Evaluation of ConnectX Virtual Protocol Interconnect for Data Centers
Bibliographic record
Abstract
With the emergence of new technologies such as Virtual Protocol Interconnect (VPI) for the modern data center, the separation between commodity networking technology and high-performance interconnects is shrinking. With VPI, a single network adapter on a data center server can easily be configured to use one port to interface with Ethernet traffic and another port to interface with high-bandwidth, low-latency InfiniBand technology. In this paper, we evaluate ConnectX VPI using microbenchmarks as well as real traces from a three-tier data center architecture. We find that with VPI each network segment in the data center can use the most optimal configuration (whether InfiniBand or Ethernet) without having to fall back to the lowest common denominator, as is currently the case. Our results show a maximum 26.7% increase in bandwidth, a 54.5% reduction in latency, and a 5% increase in real data center throughput.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
