我目前的设置是我有一张 Nvidia 卡和一张 AMD（兼容 OpenCl 2.0）APU。
我正在运行 Fedora 20。
目的是测试 APU 与 [CPU+显卡] 之间的速度差异。通过查询可用的平台，我得到：
1.1 Name : AMD Accelerated Parallel Processing
1.2 Vendor : Advanced Micro Devices, Inc.
1.3 Version : OpenCL 1.2 AMD-APP (1445.5)
1.4 Profile : FULL_PROFILE
2.1 Name : NVIDIA CUDA
2.2 Vendor : NVIDIA Corporation
2.3 Version : OpenCL 1.1 CUDA 6.5.19
2.4 Profile : FULL_PROFILE
NVidia 卡只有 OpenCL v1.1 我对此并不感到惊讶，但 AMD APU 确实应该兼容 OpenCL v2.0。
我已在以前的内核（不是当前内核）上安装了 AMD App SDK，但我不明白为什么当前内核上的信息没有更改。谁能帮助我确保我获得正确的信息
