Zama announces that it has reduced TFHE bootstrapping time to the microsecond level on GPUs. This is 56 times faster than the previous 53 ms CPU runtime. Currently, an incredible latency of around 945 µs has been achieved for 4 bit messages.
What is Zama’s contribution?
Since TFHE in 2018, the process has accelerated but @zama_fhe’s first CPU implementation still took 53 ms.
GPU optimizations, multi bit algorithms, compile time customizations and low level GPU improvements, this runtime has continuously decreased.
Finally, the 1 ms barrier has been broken and now we’re talking about microseconds.
