Webatomicity (“consistency”) they want GraphLab runtime to provide: this determines amount of available parallelism -“Full consistency”: implementation ensures no other execution reads or writes to data in scope of v when vertex program for v is running. -“Edge consistency”: no other execution reads or writes any data in v or in edges WebGraphLab is a large-scale graph-parallel distributed analytics engine Some Characteristics: In-Memory (opposite to MapReduce and similar to Pregel) High scalability Automatic …
WebWhy do we need GraphLab? Machine Learning and Data Mining (MLDM) problems increasingly need systems that can execute MLDM algorithms in parallel on large clusters. Implementing MDLM algorithms in parallel on current systems like Hadoop and MPI can be both prohibitively complex and costly.
