Abstract

fetched live from OpenAlex

Neste trabalho foram estudadas diferentes políticas de escalonamento de processos em um pequeno cluster de computadores dedicado a simulações de modelos biológicos. Para isto o perfil típico de carga de trabalho neste cluster dedicado foi reproduzido artificialmente, o qual leva em conta três diferentes tipos de processos: sequenciais leves, sequenciais pesados e processos paralelos pesados baseados na biblioteca MPI. O cluster de computadores utilizado é baseado em Linux e foi montado com o pacote NPACI Rocks. Para o escalonamento de processos foi utilizado o Sun Grid Engine (SGE), que acompanha o NPACI Rocks. O SGE oferece integração com o MPI e permite a criação de filas de processos com características distintas. Foi realizado um estudo comparativo entre o comportamento de diferentes políticas de escalonamento submetidas à carga de trabalho em questão. As métricas adotadas e os objetivos desejados foram os de redução do tempo médio de execução dos processos, aumento da taxa média de processos executados e redução do tempo ocioso dos processadores do cluster. Esta avaliação nos permitiu estabelecer uma forma eficiente para gerenciar os recursos computacionais deste cluster de computadores dedicado.

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.
