Brahma.FSharp provides a way to utilize GPGPU in your F# programs. It is based on F# quotations to OpenCL translation.

• Utilization of OpenCL for communication with GPU. So, you can work not only with NVIDIA devices but with any device which supports OpenCL (e.g. with AMD or Intel devices).
• Not only primitive types, but also discriminated unions, structs, records are supported.
• Pattern matching, mutable and immutable bindings, nested bindings are supported.
• Custom atomics.
• Fine-grained memory management and kernels compilation process.
• Mailbox processor based interface for communication with devices.

More details are available here.

Install Brahma.FSharp by running:

dotnet add package Brahma.FSharp

Setup BRAHMA_OCL_PATH environment variable to opencl.dll location if it differs from default.

open Brahma.FSharp

let device = ClDevice.GetFirstAppropriateDevice()
let context = RuntimeContext(device)

let kernel =
    <@
        fun (range: Range1D) (buffer: int clarray) ->
            let gid = range.GlobalID0
            buffer.[gid] <- buffer.[gid] + 1
    @>

opencl {
    use! buffer = ClArray.alloc<int> 1024
    do! runCommand kernel <| fun kernel ->
        kernel
        <| Range1D(1024, 256)
        <| buffer

    return! ClArray.toHost buffer
}
|> ClTask.runSync context

Contributions, issues and feature requests are welcome. Feel free to check issues page if you want to contribute.

Make sure the following requirements are installed on your system:

• dotnet SDK 7.0 or higher
• OpenCL-compatible device and respective OpenCL driver

To build and run all tests:

• on Windows

build.cmd 

• on Linux/macOS

./build.sh 

To find more options look at MiniScaffold. We use it in our project.

The release process is automated: NuGet packages publishing process is triggered by tag pushing to any branch. To release new vesion one should

1. Add relese notes to CHANGELOG
2. Run ./build.sh Release [version] (on local machine)
