Selecting a GPU for OpenCL on the Mac Pro (Late 2013)

The Mac Pro (Late 2013) includes dual AMD FirePro workstation-class GPUs that are ideal for compute intensive tasks. This document describes how to query the GPUs and select one or both for use by OpenCL.

The Mac Pro (Late 2013) is different from other Macs as only the primary GPU provides output for the display. The secondary GPU provides additional processing capability and can perform OpenCL and off-screen OpenGL tasks without affecting the responsiveness of the user interface.

3D-Tech News Around The Web / SiSoftware Sandra SP2 2014.6.20.35
« on: May 26, 2014, 03:49:23 PM »
SP2 for SANDRA 2014 has been released!
It is a platform update that includes tool, SDK and library updates. Overall, the benchmark scores should still be within variation range - at least on the platforms we have tested.

* Platform update: XP, Server 2003 no longer supported

In order to move forward we have to change the environment, more specifically to VS 2012; we took this "opportunity" to remove support for XP and thus Server 2003 - thus supporting Kernel 6.0 and later only.

* CUDA SDK 6.0

Now that recent WHQL video drivers support it, we changed to SDK 6.0 and thus can include "Maxwell" support (SM50); note that SM10 support is deprecated.

* Additional fixes for AMD Kabini when paired with a dedicated GPU card (better scaling).

We’d like to share with you a project that was built during the R&D period of the Physically Based Shader and Reflection probes.

This benchmark project is one among several which helped us identify what improvements of functionality were necessary from an artist’s production perspective.

We compared offline to realtime rendering methods and output with the aim to achieve both an increase of visual quality, and a better streamlined, smoother production workflow for artists, which will open playful possibilities for graphics to be extended beyond realism to stylism.

Added CPU temperature monitoring (Intel Core 2 and newer Intel CPUs only), CPU usage, RAM usage and pagefile (commit charge) usage graphs to hardware monitoring module
Added CPU info to "i" window
Added basic monitoring for unsupported GPUs (e.g. Intel integrated iGPUs):
◎ Now GPU usage and videomemory usage can be monitored and displayed in On-Screen Display on any GPU, so you can use MSI Afterburner to monitor graphics subsystem on laptops without dedicated NVIDIA/AMD GPU
◎ Extended GPU usage monitoring for Intel integrated iGPUs. You can independently monitor usage of main GPU execution unit (labeled as "GPU usage") and MFX unit (labeled as "VID usage" to keep NVIDIA-styled GPU domains naming)
Now full list of currently active 3D processes is being displayed in On-Screen Display server info section in "i" window instead of one active 3D process before
Fixed GUI issue causing vertical slider to be rendered improperly in advanced application properties window under certain conditions
On-Screen Display text length limit has been extended from 256 bytes to 4 kilobytes
Added predefined fan speed curves list to the "Fan" tab in advanced application properties. The list allows you to select default curve on all cards and additional pre-defined curves (such as silent or performance fan speed curve) on some custom design MSI graphics cards
Added core voltage control for reference design NVIDIA GeForce GTX 7x0 series graphics cards
Added core voltage control for reference design AMD RADEON 7990 graphics cards with VT1556 voltage regulators

RestoreAfterSuspendedMode configuration file switch is no longer undocumented, now it is enabled by default and accessible via GUI in "General" tab in "Compatibility properties" section
Added "Reset display mode on applying unofficial overclocking" option to "AMD compatibility properties" section in "General" tab. This option can be used as a workaround for infamous flickering issue, caused by bug in AMD driver
Now MSI Afterburner displays path to driver registry key in "i" window
Now MSI Afterburner displays voltage regulator model and location information in "i" window
Now MSI Afterburner displays RivaTuner Statistics Server installation path and server version information in "i" window
Added French and Turkish localizations
Recompiled kernel mode driver to bypass false positive in driver verifier
Added workaround for missing tray icon when starting application while EXPLORER.EXE is not responding
Application tray icon is now being restored after restarting EXPLORER.EXE
Build number is now displayed in "i" window and in application tray icon tooltip
Localizable installer files for third party translators are now included in distributive in .\SDK\Localization\Installer folder
Now power users can display graphs in hardware monitoring window in multiple columns via configuration file
Framerate slider limit in "Videocapture" tab has been extended from 100 FPS to 120 FPS
Now flashing camera icon is being displayed in the top left corner of monitoring window when video is being captured
Added "Use dedicated encoder server" option to "Videocapture" tab
Added prerecording settings to "Videocapture" tab. You can select one of the following prerecording modes:
◎ Prerecord to a temporary file. This mode suits best for prerecording long videos (e.g. 10 minutes or more of H.264 video) or for prerecording videos with low compression ratio (e.g. lossless Lagarith video)
◎ Prerecord to RAM. This mode suits best for prerecording short videos (e.g. a couple minutes of H.264 video) and it provides a bit better performance than prerecord to file. Also, unlike prerecord to file, prerecord to RAM minimizes writes so it can increase the lifetime of SSD if you plan to use the prerecording frequently
Added "NV12 compression" to the list of available video formats to "Videocapture" tab. This format can be used to replace uncompressed video recording with fixed 2x compression ratio at the cost of some color information loss caused by RGB to YUV 4:2:0 color space conversion
Added "External plugin" to the list of available video formats to "Videocapture" tab. External plugins provide hardware accelerated H.264 video encoding support for Intel QuickSync, NVIDIA NVENC and AMD VCE platforms
Improved DirectInput hotkey handler minimizes the risk of losing hotkey functionality until application restart under certain conditions
RivaTuner Statistics Server has been upgraded to version 6.1.1:
◎ The server is no longer being distributed as a part of client applications like MSI Afterburner and EVGA Precision. Now it comes under generic RivaTuner Statistics Server name with own installer and can be optionally installed when necessary. The clients will automatically hide any server dependent functionality (such as On-Screen Display, framerate monitoring, automatic 2D/3D profiles management, screen and video capture and so on) when the server is not installed
Now RivaTuner Statistics Server installer is being started by MSI Afterburner installer to make installation process easier for beginners. The server distributive is being copied to .\Redist\RTSSSetup.exe during MSI Afterburner installation, so you may always install it later if necessary
