Abstract

fetched live from OpenAlex

MPI-NP II is a network processor based message manager for MPI. The objectives of MPI-NP II were to reduce host processing and to make use of the processor on the network interface board to do message scheduling and message matching. The design of MPI-NP II is based on microchannels and message rendezvous. MPI-NP II implements MPI nonblocking communication as asynchronous communication and is able to overlap computation with communication. We introduce the concept of k.safe programs to guarantee message delivery based on the available envelope resources independent of the message size. We achieve these benefits without unduly burdening the NIC processor. We obtain a latency of 22 microseconds and a bandwidth of 92 MB/s, which is comparable to other Myrinet MPI implementations that perform MPI message management on the host.

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.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
