U18M 零 IP8 格式如何在节省算力和内存的情况下提升效率？ U18M 零 IP8 格式通过将权重数据从 128 乘 128 量化块拆分成 128 乘 4 的小 块，从而减少显存占用和计算开销，同时保持计算精度。传统的 IP8 权重需要 大量显存在 128 乘 128 块中反复使用，而新的 U18M 零 IP8 则通过更小的数 据块减少了这些需求。此外，新方法还优化了反向量化过程，进一步节省存储、 显存和计算资源。这些改进使得新格式能够在保持高精度的同时，大幅提高训 练和推理效率。 大厂怎么看 DeepSeek-V3.120250824 摘要 Deepseek 定义 U18M 零 IP8 格式，旨在为国产芯片制定新标准，降低 训练侧显存占用 20%-30%，提升训练效率 30%-40%，并指导下一代 国产芯片设计，有望通过 OCP 扩展为国产芯片的 RP8 协议标准。 U18M 零 IP8 通过拆分量化块减少显存占用和计算开销，优化反向量化 过程，在保持高精度的前提下提高训练和推理效率，并采用混合精度策 略平衡性能与精度，敏感参数保留高精度计算（如 FP16）。 SP8 数据格式将提升国产大模型训练效率， ...

Group 1: Central Budget Investment - The central budget investment of 735 billion yuan has been largely allocated, focusing on modern industrial systems, infrastructure, new urbanization, rural revitalization, regional development, green development, and social welfare projects [1] - This year's investment direction has been optimized, increasing support for social welfare and reducing the financial burden on local governments [1][2] - The early allocation of central budget investment reflects a proactive fiscal policy in response to economic pressures, particularly in the real estate sector and insufficient domestic demand [1] Group 2: Economic Performance of Central Provinces - The economic performance of six central provinces shows a positive trend, with five provinces exceeding the national growth rate of 5.3% [3] - Hubei province leads with a GDP growth rate of 6.2%, while Henan follows at 5.7%, indicating strong investment, consumption, and export activities [3][4] - The economic disparity among these provinces is notable, with Shanxi facing challenges due to its reliance on coal and a less favorable business environment [4] Group 3: U.S. Manufacturing and Services Sector - The U.S. Markit manufacturing PMI fell to 49.5, indicating contraction, while the services PMI rose to 55.2, reflecting a divergence in economic performance [5][6] - The overall economic growth in the U.S. is uneven, with the services sector supporting growth despite manufacturing challenges [7] Group 4: Bank Deposit Rates - Average interest rates for short-term deposits have dropped significantly, with 3-month deposit rates entering the "0" range [8] - The decline in deposit rates is linked to a broader trend of decreasing loan rates, impacting banks' profitability [9] Group 5: Intel's Financial Performance - Intel reported a second-quarter revenue of $12.9 billion but faced a significant loss of $2.9 billion, a 81% increase in losses year-over-year [10] - The new CEO has shifted the company's strategy away from aggressive expansion, focusing on confirmed customer orders for future investments [10][11] Group 6: Country Garden's Debt Restructuring - Country Garden is expected to complete its overseas debt restructuring by the end of the year, having reached an agreement with bondholders for a $178 million compensation payment [12][13] - The restructuring plan has gained support from over 75% of bondholders, providing the company with a critical opportunity to alleviate its debt burden [13] Group 7: Chinese Companies Listing in the U.S. - There has been a significant increase in Chinese companies listing in the U.S., with 50 companies going public this year, a 78.57% increase from last year [14][15] - Despite the increase in listings, the total fundraising amount has decreased by 57.91%, indicating a shift in the fundraising landscape [14] Group 8: Stock Market Performance - The stock market experienced fluctuations, with the Shanghai Composite Index closing down 0.33% amid mixed sector performance [16][17] - The market is showing signs of increased activity, with a notable rise in trading volume and a rotation of sector performance [17]
