随手摸下B200 (148SM)。Vector性能相比H100的提升比较常规(+25%)。全局原子CAS延迟是H100的2x，达到200ns，这大概就是MCM的代价。有意思的点在于wmma发生明显倒退，每SM性能回到了图形卡水平。本代大概只有tcgen05.mma可以跑出纸面tensor吞吐，这标志着计算卡重心逐渐转向类似NPU的TMEM？

The Singapore stock market has alternated between positive and negative finishes through the last five trading days since the end of the two-day winning streak in which it had added more than a dozen points or 0.4 percent. The Straits Times Index now sits just above the 3,060-point plateau and it's likely to see a narrow trading range on Monday.

The lead from Wall Street offers little clarity as the major averages opened lower on Friday and then bounced back and forth across the unchanged line, finally finishing mixed and little changed.The Dow added 33.18 points or 0.10 percent to finish at 34,798.00, while the NASDAQ eased 4.54 points or 0.03 percent to close at 15,047.70 and the S&P 500 rose 6.50 points or 0.15 percent to end at 4,455.48. For the week, the Dow rose 0.6 percent, the NASDAQ added 0.1 percent and the S&P gained 0.5 percent.The lackluster performance on Wall Street came on uncertainty about the outlook for the markets following recent volatility.
