Rosella: A Self-Driving Distributed Scheduler for Heterogeneous Clusters [article]

Qiong Wu, Zhenming Liu
2021 arXiv   pre-print
We present Rosella, a new self-driving, distributed approach for task scheduling in heterogeneous clusters.  ...  We evaluate Rosella with a variety of workloads on a 32-node AWS cluster. Experimental results show that Rosella significantly reduces task response time, and adapts to environment changes quickly.  ...  CONCLUSION This paper introduces Rosella, a scalable self-driving scheduler for for use in homogeneous and volatile environments (i.e., the processing powers of backend servers are different and evolve  ...

Reproduction and maternal health care among young women in Kenya: geographic and socio-economic determinants

Carla <1983> Pezzulo, Rosella Rettaroli
The analysis of factors associated with maternal healthcare-seeking behavior for young women in Kenya was investigated using multilevel models.  ...  There are differences at the women's level on the probability of receiving antenatal care and delivering in a healthcare facility instead of at home.  ...  If the first visit is made during the third month of pregnancy, this schedule translates to a total of about 12 or 13 visits.  ...
