# BlasNet
BlasNet is an optimized library for basic linear algebra operations on arrays written in C\# and developed at [Proxem](https://proxem.com).

## Requirements
BlasNet is developed in .Net Standard 2.0 and is compatible with both .Net Framework and .Net Core thus working on Windows and Linux platform.
For Mac OS users there shouldn't be any problem but we didn't test extensively.
### Intel MKL
Intel's math kernel library is used as a backend to optimize arrays operations when available.
In order to use MKL you must launch the provider in your code. This step depends of your operating system :
#### Windows Users
You first need to download [Intel's MKL](https://software.intel.com/en-us/mkl/choose-download/windows) libraries for Windows. Check that the folder contains `mkl_rt.dll` which is the main library used by BlasNet.
To set the provider to use `mkl_rt.dll` for the low level array operations place the following line at the beginning of your code :
```
using BlasNet;
public namespace Test
{
public static void Main(string[] args)
{
StartProvider.LaunchMklRt(max, path);
// rest of the code;
}
}
```
where ```max``` is the max number of threads used by MKL (-1 to use the max number) and `path` is the path to `mkl_rt.dll`.
#### Linux Users
You first need to download [Intel's MKL](https://software.intel.com/en-us/mkl) libraries for Linux. Check that the folder contains `libmkl_rt.so` which is the main library used by BlasNet.
To set the provider to use `libmkl_rt.so` for the low level array you first need to make the libraries visible through the `LD_LIBRARY_PATH` variable.
To do so, add the path to Intel's libraries by running the following commands :
```
$ echo "/path/to/mkl/lib/" >> /etc/ld.so.conf.d/intel.conf
$ ldconfig
```
Now, to set the provider to use `libmkl_rt.so` for the low level operations place the following line at the beginning of your code :
```
using BlasNet;
public namespace Test
{
public static void Main(string[] args)
{
StartProvider.LaunchMklRt(max);
// rest of the code;
}
}
```
where `max` is the max number of threads used by MKL (-1 to use the max number).
## Nuget Package
We provide a Nuget Package of **BlasNet** to facilitate its use. It's available on [Nuget.org](https://www.nuget.org/packages/Proxem.BlasNet/).
Symbols are also available to facilitate debugging inside the package.
