BLAS optimization by CUBLAS

Dear colleagues! In early 2009 there was a discussion about fast BLAS library initiated by Sachin. He reported a faster BLAS library made by Nvidia CUBLAS library. Uwe Ligges showed an interest for placing the optimized rblas.dll into windows/contrib section managed by him. Unfortunately there is no any CUBLAS version of rblas.dll in this section at present. So, is anybody interested in CUBLAS optimization of rblas now?
We are, but we are primarily interested in maintainable Open Source solutions. No one made available such a version of Rblas.dll (sic).
In my opinion current directions (packages) of high-performance and parallel computing with R suffer from grave shortcomings: all GPU optimization is made by introducing more and more optimized functions coexisting with original ones. This hard way has been chosen for Matlab too. It complicates R as a language. So, the idea of optimizing BLAS (especially by CUBLAS) seems to overcome the mentioned shortcomings. It might be remarkable to make some efforts to this way of high-performance computing. Yuri Possokhov [[alternative HTML version deleted]]
