Lulu Zhu <cz67@cornell.edu>

Team: Zhichun Liang, Peter Borbat, and Lulu ZhuOliver Habicht.

Goal

Run humongous jobs, and run them hundreds of times. Expect that having own equipment is most cost-effective, but reality-check against other options such as CAC's RedCloud service (not mutually exclusive).

Project status

Must work out some technology

As of 5/1/13: Lulu is working on Linux/ CU AD integration in preparation for Eldor's move to CRCF.

To buy us time, move Eldor under CRCF's management for ~6 months. This requires a new OS and file system service to replace CCMR's AFS.

Note

Required changes to Eldor are linked to moving off of CCMR's AFS. Hence the move from AFS will be being explained here, as a sub-project to the Eldor move project.

Steps and draft timeline

Ensure CIFS (replacement to AFS) is working for Liang. Includes testing permissions, including writes.

Draft start date:  May 24

Duration: About two days.

Make sure everyone has alternative ways to access AFS.

Turn off Eldor

Tentative date: May 29.

Turn on Eldor, connected to CIFS

Tentative date: About a week after Eldor is turned off.

Ensure Eldor is working for Liang. Includes testing ssh, software.

Draft start date: June 6.

Duration: About two days.

Move Liang's data from AFS to CIFS. Ensure CIFS is working for Liang.

Draft start date: June 10.

Duration: About two days.

Move other users' data from AFS to CIFS one by one.

Draft start date: Week of June 10. As CIFS added for user and data moved to CIFS, turn off AFS for that user.

Duration: About one-two weeks. Do quickly to reduce overlap of some folks on AFS and some folks on CIFS.

Turn off AFS (waiting this late allows us to roll-back, if Eldor must be reverted)

Tentative date: Do soon after all accounts have been successfully moved to CIFS and have thus been turned off from AFS.

Status

Must identify all current users of Eldor
