New programs adopt producer and consumer models. The producer speed is very fast, data is almost in the memory, and processing is very fast. Consumers need frequent I/O. Therefore, we plan to allocate different cores to producers and consumers. The producer only needs one core, and the rest is allocated to the consumer. I checked this information and the shell side has the taskset command available. Taskset: -P: The pid of the running process -The spe

Multiple multi-core CPUs are now the mainstream servers. Many applications, such as Squid and nginx, have the ability to distribute processes or threads to different CPU cores. How can we view the distribution of different processes in the CPU core. Use the top tool and use the pgrep or pidof commands. For example, to view the distribution of

The quad-core is a processor core that has four functions on one processor based on a single semiconductor. In other words, four of the physical processor cores are integrated into one core. The difference between the quad core and the dual core is that on multitasking, the CPU of the four cores open four programs to open four programs faster than the dual

There are several different processor information that you can obtain: Number of physical processors, number of cores, and number of logical processors, which can be different. Two dual-core hyper-threading (Enabled) processors are available on two physical processors, four cores, and eight logical processors. The number of logical processors isEnvironmentClass, but other information can only be obtained th

Uncle also said that parallel and serial performance is improved by N times (N is determined by the number of operating systems and the number of cpu cores), and the performance is improved by n Returned directory Parallelism is. net4.5 focuses on the technology and is encapsulated into System. threading. in the Tasks namespace, the static class Parallel is provided for external users.
