2 years ago This is a zlib-compatible library that makes use of IBM's hardware accelerator for gzip, NX, which is available on their POWER9 chips.
- Characteristics: fast, good compression (see figure).
- Usage scenarios: you have too much money or you happen to have a POWER9 machine, and you want to compress things.
These results are from compressing a 100 MB binary blob.
I'm not 100% sure what you mean by warehouse, but I'll interpret it as "repository". The address that the code is from, https://github.com/libnxz/power-gzip, is the address cited in IBM's original paper about the compressor: https://dl.acm.org/doi/10.1109/ISCA45697.2020.00012.
Can you describe the characteristics and usage scenarios of this compression algorithm in detail? And introduce that the warehouse you obtained is the official warehouse address.
