Abstract

fetched live from OpenAlex

Compression is a promising technique to increase effective capacity of caches. Due to latency overhead of decompression, most of previous studies applied compression to lower level caches. General-Purpose Graphics Processing Units (GPGPUs) are throughput oriented computing platforms which execute hundreds to thousands of threads, simultaneously. The massive number of threads makes GPGPUs less sensitive to the delay of decompression than CPUs. This makes it possible to exploit compressed L1 data caches, boost performance of GPGPUs. To offset the power overhead of a compressed cache, we use opportunities provided by cache compression to reduce dynamic, static power of the compressed cache. Our evaluation using a set of GPGPU benchmark suites shows that compression improves performance up to 20% with marginal impact on power.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
