yaqi-zhao opened a new issue, #14684:
URL: https://github.com/apache/arrow/issues/14684
We want to add new codes to enable a new RLE Decoding path by using Intel®
In-Memory Analytics Accelerator (Intel® IAA). The new solution provides in
general higher performance than the current solution, and also consumes less
CPU.
Intel® In-Memory Analytics Accelerator (Intel® IAA) is a hardware
accelerator available in the upcoming generation of Intel® Xeon® Scalable
processors ("Sapphire Rapids"). Its goal is to speed up common operations in
analytics like data (de)compression and filtering.
We are concerned about 3 issues:
1. Since IAA is a new accelerator in next-generation processors which will
be published soon, the current machine running CI cannot support this feature.
I don’t know if it is acceptable that we run the CI offline, maybe on Intel’s
lab environment.
2. [Intel® Query Processing Library (QPL)](https://github.com/intel/qpl)
is a library to access the hardware accelerator IAA, is it acceptable to added
the dependency in the tool chain?
3. Do you think the work is valuable?
Thank you!
