ServerKiln

See at a glance which GPU servers are training, how many GPUs are busy and what's offline, and get a push alert on your iPhone the moment training ends. ServerKiln is the iPhone companion to ServerKiln for Mac. The Mac app adds your servers and deploys a dedicated read-only key for iPhone on each one, synced through iCloud Keychain. The Mac app is free at serverkiln.littleor.cn.
