Change the design: (capacity per queue) => (capacity per broker)

Support enqueue operation via Python scripts.

Example: Redeis
RDB (periodic sanapshot) or AOF (journaling)

Example: Message Queues
Write on disk upon receiveing the message
Flush periodially for transient messages

Using permissions

Linux - cgroups, AppArmor
OSX - sandbox-exec
Windows

• (Windows Sandbox in Win10 Preview is a different feature)
• sandbox in Google Chrome
• Job Objects
• SAFER

Allow users to specify broker address with domain names.

Goal: keep simple single-node interface

UI

Master

grass start
grass enqueue .. // enqueue to a local queue

Slave

grass start --master 1.2.3.4:5678 // fetch pending jobs from master, update queue availability to master
grass enqueue .. // enqueue a job to a local queue
grass enqueue ..--master .. // enqueue a job to a server

User

grass enqueue ..--master .. // enqueue a job to a server

Events

When a worker started

• fetch pending jobs (with ahead buffer size)
  (multiple workers may have a duplicated pending job)

When a slave finished a job

• Report 'complete' to the master.
• Master's dashboard shows 'completed (slave 1)'.
• Try fetch pending jobs
• Check if any pending job can be run (ask the master for atomic op)

When a server received a job

• (long connection with worker?) notify a worker of a job
• (If no long connection): ?

Secure tcp connections.

A distributed client shouldn't run arbitrary commands unless desired.

Useful for parameter searches like BayesOpt, which cannot spawn arbitrarily many concurrent experiments.
