CLBLAS

CLBLAS integration for Julia

Readme

CLBLAS.jl

Build Status

AMD clBLAS bindings for Julia.

Current status

  • Low-level bindings
  • Partial implementation of high-level API similar to Base.LinAlg.BLAS

Example

using OpenCL
import OpenCL.cl.CLArray
import CLBLAS
const clblas = CLBLAS


clblas.setup()
device, ctx, queue = clblas.get_next_compute_context()
alpha = 1.0
beta = 0.0

hA = rand(5, 10)
hB = rand(10, 5)
A = CLArray(queue, hA)
B = CLArray(queue, hB)
C = cl.zeros(queue, 5, 5)

clblas.gemm!('N', 'N', alpha, A, B, beta, C)
hC = cl.to_host(C)
if isapprox(hC, hA * hB)
    info("Success!")
else
    error("Results diverged")
end

Caveats

  • Complex64/CL_float2 doesn't work by default. This is caused by some weird incompatibility between clang (default for Julia) and gcc (default for clBLAS), so the only way to fix it right now is to manually compile clBLAS using clang,
