MEMS Clocks: Saving Power For AI
AI changes everything in data centers: a new prosecution Chipsnew Cooling techniquesAnd new storage engines. Now eVen how to maintain time started to change, with an advertisement from Sitime developed by the company A new watch has been improved for the burdens of artificial intelligence.
The company says that the development will lead to great energy savings and reduce the costs of training of artificial intelligence and inference. Sitime managed to achieve these savings using micro -electric systems (MEMS) as the component of the basic time preservation instead of traditional quartz crystals.
Almost every part of the computer has a kind of watch. Central processing units, graphics processing units, network interface cards, keys, and even active connections sometimes contain their time consisting. For more traditional computing work burdens, these watches are usually divided into two categories: rapid watches or watches of specifically specified time that are well simultaneously through multiple graphics processing units (or central processing units), says Ian Kubis, chief analyst in Moore and working with control.
“The problem with artificial intelligence is that it does both,” says Cutress. “You want to walk your slice as quickly as possible, but then you also want to synchronize 100,000 chips.”
The SUPER-TCXO clock in Sitime combines very stable and well-intended watch functions in one device, providing a good synchron component In the 800 GB of frequency domain width, in the chip of this quarter.
Better timing leads to energy savings
Artificial intelligence is a thirsty monster. However, expensive graphics processing units with energy up to 57 percent of the time awaiting the next data boost. If it is possible to provide data more quickly, graphics processing units can be used in smaller quantities more and more.
“You need a faster frequency range. PIIUUUUUHIOUSH Sevalia, CEO of Marketing at Sitime, says, because you need a faster frequency range, you need a better timing.
In addition, one can keep a lot of energy if it is possible to put graphics processing units in stillness while waiting for more data, says Cutress. This, also, requires a more accurate timing, so that the sleep seizure cycle can quickly occur enough to keep pace with the data flow.
For artificial intelligence, the watches not only need to be more accurate, but are also completely synchronized by many graphics processing units. The large AI models divide their duties between many graphics processing units, with each one make a small part of the account. Then, its results are sewn together. If the graphics processing unit is left behind, the entire account will have to wait for that node. In other words, the account speeds only the weakest link. All graphics processing units are still operating at the level of graphics processing units while waiting, so any such delay leads to energy loss.
High time for MEMS
The timing should be accurate, good and strong synchronization – any mechanical vibrations or temperature fluctuations should be compensated to ensure that the account is not eliminated. Super-TCXO at Sitime aims to combine all three requirements in one device.
Cival says that the use of MEMS oscillator instead of traditional quartz makes this mixture possible. The quartz oscillator uses vibrations of quartz crystals that are manufactured accurately – similar to a thorn. On the contrary, the MEMS fluctuations are manufactured, not formed, for a frequency at a specific frequency. MEMS devices can be smaller, making them less sensitive to mechanical breeds. It can also be more accurate.
“The crystal massages have been present since the beginning of time, because Compute was something,” said Dave Alutavilla, President and lead analyst at Hottech Vision & Analysis, who also works with Society. We have improved this technology significantly from its inception. But MEMS takes it another step further than what can be the crystal. This is what I think is displaced in the market through this new technology is the old way to do things. “
MEMS SIMES solutions have already been made some success-SIMECON-X from NVIDIA already containing the Sitime.
Sevalia says he expects the need for MEMS timing devices. The company is already planning the highest frequency domain latitude, and they hope that their innovations will provide greater energy. “We are scratching the surface now in terms of knowing how much energy efficiency we can bring,” says Sevalia.
