Limitations for Windows Server 2008 and Windows Server 2012 The following are features that are not currently supported or have limited support in this driver release: NVIDIA Control Panel Display Category The Graph tab on the Adjust Desktop Color Settings page is not available. Release 346 Quadro & NVS Professional Drivers for Windows - Version RN-WQ _v01 6 Chapter 02 : RELEASE 346 DRIVER CHANGES Advanced Instructions for this Release This section clarifies instructions for successfully accomplishing the following tasks: Turning Off V-Sync to Boost Performance NVIDIA Application Configuration Engine (ACE) SLI Multi-OS GPU Assignment in System Virtualization Using the WDDM Driver Model with Tesla GPU GOMs Turning Off V-Sync to Boost Performance To get the best benchmark and application performance measurements, turn V-Sync off as follows: 1 Open the NVIDIA Control Panel and make sure that Advanced Settings is selected from the control panel tool bar. 2 From the Select a Task pane, under 3D Settings, click Manage 3D Settings, then click the Global Settings tab. 3 From the Global presets pull-down menu, select Base profile. 4 From the Settings list box, select Vertical sync and change its value to Force off, then click Apply. 5 From the Global presets pull-down menu, select 3D App - Default Global Settings (the driver s default profile) or use the application profile that matches the application you are testing, then click Apply. Be sure to close the NVIDIA Control Panel completely leaving it open will affect benchmark and application performance. Release 346 Quadro & NVS Professional Drivers for Windows - Version RN-WQ _v01 7 Chapter 02 : RELEASE 346 DRIVER CHANGES NVIDIA Application Configuration Engine (ACE) This driver includes the NVIDIA Application Configuration Engine (ACE), which automatically detects the workstation application and configures the appropriate profile settings in the NVIDIA Control Panel. See the NVIDIA Quadro Professional Drivers: NVIDIA Control Panel Quick Start Guide for more information about this feature. SLI Multi-OS GPU Assignment in System Virtualization On systems with two or more graphics cards installed, this driver supports a hypervisor's ability to directly assign GPUs to guest virtual machines (VMs). This direct assignment allows each guest VM to run on their own operating system with their own GPU and driver. The assignment allows full GPU performance and functionality in the guest VM. Hardware Platform Requirements To make use of GPU passthrough with virtual machines running Windows and Linux, the hardware platform must support the following features: A CPU with hardware-assisted instruction set virtualization: Intel VT-x or AMD-V. Platform support for I/O DMA remapping. On Intel platforms the DMA remapper technology is called Intel VT-d. On AMD platforms it is called AMD IOMMU. Support for these feature varies by processor family, product, and system, and should be verified at the manufacturer's website. Supported Hypervisors The following hypervisors are supported: Hypervisor Citrix XenServer VMware vsphere (ESX / ESXi) Parallels Workstation Extreme Notes Version 6.0 and later. Version 5.1 and later. Version 4 and later Release 346 Quadro & NVS Professional Drivers for Windows - Version RN-WQ _v01 8 Chapter 02 : RELEASE 346 DRIVER CHANGES Supported Graphics Cards The following GPUs are supported for device passthrough: GPU Family Boards supported Kepler GRID: K1, K2, K520, K340 Quadro: K2000, K4000, K5000, K6000 Tesla: K10, K20, K20x, K20Xm, K20c, K20s, K40m, K40c, K40s, K40st, K40t, K80 Fermi Quadro: 2000, 4000, 5000, 6000 Quadro-MXM: 1000M, 3000M Tesla: C2050, C2075, M2050, M2070, M2070Q Notes and Known Issues VMware PCI I/O hole may need to be changed for Windows 64-bit VMs. Windows 64-bit VMs may require that you edit the VM configuration file to configure a larger PCI I/O hole for the GPU. Access Control Services is required on some switches. Starting with ESX 5.0 Update 1, Access Control Services (ACS) is required on any switches in the PCIe hierarchy above a PCIe device that is to be used for passthrough. If ACS is not present, ESX will not allow the device to be assigned directly to a VM. To allow assignment of devices below switches that do not support ACS, you can disable the ACS check as follows: esxcfg-advcfg -k true disableacscheck Configuring passthrough to a Windows Server 2008R2 VM. The VMware WDDM driver must be manually installed on Windows Server 2008 R2. Follow the steps provided at # MSI translation must be disabled. Blue-screen crashes may occur on VMs with assigned GPUs if MSI is initially enabled for passthrough devices. To avoid this issue, disable MSI translation by setting pcipassthru0.msienabled = FALSE in the VM s VMX file. Citrix Xenserver XenServer 6.1 workaround for 64-bit MMIO failures on PCI passthrough. Release 346 Quadro & NVS Professional Drivers for Windows - Version RN-WQ _v01 9 Chapter 02 : RELEASE 346 DRIVER CHANGES Dom0 kernel may relocate GPU BARs to an invalid location immediately beyond the end of physical RAM. There are two workaround options to address this condition: Workaround option #1: Add pci=use_crs to the kernel parameters by running the following command in Dom0: /opt/xensource/libexec/xen-cmdline --set-dom0 pci=use_crs Workaround option #2: Install the hotfix provided by Citrix at support.citrix.com/article/ctx137645): Multi-Monitor Support on GRID Multi-monitor support on GRID boards K1 and K2 requires the following VBIOS versions: GRID K1: AF or later GRID K2: 80:04:BA:00.00 or later Release 346 Quadro & NVS Professional Drivers for Windows - Version RN-WQ _v01 10 Chapter 02 : RELEASE 346 DRIVER CHANGES Using the WDDM Driver Model with Tesla GPU GOMs Tesla GPU Operation Modes Tesla K20X and K20 GPU Accelerators offer the ability to specify the GPU operation mode using NV-SMI/NVML. (refer to: https://developer.nvidia.com/nvidiamanagement-library-nvml). By setting the GPU operation mode, developers can selectively turn off certain features in the GPU to get the best performance per watt for certain workloads. The following are the supported GOMs: Compute-Only: For running compute tasks only. By default the Tesla K20X and K20 accelerator boards ship in this mode. Low-Double Precision: For graphics applications that don t require high bandwidth double precision. This is recommended for workloads that are not sensitive to double precision but at the same time need graphics capabilities. All On: This is recommended only when the workload needs full double precision as well as graphics capabilities. WDDM and TCC Driver Models Along with the GPU operation mode, the developer needs to select the compatible driver model for the Tesla K20X and K20. Tesla Compute Cluster (TCC): Optimized for running compute workloads. Windows Device Driver Model (WDDM): Designed for graphics application and not recommended for compute workloads. Release 346 Quadro & NVS Professional Drivers for Windows - Version RN-WQ _v01 11 Chapter 02 : RELEASE 346 DRIVER CHANGES Compatibility Between GOM and Driver Models Table 1 shows which GPU operation modes are compatible with which driver models. Table 1 GOM and Driver Model Compatibility GOM TCC Driver Model WDDM Driver Model Use Case Support All On YES YES All use cases are supported. Compute-Only YES NO The following are unsupported: X11 and those that require X11 (GLInterop, OCL conformance and VIPER) 32-bit Windows OS Low Double Precision YES YES All use cases supported. The compute-only GOM is supported only on the TCC driver model, while the WDDM driver model supports only GOM modes that enable graphics. The compute-only GOM and WDDM are incompatible and should not be used simultaneously. The Tesla K20 Active Accelerators for workstations ship in compute-only mode and cannot be modified. Therefore, use only the TCC driver model with these products. Using the WDDM Driver Model To use the WDDM driver model with Tesla K20x and K20 GPU Accelerators for servers, first switch the GOM mode from compute-only to All On, then switch from TCC to WDDM. Do not attempt to specify the driver model by editing the registry. Doing so can result in compute-only GOM and WDDM being configured simultaneously, which might require a clean installation of the driver to fix. Always use NVIDIA-provided tools to specify a processing mode or to switch between driver models. Such tools include nvidia-smi or the NVIDIA Control Panel- Manage Maximus Settings page. These tools provide warnings in the case of a conflict.
