OpenBlasSharp
The purpose of this project is to provide a .NET wrapper for OpenBLAS.
Installation
The NuGet package is available.
This package does not include the native DLL.
You must download the compiled binary and put libopenblas.dll
at the directory of the executable file.
All the classes are in the OpenBlasSharp
namespace.
using OpenBlasSharp;
Examples
Dot product
var len = 3;
var rnd = new Random(42);
var x = Enumerable.Range(0, len).Select(i => rnd.NextDouble()).ToArray();
var y = Enumerable.Range(0, len).Select(i => rnd.NextDouble()).ToArray();
fixed (double* px = x)
fixed (double* py = y)
{
var result = Blas.Ddot(len, px, 1, py, 1);
}
Matrix multiplication
var m = 3;
var n = 5;
var k = 4;
var rnd = new Random(42);
var a = Enumerable.Range(0, m * k).Select(i => rnd.NextDouble()).ToArray();
var b = Enumerable.Range(0, k * n).Select(i => rnd.NextDouble()).ToArray();
var c = new double[m * n];
fixed (double* pa = a)
fixed (double* pb = b)
fixed (double* pc = c)
{
Blas.Dgemm(
Order.ColMajor,
Transpose.NoTrans,
Transpose.NoTrans,
m, n, k,
1.0,
pa, m,
pb, k,
1.0,
pc, m);
}
Singular value decomposition
var m = 4;
var n = 3;
var rnd = new Random(42);
var a = Enumerable.Range(0, m * n).Select(i => rnd.NextDouble()).ToArray();
var s = new double[Math.Min(m, n)];
var u = new double[m * m];
var vt = new double[n * n];
var work = new double[Math.Min(m, n) - 1];
fixed (double* pa = a)
fixed (double* ps = s)
fixed (double* pu = u)
fixed (double* pvt = vt)
fixed (double* pwork = work)
{
Lapack.Dgesvd(
MatrixLayout.ColMajor,
'A', 'A',
m, n,
pa, m,
ps,
pu, m,
pvt, n,
pwork);
}
OpenBLAS specific functions
var numThreads = OpenBlas.GetNumThreads();
Development status
- Doc comments for the BLAS functions are missing.
- Low-level LAPACK functions with the
_work
suffix are not supported. - LAPACK functions that require function pointers are not supported.
