Simple Example
|
||
|
|
---------------
|
||
|
|
|
||
|
|
To get CPU count::
|
||
|
|
>>> from plyer import cpu
|
||
|
|
>>> # 1 socket, 1 core per socket, 2 threads per core
|
||
|
|
>>> cpu.sockets # 1 CPU socket (or slot)
|
||
|
|
1
|
||
|
|
>>> cpu.physical # 1 CPU socket * 1 core per socket
|
||
|
|
1
|
||
|
|
>>> cpu.logical # 1 CPU socket * 1 core per socket * 2 threads per core
|
||
|
|
2
