Dealing With AI/ML Uncertainty
By Karen Heyman - 25 Apr, 2024 - Comments: 0

Despite their widespread popularity, large language models (LLMs) have several well-known design issues, the most notorious being hallucinations, in which an LLM tries to pass off its statistics-based concoctions as real-world facts. Hallucinations are examples of a fundamental, underlying issue with LLMs. The inner workings of LLMs, as well as other deep neural nets (DNNs), are only partly kno... » read more

Applied Materials may scale back or cancel its $4 billion new Silicon Valley R&D facility in light of the U.S. government's recent announcement to reduce funding for construction, modernization, or expansion of semiconductor research and development (R&D) facilities in the United States, according to the San Francisco Chronicle. TSMC could receive up to $6.6 billion in direct funding... » read more

BOLT Optimization Technology Could Bring Obvious Performance Uplift On Arm Server
By Bolt Liu - 11 Apr, 2024 - Comments: 0

BOLT is a post-link optimization technology which builds on LLVM framework, which leverages perf tool to collection sampling data and convert the executable into an optimized version. After evaluating BOLT on several workloads such as MySQL, Redis, memcached and nginx on Arm server, we could see obvious performance uplift. This blog post illustrates the methods used to enable BOLT and per... » read more

Performance Boost In Powerful Real-Time Cortex-R Processor Using Data Prefetch Control
By Arm - 10 Apr, 2024 - Comments: 0

High-performance processors employ hardware data prefetching to reduce the negative performance impact of large main memory latencies. An effective prefetching mechanism can improve cache hit rate significantly. Data prefetching boosts the execution performance by fetching data before it is needed. While prefetching improves performance substantially on many programs, it can significantly red... » read more
