JustFit runs a 27‑billion‑parameter Qwen3.8 model on a 24 GiB MacBook, extending single‑request context to 212 k tokens (6.93× baseline) and achieving 19.11 tokens/s on a 32K‑input test.

  • 24 GiB M4 Pro MacBook
  • 212,992 context positions (6.93×)
  • 19.11 tokens/s on 32K‑64 probe

JustFit integrates three mechanisms—KVExec for compressed key‑value storage, PhaseSwap for component residency, and StateTrans for state‑preserving transitions—independent of model quantization. In tests, three runs processed 196,608 input tokens and 16,384 output tokens. A two‑request scenario kept 229,376 positions in total. These techniques enable near‑full‑model execution on limited‑memory laptops.

CCL is an LLM distillation method that iteratively calibrates the teacher using source feedback and trains the student on target questions, using token‑level branching without target‑domain rewards.

The method targets covariate‑shift scenarios where teacher reliability on target queries is unknown and no reward signal exists. By calibrating the teacher on source‑domain feedback, the student learns from a less biased teacher on target data. The token‑level branching lets the student influence subsequent calibrations, forming a feedback loop. The authors prove a bound on the student’s expected average KL divergence.

Fuse is a multi‑agent simulation that gives LLM assistants verifiable social‑reasoning tasks by embedding a hidden‑motive target agent, validated with 24 k human annotations and used to benchmark 12 models.

  • 24k human annotations
  • 12 LLMs evaluated

Fuse constructs a hidden‑motive target agent whose intentions are known to the simulation, providing ground truth for evaluation. Users interact with the target through other agents before consulting the LLM assistant, mirroring real‑world social advice settings. A human study with 24 k annotations confirmed the simulation’s fidelity. Applying Fuse to 12 LLMs revealed systematic differences in motive inference accuracy.

The project builds a highly accurate clock using a tiny microcontroller that decodes the DCF77 77.5 kHz time signal broadcast across Europe.

  • 77.5 kHz DCF77 signal

PostgreSQL now averages about 50 commits per week, up from roughly 25 in 2010, with the number of active committers roughly doubling over the same period.

  • ~50 commits/week now
  • ~25 commits/week 2010
  • ~2x committers since 2010

The weekly figure smooths to a clearer monthly trend, though commit size and whether changes are features or fixes vary. The growth aligns with the rise in active contributors, suggesting the development pace matches community expansion.

A patch series by Tao Cui adds BPF programmability to the blk‑iocost I/O controller, enabling custom cost decisions for block I/O scheduling on SSDs.

blk‑iocost was originally built for solid‑state drives to balance fairness and high throughput. By loading BPF programs, administrators can tailor cost functions without altering the core scheduler, offering flexible policy experimentation.

DeepShare scheduler raises average GPU utilization to 70.58%—a 29.5% gain over the best non‑intrusive sharing baseline—and cuts average queueing delay by 46% in trace‑driven tests on 23 k Venus jobs and 3.2 k internal jobs.

  • 70.58% GPU utilization
  • 29.5% improvement over baseline
  • 46% queueing delay reduction

DeepShare uses a continuous tenant‑assurance signal to coordinate elastic quota borrowing, runtime prediction, cost‑aware preemption, and interference‑aware MPS colocation. The signal also decides when to reclaim borrowed capacity or tighten sharing, improving overall cluster efficiency.

The Horizon Europe DS2 project delivers a layered framework that lets DigiAgro and AgroScience data spaces securely exchange farm IoT measurements, satellite images, and weather metrics while preserving farmer sovereignty.

The methodology follows a reference architecture where each layer hosts independent modules for data ingestion, transformation, and access control. This automated ecosystem addresses IoT data fragmentation and enables transparent, sovereign data sharing across agricultural sectors.

The paper proposes Nested BSP, a recursive extension of classic BSP, and a Nested Parallel von Neumann Architecture with a Unified Bus interconnect to coordinate million‑scale processor arrays under a single programming model.

Large‑scale AI workloads now depend on orchestrating many processors rather than a single powerful core. Nested BSP repeats the work‑barrier‑exchange‑aggregate cycle at each hierarchical layer, while the proposed architecture treats every node as a peer, simplifying massive parallel coordination.

The proposed γOPD method adds discounted temporal credit to on‑policy distillation, achieving horizon‑independent variance while preserving outcome feedback via a reward‑compatible bounded mixing mechanism.

γOPD interprets token‑level OPD as a temporal approximation of sequence‑level reverse‑KL gradients, balancing long‑horizon supervision with optimization stability. The RBM component blends verifiable reward signals with model predictions to maintain training fidelity.

The paper shows existing Byzantine reliable broadcast schemes cannot enforce causal ordering because Byzantine nodes can falsify dependency information, highlighting a gap in current protocols.

Causal order traditionally relies on the happened‑before relation, which assumes honest reporting of events. Under Byzantine faults, processes can lie, omit, or forge dependencies, making causal guarantees indistinguishable from correct behavior without additional safeguards.
