Abstract
Grid computing enables resources in different administrative domains to be shared. Researchers are able to collaborate more easily and can gain access to more computing power, enabling more studies to be run and larger problems to be considered. A common middleware employed by grid projects is the Globus Toolkit. Recently, a new version of the Globus Toolkit (GT4), based on standards that build on Web Services, has been released. However, most grid projects using the Globus Toolkit still employ GT2. This paper presents an approach for running molecular dynamics simulations in a mixed GT2/GT4 grid environment. Simulations are automatically checkpointed and migrated between sites as needed, increasing fault tolerance should a site fail. Users do not need to manually discover what resources are available and do not need to learn the potentially different approaches for submitting jobs at different sites. All jobs are submitted to a metascheduler which handles the site specific details. Simulations have been successfully run in a grid environment comprised of resources from across Canada, including resources from the Grid Research Centre at the University of Calgary, WestGrid and ACEnet.

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
