Notes de l'éditeur
- Intro Sr. Tech. Architect Charged with ensuring researchers have the “Infrastructure of the Future” Also ensure today's architecture is deployed properly and yesterday's architecture doesn't collapse... OpenStack running just over 1yr fits in as “tomorrow” (between today & future)
- Approx 50 groups in diverse areas Robotics Machine Learning Biomedical Computer Architecture Etc... All solving different problems using different methods Highly Complex Highly Diverse Incredibly Open Environment
- This one Is just as read about 30sec on what we setup
- Again just 30sec on recent changes
- Significant change in use since switching to over commit, though we rarely reach 2:1 on any node and are very nearly 1:1 over all (have seen peaks at 3:1) Larger multicore instance types and longer runtimes Pre over commit: Avg runtime 3:45 Avg vcpu 1.8 Post over commit: Avg runtime 39:20 Avg vcpu 4.2 It is not clear if this is causal...
- Alfa: Scalable evolutionary algorithms, machine learning and frameworks for knowledge mining, prediction, analytics and optimization.
- TREC-KBA: the MIT team organizing the 2013 Text Retrieval Conference's Knowledge Base Acceleration competition which seeks to help humans expand knowledge bases like Wikipedia by automatically recommending edits based on incoming content streams. This open evaluation measures an automatic system's ability to filter a large stream of text for new knowledge about entities.
- Ubik(sanchez): HW Simulation Wazzit?- simulated ~1 quadrillion instructions total, and at its peak openstack doubled to tripled the capacity Ubik proposes new hardware and software techniques to achieve systems that provide very strict quality of service guarantees for latency-critical workloads, and high throughput for batch workloads. The main motivation is that datacenters burn terawatt-hours, but servers, which make up the buk of datacenter power, are run at 10-15% of capacity to guarantee QoS for critical services. At the same time, datacenters have a lot of non-critical computing (e.g., MapReduce, overcommitted openstack VMs, etc.). In Ubik, we're developing a number of techniques that enable colocating both types of compute in the same system, sharing resources between batch and latency-critical workloads to achieve maximum utilization of CPU, memory, etc, but safely protecting latency-critical workloads from any noticeably degradation.
- NMS: used the cluster to host a contest for students in 6.829 (MIT's graduate networking class) to develop the best congestion control algorithms, by running the students' algorithms on pre-recorded traces of cellular networks. Also using it for heavy computation, running big machine learning problems to try to get computers to design new congestion control algorithms..
- LIS: Learning & Inteligent Systems conduct interdisciplinary research aimed at discovering the principles underlying the design of artificially intelligent robots.

- Julia: Julia is a VHLLs or very high level languages for parallel computing and now an MIT Licensed opensource project, this is the group at MIT that originally developed it https://ijulia.csail.mit.edu:8000 Cert protected frontend Alan's apaprently using this in 18.06 & possibly other classes http://web.mit.edu/18.06/www
- NMS – intelligent placement of VMs to reduce network congestion in the data center Scaling Note Bene for use with EdX (http://nb.mit.edu) and DetectMe new project similar to http://labelme.csail.mit.edu Consolidation isn't “exciting” but is a metric of stability and manageability OCPS (bit of a play on OLPC )idea has been around longer than our cloud, in this case each lab member would get a moderate quota allocation independent of any particular project just to hack around and do cool stuff. Factors preventing some users from taking advantage, need to access low level hardware, special coprocessing requirements. Cloud Desktops old idea coming round again thin client accessible from anywhere, suggestion from community testing various implementations. Will it be useful? Don't know...
