I think I am correct in saying that scheduling is the/a main principle of the single core CPU, where the CPU is interrupted when switching from processing one set of instructions belonging to one program to another set of instructions.
Phoronix: StarPU Tries To Make Hybrid CPU/GPU Programming Easy
StarPU is described as a unified run-time system for heterogeneous multi-core architectures that is a task programming library with support for CPUs and GPUs. StarPU tries to be more effective than OpenMP, OpenACC, and the many other multi-threaded/multi-device programming interfaces...
I have a dual-core Core i3 on my laptop, and System Monitor gives usage statistics for 4 different "CPUs". I'm assuming that the 4 CPUs the OS recognizes are actually the cores in the processor, and the 4 "CPUs" are due to the hyperthreading, which I understand creates a virtual core for every physical core.
I am looking for a way to detect if one of the cpus on a multi-cpu linux server is maxed out for over an hour. How can I detect this using standard unix utilities/open source tools?
Context as to why I need this: We are running an ETL tool on top of the system that has an issue we are trying to figure out where it maxes out a single core. When it does this, the program stops working.
I am sorry if this is a duplicated question, but I didn't found any answer to my question.
So I already have read something about multi-thread/multi-core on Android at google, saying that actually the Android just use one core when launching a specific application, that makes me thinking about it.
So if I use threads on my application Android will not use the other cores to execute the thread?
To process and analyze all the data generated on a multi-core embedded device, a safe and efficient database management system is necessary. ITTIA DB SQL addresses the challenge of increasing data volume on multi-core systems.
