What does "elastic" mean?
●
●
●
Computational resources can be added or removed at any time. Running computations benefit from added resources automatically. Computations on de-allocated resources are rescheduled automatically.
Why Elastic?
●
Bursty/intermittent computational workloads
●
Periodic resource availability
●
Resource contention and dynamic reallocation
doRedis Workers
Components
Redis Server Interactive R Session or Main Program
Toplogy The components can: ●
all be on a single computer
●
all be on separate computers
●
a mix of the above
●
connected by intra- or inter-networks (deparmental network, EC2, Azure, etc. )
doRedis and EC2 Ready to roll AMI available. Linux magic is in the redis-worker-installer.sh
file distributed with the package (a generic doRedis service for any LSB system). Windows version also available from https://github.com/bwlewis/doRedisWindowsService.
EC2 Example I: Start doRedis workers

Launch one new instance--this can serve as the Redis host and as a worker node. Obtain the IP address of the new instance. Additional instances may be specified at any time by supplying EC2 user-data: host: queue: port:
