The next year, PacBio developed a new method to allow multiple sequencing passes on the same DNA molecule. Double stranded DNA templates were ligated to two single stranded adapters, creating what the company called a “SMRTbell template.” Sequencing began at a primer on one of the adaptors and could proceed multiple times per molecule due to circularization, in a process called rolling-circle amplification. This helped reduce PacBio’s error rates significantly.

Sophia, an Nvidia partner, has designed modular server racks with integrated solar panels it calls TILES, which are 1 meter by 1 meter in area and a few centimeters in depth. By adopting this thin form factor, DeMillo says that processors can sit against a passive heat spreader, eliminating the need for active cooling. He expects 92% of the power it generates will go to processing, a significant gain on traditional designs. This design requires, however, a sophisticated software management system to balance activity across the processors.
