With this objective in mind: does it make sense for non-ATI-crunchers to participate in Albert? CUDA and CPU results can be used to validate OpenCL results, but then ...? I'm missing a little information about this. I'm getting WUs for two of my systems but the question remains: does Albert need / want non-ATI-Crunchers? Stephan ID: 111426 · Reply Quote

Were it only for developing new versions of the existing BRP4 application we could as well have tested it on the main project. But it's not. The OpenCL stuff requires not only new application binaries, but (for Einstein@Home) a couple of modifications to the server code, and currently special workunits, too. Apart from validating the results we also need to test how these changes work with the existing application verions. However, currently we're getting by far the most results back from Windows CUDA apps (twice as many as from all other app versions together). We certainly need a few of these, but probably not that much. BM ID: 111430 · Reply Quote

But are those tasks identical or is there a difference?. I am glad to say I can see graphics on both. Tullio ID: 111462 · Reply Quote

Indeed these are a bit different from the BRP4 ones on Einstein. BM ID: 111466 · Reply Quote

This new series will have much reduced power consumptions, and improved performance over the 6000 series. Or, you can see if you can find the new entry level ATI 6930. ID: 111482 · Reply Quote
