- from last week: I had to evaluate if fogify is good to experiment with cassandra
results
- ran ping and iperf in fogify topology to validate the latency and bandwidth
- results seem reasonable within the constraints specified by the topology model
discussion:
- go on with fogify and go ahead with cassandra and pathstore deployment
- goal for SEC is an initial evaluation of Cassandra and Pathstore
- we need to find reasonable topologies
- understand a good topology for cassandra/pathstore experiments
- deploy cassandra on docker/fogify
- discussion about individual project for Tom, validate fogify and potentially port to kubernetes
what I'm doing now:
- stuck on cassandra multinode docker deployment
- stuck on fogify deployment of infra
- native cassandra benchmark
- fogify benchmark for cassandra
- docker benchmark on fogify
- update on fogify demo and network capabilities
- presentation on fogify capabilities. Looks promising to emulate all the characteristics that are needed for now
- potential master thesis ideas: support for mobility of end nodes, migration from docker to cgroups
- Q: how many containers does our cluster support?
- decision on rejected paper draft -> go over the reviews, need to substantiate the programmability aspect.
- docker deployment to test latency, bandwidth and drop rate compliance, does fogify match the expected behavior?
- make revision plan for hotstorage for position paper, address the comments from the reviewers
- update on fogify state of things
- solved missing image so now I can deploy barebone fogify controllers, but still not deploy an application scenario
- problem at the moment is that they treat and deploy the application and infrastructure in a coupled way, whereas I would find it more convenient to deploy them separately
roadmap:
- finish taxi demo
- identify network capabilities in fogify, can it support mobility scenarios, network trace emulations, degradation of quality of signal as user moves, nodes joining and leaving
- deploy empty docker images on fogify, decouple infrastructure from application
- cassandra on docker (off fogify)
- YCSB experiment on the cluster, plot the results and understand how the latency behaves and if it matches with the cluster specs
- cassandra on docker (on fogify)
- evaluate cassandra at the edge
- Create a couple of slides with fogify infrastructure overview and functionality
- run demo example for the taxi app
- (hopefully) run cassandra example on docker
With Lin:
- talked about joining the HPDC reading group Sys4ML (FYI)
- discussed BSc thesis topic on in-network computing
- missing edge platform, need to build a system to deploy nodes/sensors and emulate different network conditions
- need to do paper reading for background and foundational papers for storage and networking
- create wiki page for papers to dump
- final review and work to submit the edgesys paper
- skipped meeting due to ACE seminar
