420. 热力学采样单元:新型计算硬件

from 知为谁 · host 知为谁

这些来源提供了关于 Extropic 热力学采样单元 (TSU) 及其原型硬件的详细信息。TSU 是一种新型概率计算机,旨在通过执行 Gibbs 采样算法 来高效运行生成式 AI 模型。第一个公开的硬件平台是 实验测试与研究平台 0 (XTR-0),它包括 X0 芯片,该芯片验证了使用标准晶体管工艺制造 概率电路 的可行性。与当今 AI 系统中使用的确定性逻辑电路不同,TSU 使用 概率电路(例如 pbit、pdit 和 pmode)进行 能量模型 (EBM) 的采样。Extropic 旨在通过 去噪热力学模型 (DTM) 优化 TSU,并计划在未来发布 Z1 TSU 芯片,以进一步提高能源效率并扩大规模。内容来源:https://extropic.ai/writing/tsu-101-an-entirely-new-type-of-computing-hardwarehttps://extropic.ai/writing/inside-x0-and-xtr-0
