Comet Webinar: Obtaining Hardware Information and Monitoring Performance
Thursday, September 19, 2019
6:00 PM - 7:00 PM UTC
This event will be held remotely.
In this webinar we start by describing how to obtain hardware and system information such as CPU specifications, memory quantity, cache configuration, mounted file systems and their usage, peripheral storage devices and GPU properties. This information is useful for anyone who is interested in how hardware specs influence performance or who needs to report benchmarking data. We then cover the use of top for monitoring systems usage and gprof for basic code profiling. We conclude with a description of the memory hierarchy (registers, cache, memory, external storage) and show how an understanding of cache can be used to write more efficient code.
