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.

Quick Start

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 ->
        <| Range1D(1024, 256)
        <| buffer

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