Collatz is back online but there are a number of changes. First, all applications are OpenCL based including the nVidia and CPU applications. If you wish to use your CPU on this project, you will need either the Intel or AMD OpenCL driver installed. See the project home page for more info and links.Second, all new applications have been deployed for all platforms which do additional internal validation and also gets all platforms back to the exact same code base. They all use the same config file format so they can be optimized the same way as the v4.xx application.The validator will NOT accept data from versions as the output has changed slightly with the addition of v6.xx. While I hope there will be no problems with the new applications, I expect Murphy's Law will prevail.I still have work to do to be able to grant credit for any lost pending and in progress work units, but it is planned.
