According to wikipedia [1], they planned to use their Loongson MIPS chips for some of the Dawning supercomputers, but later reconsidered. I'd guess using Loongson MIPS didn't make any sense given its poor performance compared to Intel CPUs. It will take quite some time to get to a modern CPU design that can compete with Intel but it seems Loongson development continues even without being able to produce comptetive products for now. For example, Lemote.com seems to be selling Loongson 3A server blades [2]. For HPC applications Loongson 3B would have much better performance due to implementing 256-bit vector instructions (maybe similar to intel AVX), I wonder whether these can be readily bought anywhere in china. Loongson 3C would bring quite some performance boost by finally switching to a more modern process technology (28nm instead of 65nm), but google doesn't show any results that'd indicate it's produced already.
