Misters, FYI : incubator.apache.org/tashi The Tashi project aims to build a software infrastructure for cloud computing on massive internet-scale datasets (what we call Big Data). The idea is to build a cluster management system that enables the Big Data that are stored in a cluster/data center to be accessed, shared, manipulated, and computed on by remote users in a convenient, efficient, and safe manner. To quote : docs.google.com/viewer?url=https://opencirrus.org/system/files/Tashi-OpenCirrus-Presentation-v2.ppt Where are we today? (cont) ? Our deployment of Tashi has managed 100s of VMs across 10s of hosts ? Used for day-to-day work by developers ? Light use by others ? Biggest benchmark ? Performed a ground motion simulation (HPC MPI job) using 240 VMs Best Regards, Guillaume FORTAINE
