"Derivative Works" shall mean any work, whether in Source or Object
|
||||
form, that is based on (or derived from) the Work and for which the
|
||||
editorial revisions, annotations, elaborations, or other modifications
|
||||
represent, as a whole, an original work of authorship. For the purposes
|
||||
of this License, Derivative Works shall not include works that remain

|
||||

|
||||
by such Contributor that are necessarily infringed by their
|
||||
Contribution(s) alone or by combination of their Contribution(s)
|
||||
with the Work to which such Contribution(s) was submitted. If You
|
||||
institute patent litigation against any entity (including a
|
||||
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
||||

|

granted to You under this License for that Work shall terminate
|

stating that You changed the files; and

||||
|
||||
(c) You must retain, in the Source form of any Derivative Works
|
||||
that You distribute, all copyright, patent, trademark, and
|
||||
attribution notices from the Source form of the Work,
|
||||
excluding those notices that do not pertain to any part of
|
||||
the Derivative Works; and
|
||||
|

||||
pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed
|
||||
as part of the Derivative Works; within the Source form or
|
||||

|
||||
within a display generated by the Derivative Works, if and
|
||||
wherever such third-party notices normally appear. The contents
|
||||
of the NOTICE file are for informational purposes only and
|
||||
do not modify the License. You may add Your own attribution
|
||||
notices within Derivative Works that You distribute, alongside
|

|
||||

||||
|
||||
You may add Your own copyright statement to Your modifications and
|
||||
may provide additional or different license terms and conditions
|
||||

|
||||
the conditions stated in this License.
|
||||
|
||||

|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of
|
||||
this License, without any additional terms or conditions.

the terms of any separate license agreement you may have executed
|
||||
with Licensor regarding such Contributions.

||||
|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||
names, trademarks, service marks, or product names of the Licensor,

Count the number of CPUs on the current machine.
|
||||
|
||||
## Usage
|
||||
|
||||
Add to Cargo.toml:
|
||||
|
||||
```toml
|
||||
[dependencies]
|
||||
num_cpus = "1.0"
|
||||
```
|
||||
|
||||
In your `main.rs` or `lib.rs`:
|
||||
|
||||
```rust
|
||||
extern crate num_cpus;
|
||||
|
||||
// count logical cores this process could try to use
|
||||
let num = num_cpus::get();
|

//! A crate with utilities to determine the number of CPUs available on the
|
||||
//! current system.
|
||||
//!
|
||||
//! Sometimes the CPU will exaggerate the number of CPUs it contains, because it can use
|
||||
//! [processor tricks] to deliver increased performance when there are more threads. This
|
||||
//! crate provides methods to get both the logical and physical numbers of cores.
|
||||
//!
|
||||
//! This information can be used as a guide to how many tasks can be run in parallel.
|
||||
//! There are many properties of the system architecture that will affect parallelism,
|
||||
//! for example memory access speeds (for all the caches and RAM) and the physical
|
||||
//! architecture of the processor, so the number of CPUs should be used as a rough guide
|
||||
//! only.
|
||||
//!
|
||||
//!
|
||||
//! ## Examples
|
||||
//!
|
||||
//! Fetch the number of logical CPUs.
|
||||
//!
|
||||
//! ```
|
||||
//! let cpus = num_cpus::get();
|
||||
//! ```
|
||||
//!
|
||||
//! See [`rayon::Threadpool`] for an example of where the number of CPUs could be
|
||||
//! used when setting up parallel jobs (Where the threadpool example uses a fixed
|
||||
//! number 8, it could use the number of CPUs).
