"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:
https://en.bitcoin.it/wiki/Mining_hardware_comparison
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!

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

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