Google's MapReduce programming modelserves for processing large data setsin a massively parallel manner. Wedeliver the first rigorous description of the modelincluding its advancementas Google's domain-specific languageSawzall. To this end, wereverse-engineer the seminal papers on MapReduce and Sawzall...

MapReduce:In 2004, Google shared the MapReduce programming model that simplifies data processing on large clusters. The Apache Hadoop project is an open source implementation of the MapReduce algorithm that was subsequently created by the community. BigTable:In 2006, Google introduced the BigTable d...

This Monday I published my article on MapReduce for integer factorization in arXiv. The article is essentially the same that can be downloaded in the research section of this site. So if you have already checked it out, you won't find anything new. However I am very excited because it ...

I spend a lot of time programming in JAX. I helped developDrJAX, a library for building MapReduce-style algorithms in JAX, which we use to speed up DiLoCo training. I also developedDataset Grouper, a library for creating fast group-structured dataset pipelines, which can greatly accelerate ...
2、You design and implement robust data driven algorithms on a massively parallel platform (i.e. Hadoop, HBase, MapReduce, AWS). 3、You combine signal processing, machine learning and knowledge based methods in order to realize i.e. anomaly detection, fault classification, diagnosis and prognosi...
