+When both CUDA and OpenCL drivers are enabled, StarPU will launch an
|
|
|
+OpenCL worker only if CUDA is not already running on the GPU.
|
|
|
+This design choice was necessary as OpenCL and CUDA can not run at the
|
|
|
+same time on the same GPU, as there is currently no interoperability
|
|
|
+between them.
