According to wikipedia, the Tianhe-I is the fastest supercomputer in the world. It can perform operations at approximately 2.566 PetaFLOPS.

How many hashes per second could this beast create?

The PFLOPS cannot be directly related to GHashes/sec. However, from the current 3.869 THashes / sec we can divide it between the 750 MHashes/sec of a 6990. There is the equivalent of 5159x 6990s. Each one does roughly 6 TFLOPs which would come to around 30 PFLOPs total. Please note, again, that PFLOPs != Hashes/sec.

So in conclusion, we got over 11 Tianhe-I Tongue

"It is now equipped with 14,336 Xeon X5670 processors and 7,168 Nvidia Tesla M2050 general purpose GPUs"

You can look up the performance of those processors here:

M2050: 100 Mhash/s
X5630: 8 Mhash/s  (let's just guesstimate that the X5670 can do 10 Mhash/s)

So, Tianhe-1A can do approx. 0.72 Thash/s with GPUs alone, and approx. 0.86 Thash/s with GPU+CPU.

Not enough to do a double spending attack!
