Using communication-to-computation ratio in parallel program design and performance prediction (2024)

FAQs

What is the communication to computation ratio? ›

The C/C ratio for a specific execution of an application on a specific machine is the execution's communication cost divided by computation cost. The use of C/C ratio suggests performance models based on utilization of the communication medium.

Communication to Computation Ratio (CCR) is a crucial metric in distributed optimization, balancing information exchange (communication) and gradient calculations (computation) at each iteration for algorithm efficiency and customization.

Simply Put, 2:1 Is Key. If we expand Epictetus's aphorism into a suggestion for how to more effectively communicate, we get something like the following: When it comes to communication, you should work hard to receive twice as much as you transmit.

2 Choose communication metrics

For example, some common quantitative metrics are reach, frequency, engagement, feedback, and conversion. These metrics can be measured using tools such as surveys, polls, analytics, and reports.

An effective communication is directly proportional to an effective negotiation. The better the communication is the better the negotiation would be. Discussion does not mean fighting and shouting, instead it is simply the exchange of one's ideas, thoughts and opinions with each other.

A typical study points out that many of us spend 70 to 80 percent of our time in some form of communication. Of that time, we spend about 9 percent writing, 16 percent reading, 30 percent speak- ing, and 45 percent listening.
