The GPUPI benchmark is a brainchild of Matthias from Overclockers.at. It requires CUDA or OpenCL capable hardware and features a fantastic integration with the HWBOT rankings. The benchmark is getting more and more used by overclockers and reviews, so continuous improvements and bug-fixes are welcome. Version 2.2 features a couple of important updates and will be mandatory for HWBOT validation in the near future.

Changelog:

• - Progress bar for the submission upload including the possibility to abort
• - Split submission into two dialogs: Online submission and data file saving (will make more sense in future releases)
• - Timeout set to 30 seconds for reaching the HWBOT servers (in case they are down)
• - Better file names for data files
• - Bugfix for Windows XP timer bug
• - Improved timer validity check and added Skylake's 24 Hz HPET resolution
• - Better error reporting for OpenCL context creation
• - Added platform vendor name (if necessary) to OpenCL ready message to better distinguish the platform that a run was started with
• - Fixed possible cheating in slowest result competitions by aborting a run when system is set to sleep mode/li>
• - Added execution states to the calculation thread to avoid sleep mode/hibernation (monitor will still be able to go into sleep mode, but that won't affect the benchmark run)
• - Bugfix for repeated online submission and hardware detection via COM queries
• - Legacy version uses CUDA toolkit 6.5 again, because 6.0 could not calculate valid results on serveral old graphics cards due to a precision bug
• - Compiled with newest Visual Studio 2013 - Update 5

In a brief section, Matthias also talks about some upcoming plans for GPUPI. Firstly, there's upcoming integration with CPU-Z which will feature improved hardware detection. This could possibly mean GPUPI will be a major option for low-clock challenges. Also planned is improved support for HWBOT competitions, similar to what the HWBOT Prime for Android currently offers with direct submission to competitions from the benchmark application.
