6. as started Removal of RealityServer is done by simply deleting the unpacked directory Please see the README file for details of the contents of that directory Firewalls Operation of the RealityServer involves network connections On Windows there are often firewalls installed such as the generic Windows firewall that block network connections in a way that makes it impossible for the blocked program to detect or react to the problem RealityServer cannot be run on a machine that requires this kind of firewall protection unless the firewall is manually instructed to allow to open the port listening for incoming connections on the configured HTTP port Network Buffers For maximum performance of the HTTP server on some Linux systems the possible size of network buffers must be increased because the default values are too low 256 kB Please use the following lines to increase them sysctl w net core rmemmax 8388608 sysctl w net core wmemmax 8388608 These settings are reset when rebooting To make them permanent add these lines to the file etc sysctl conf net core wmemmax 8388608 net core rmemmax 8388608 Software Protection Manager SPM See the separate SPM installation guide The software protection manager manages the software licenses that are reguired by RealityServer The RealityServer will not run if no licenses are available The RealityServer Developer Edition does not need an SPM installation

11. s Under Windows you configure the ECC functionality from the NVIDIA Control Panel usually available by right clicking on your desktop and selecting the NVIDIA Control Panel item You may need to enable the Advanced Configuration mode if asked In the panel on the left labelled Select a Task navigate to the Workstation section and select Change ECC state from this item you can deselect ECC for the GPUs in your system After changing the ECC state please reboot your system for the changes to take effect Note that the reguired commands and descriptions change from time to time with updated drivers please refer to the relevant NVIDIA documentation for further information on how to disable ECC functionality on your GPU Linux irgpoll Kernel Option On certain machines and configurations in particular machines with 8 or more GPUs you may see messages such as this during the use of RealityServer when rendering with iray Disabling IRO 194 irg 178 nobody cared try booting with the irgpoll option These messages are usually visible on the console as well as in the var log messages output on most Linux distributions If you encounter these messages it is very likely that you will also encounter severely degraded performance with GPU accelerated iray rendering If and only if you encounter this message you should enable the Linux Kernel irqpoll option to prevent these issues The process will differ dependin
