Links of the day 20/10/2015: velocity conf, networking trends and cloud guide for HPC

• Velocity 2015 : speakers slides , lots of very good talks, particularly the sampling strategy for large scale monitoring and breaking stuff to make them more reliable.
• Cloud HPC guide : when you want your workload doesn't fit the enterprise definition.
• HPC networking trends : while the trend is always for bigger network the interesting aspect is the focus also on improving the MTTI as it currently takes days to recover from failure.

Links of the day 15/10/2015: Paxos , NVM for In-memory DB , Workload characterization Conference

• EPaxos, transactions and the next 700 Paxos systems : well distributed consensus will always be a highly discussed topic and wheel will be reinvented many time because not everybody like the size of the. 
• Energy-Efficient In-Memory Data Stores onHybrid Memory Hierarchies : propose code instrumentation in order to identify the best object placement for performance/power efficiency. Nice idea however lack of practicality for production environment. Also it assume a pretty stable behavior of the system.
• IISWC-2015 : 2015 IEEE International Symposium on Workload Characterization

Links of the day 14/10/2015: Kernel Bypass, stateful services, erasure codes benchmark

• Streaming video 10Gb and beyond : well seems everybody is bypassing the kernel nowadays.
• Building Scalable Stateful Services : Age old cycle - state - no state - etc.. 
• Benchmark comparisons of erasure codes : pick carefully , but not all are equal. Again there is no one size fit all.

Links of the day 13/10/2015: #intel cache partitioning, #AWS dynamodb crash aftermath, SOPS15

• Intel cache partitioning : why Intel added cache partitioning, the feature is really useful in order to avoid cache pollution and noisy neighbor effect in virtual environment. Until there is an automated way to provision the configuration (autonuma style maybe). It will remain niche. Too bad this is badly needed as the number of cores to cache ratio keep increasing. 
• Irreversible Failures : Lessons from the AWS DynamoDB Outage, and why you should always be prepared for white/gray/black swan events. Make your system ductile not brittle.. 
• SOPS 2015 : interesting pick from microsoft research : ironfleet distributed system validation, and distributed transaction. From Intel we have the virtual cpu validation

Links of the day 12/10/2015: virtual cores, nvdimm for qemu and driver queue splitting

• VISC : update on the virtual core technology by soft machine. Interesting concept, however like the Itanium, really hard to pull off as it requires a specific combination of software and hardware to work. Lets see if they fare better than Intel in that domain.
• Queue splitting: want to use DPDK for some traffic and the rest go through the standard stack? checkout the bifurcated drivers!
• NVDIMM and persistent memory in QEMU : cool talk about persistent memory tech for virtualization. This open up a whole new realm of possibility.

Links of the day 07/10/2015 : consensus, transaction and correctness

• Consensus in the wild : lot of way to achieve consensus out there but which one is the most efficient for your requirements. Answer : it depends and we have no consensus.
• IronFleet: Tool for proving corectness of practical distributed systems using TLA-style state-machine refinement and Hoare-logic verification. 
• AtlasDB : Transactional Distributed Database layer on top of K/V store.

Links of the day 06/10/2015 : the long road to quantum computing , collaboration tool, and cloud scheduling

• ORCHESTRA : open source system to orchestrate teams of experts and machines on complex projects.
• Expensive Road Ahead For Quantum Computing : well nobody said it was going to be easy.
• Cloud Computing Resource Scheduling and a Survey of Its Evolutionary Methods : A good insight in evolutionary scheduling method for cloud or other similar problem.
