متن کاملDeath of Dolly marks cloning milestone
Dolly the cloned sheep marked both an icon of scientific possibility and a potential ethical nightmare. Researchers in related fields of stem cell research need to learn the lessons and the right vocabulary if they are to make progress in their fields.
متن کاملWhy Let Resources Idle? Aggressive Cloning of Jobs with Dolly
Despite prior research on outlier mitigation, our analysis of jobs from the Facebook cluster shows that outliers still occur, especially in small jobs. Small jobs are particularly sensitive to long-running outlier tasks because of their interactive nature. Outlier mitigation strategies rely on comparing different tasks of the same job and launching speculative copies for the slower tasks. Howev...
