"Fire-Flyer AI-HPC: A Cost-Effective Software-Hardware Co-Design for Deep Learning"

Abstract:

"The rapid progress in Deep Learning (DL) and Large Language Models (LLMs) has exponentially increased demands of computational power and bandwidth. This, combined with the high costs of faster computing chips and interconnects, has significantly inflated High Performance Computing (HPC) construction costs. To address these challenges, we introduce the Fire-Flyer AI-HPC architecture, a synergistic hardware-software co-design framework and its best practices. For DL training, we deployed the Fire-Flyer 2 with 10,000 PCIe A100 GPUs, achieved performance approximating the DGX-A100 while reducing costs by half and energy consumption by 40%. We specifically engineered HFReduce to accelerate allreduce communication and implemented numerous measures to keep our Computation-Storage Integrated Network congestion-free. Through our software stack, including HaiScale, 3FS, and HAI-Platform, we achieved substantial scalability by overlapping computation and communication. Our system-oriented experience from DL training provides valuable insights to drive future advancements in AI-HPC."

If you need some "Routing Graph" - check the pgRouting library https://pgrouting.org/

  "pgRouting library contains following features:
  All Pairs Shortest Path, Johnson’s Algorithm
  All Pairs Shortest Path, Floyd-Warshall Algorithm
  Shortest Path A*
  Bi-directional Dijkstra Shortest Path
  Bi-directional A\* Shortest Path
  Shortest Path Dijkstra
  Driving Distance
  K-Shortest Path, Multiple Alternative Paths
  K-Dijkstra, One to Many Shortest Path
  Traveling Sales Person
  Turn Restriction Shortest Path (TRSP)"\*

Is it normally preferred to use some library such as this over a more traditional approach of nested sets, adjacency lists or ltree module?




Probably, the results in the table are about 7 years old. For example, the table shows version 1.3.4 for zstd, which indicates that the results are outdated - currently, version 1.5.6 is the latest release ( https://github.com/facebook/zstd/releases/tag/v1.5.6 )

In my opinion, it is better to check the original repository: https://github.com/inikep/lzbench

or this: https://github.com/inikep/lzbench/blob/master/doc/lzbench20_...


Judging by the last link, the only options that are strictly superior to snappy in every sense are lz4 (as OP claimed) and zstd (levels -3 to +1). If compression speed is critical, then the default level of zstd compression in most big data tools (+3) might be the wrong one for you, but test on your own data, not Silesia.

" Individual and additive effects of vitamin D, omega-3 and exercise on DNA methylation clocks of biological aging in older adults from the DO-HEALTH trial

Abstract While observational studies and small pilot trials suggest that vitamin D, omega-3 and exercise may slow biological aging, larger clinical trials testing these treatments individually or in combination are lacking. Here, we report the results of a post hoc analysis among 777 participants of the DO-HEALTH trial on the effect of vitamin D (2,000 IU per day) and/or omega-3 (1 g per day) and/or a home exercise program on four next-generation DNA methylation (DNAm) measures of biological aging (PhenoAge, GrimAge, GrimAge2 and DunedinPACE) over 3 years. Omega-3 alone slowed the DNAm clocks PhenoAge, GrimAge2 and DunedinPACE, and all three treatments had additive benefits on PhenoAge. Overall, from baseline to year 3, standardized effects ranged from 0.16 to 0.32 units (2.9–3.8 months). In summary, our trial indicates a small protective effect of omega-3 treatment on slowing biological aging over 3 years across several clocks, with an additive protective effect of omega-3, vitamin D and exercise based on PhenoAge."
