What is $$Network RAM$$ in the NOW project? How does it provide a performance benefit for serial as well as parallel programs? A$.)$ Network RAM attaches a memory address of a message handler to the beginning of a network packet, reducing latency and processing overhead for communication. B$.)$ Network RAM allows you to page to nearby workstations instead of your local disk. Because the network is faster than disks, this helps any program that needs lots of memory. C$.)$ Network RAM allows applications to map binary files into different address spaces from the same network node, reducing memory usage for serial and parallel programs.
