Abstract
iWARP represents the leading edge of high performance Ethernet technologies. By utilizing an asynchronous communication model, iWARP brings the advantages of OS bypass and RDMA technology to Ethernet. The current specification of iWARP is only defined over connection-oriented transports such as TCP. The memory requirements of many connections along with TCP's flow and reliability controls lead to scalability and performance issues for large-scale HPC and datacenter applications. In this research, we propose guidelines to extend iWARP over datagrams to provide better scalability and performance. While the proposed extension is designed for use in both HPC and datacenters, the emphasis of this paper is on HPC applications. We present our software implementation of datagram-iWARP over UDP and MPI over datagram-iWARP. Our microbenchmark and MPI application results show performance and memory usage benefits for MPI applications, promoting the use of datagram-iWARP for large-scale HPC applications.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
