Matlab multi-core CPU parallelism and multi-threading

Introduction The concepts that need to be understood here are: the differences between multi-core, multi-process, multi-thread, parallel computing, and concurrent computing. What is multi-core In the early days of computer design, single-processor systems evolved into multi-processor systems in response to the need for more computing performance. A more modern, similar system design trend is to […]

Linux performance analysis (7) CPU performance (2) How to understand the average load

1. How to understand load average ① How to check the average complexity Commands to view ‘system load’: top, ‘uptime’, w, ‘cat /proc/loadavg’, tload /proc/loadavg Thinking: What is the ‘meaning’ of uptime’s output in each column? Key points: ‘Current time’, ‘System running time’, ‘Number of logged in users’, ‘Average load’ ② Thinking: How to ‘observe’ […]
