Inizia confrontando gli esempi adattati clblasDgemm_future.jl e clblasDgemmRandomBufferFuture.jl con clblasSgemm_future.jl e clblasSgemmRandomBufferFuture.jl. Riproduci il MethodError con le versioni indicate di Julia, clBLAS e CLBLAS.jl, quindi verifica che entrambi gli esempi in doppia precisione vengano eseguiti correttamente senza gli errori segnalati.

Descrizione

I'm trying to use GEMM with double-precision floats, but that doesn't seem supported? I tried a straight-forward adaptation of the clblasSgemm_future.jl and clblasSgemmRandomBufferFuture.jl examples to use Float64/cl.cl_double, but I get the following errors.

I am using Linux Mint 17.2 (essentially Ubuntu 14.04), clBLAS v2.6, Julia v0.4, latest CLBLAS.jl master (currently 1555379).
