Transcoding Billions of Unicode Characters per Second with SIMD (2022)
2 months ago
- Text is commonly represented using Unicode formats (UTF-8 and UTF-16) in software.
- Transcoding between UTF-8 and UTF-16 is a frequent operation but is slower than modern disks and networks.
- Existing transcoding functions underutilize SIMD instructions available on commodity processors.
- The authors design transcoding algorithms that leverage SIMD instructions to significantly increase speed on x64 and ARM systems.
- The optimized software is provided as a free, open source library for reproducibility.
TOP500 at ISC’26: We have a New Number 1 Supercomputer
3 months ago
- LineShine supercomputer from Shenzhen, China becomes the new number 1 on the TOP500 list, marking China's first submission in 9 years.
- The system is CPU-only, using the Armv9-compliant LX2 CPU with 304 cores, delivering 60.3 TFLOP/s per CPU and a total of 2.198 Exaflops sustained FP64 performance.
- LineShine also ranks number 1 in the HPCG benchmark with 22.004 Petaflops/second, surpassing El Capitan.
- A new number 6 system, HPC7 from Eni in Italy, uses AMD Instinct MI300A APUs, giving Italy more TOP500 compute than any other European country.
- Fugaku, the former number 1, drops to number 9 but remains number 3 on the HPCG list, showing its lasting efficiency.
- The Green500 Top 10 list remains unchanged for the first time, though overall HPC efficiency has improved due to retirements of older systems.
- The TOP500 list will now be managed by ACM SIGHPC, providing DOI numbers for easier referencing.
- Questions arise about whether China will submit other exascale systems and if this will increase U.S. DOE funding for supercomputers.
- The absence of large AI systems like xAI's Colossus 2 from the TOP500 raises curiosity about their benchmarking practices.
