition application by using shared memory. The third component is a data graphingapplication that displays the processed data in real time.The data analysis application communicates with the data graphing application by using OLE. When youattempt to analyze large data sets, your computer is not able to display data in real time. You install asecond processor in your computer. Only one processor is used while the package is running, even thoughtask manager shows both processors.You want your data analysis package to use both processors.
