SK Telecom doubles capacity of its AI service's supercomputer Titan

South Korea's SK Telecom Co. on Sunday said it had doubled the processing capacity of its supercomputer Titan, the brain of its artificial intelligence (AI) service "A-dot" (A.).

To drive immense AI that handles billions of parameters, a supercomputer needs the infrastructure to process massive amounts of data swiftly and accurately. Launched in 2021 and run by SK Telecom, Titan last year was the first in Korea to rank among the world's top 100 supercomputers at 85th.

SK Telecom said it doubled the Titan's number of graphics processing units known as Nvidia A100 to 1,040, giving the supercomputer a capacity of 17.1 petaflops. One petaflop equals one quadrillion mathematical operations per second, so 17.1 petaflops means a supercomputer can process 17.1 quadrillion operations per second.

With A-dot already applying tens of billions of parameters to commercial services, the company pledged to further boost the AI service's learning ability by doubling its parameter volume.

SK Telecom is applying the A-dot function to select domestic media platforms such as the music streaming service Flo, mobility tool T-map and video streaming app Waave.

"We will seek to stand at the forefront of AI technology leadership through aggressive R&D investment, infrastructure expansion and talent recruitment," said Kim Young-joon, head of SK Telecom's A-dot unit.
