GDP

The GDP version number has been bumped to 0.8.2. This is a patch release — there should be no major changes. However, a number of bugs were fixed, so people who use the GDP library and/or applications should update.

The GDP software on our servers has been updated and log purging and repair is complete. Everything should be back up now.

We attempted to get rid of what appeared to be abandoned logs (over 25,000 of them!). If we accidentally purged your favorite log please let us know and we will restore it.

On Friday 9/8 the GDP servers (and hence all access to logs) will be down for maintenance. We'll make it as early as possible (probably around 7:00am). It's hard to know how long it will be down, but it will be somewhere in the range of 1–2 hours.

The gdp_gcl_unsubscribe method, as defined in source:doc/gdp-programmatic-api.html, has been implemented. Since this a functionality change, the version number on the GDP library has been bumped to 0.8.0. The Berkeley-based GDP log servers have been updated.

The network connections to gdp-01 and gdp-03 log servers will be down on Tuesday 6/13 starting at 10:00am to re-route the cables due to construction work in 490 Cory. The outage should be brief.

The GDP source code is now open for public access If you have an account on repo.eecs.berkeley.edu and you have uploaded your ssh key, you can use:

git clone git://repo.eecs.berkeley.edu/projects/swarmlab/gdp.git

For anonymous access, use:

git clone https://repo.eecs.berkeley.edu/git-anon/projects/swarmlab/gdp.git

The EECS department will be doing a full power shutdown on December 22 from 7:00am to 11:00pm (Pacific Time, 15:00 12/22 to 07:00 12/23 UTC) to perform fire and emergency power testing in the server rooms. This will include the code repository (repo.eecs.berkeley.edu) where the GDP code is hosted, and the EECS network, which will mean that the GDP servers will not be accessible. Please plan accordingly.

See https://iris.eecs.berkeley.edu/news/16954-eecs-full-network-and-service for details and status updates.

The construction crew has finished re-routing the network cabling. It's likely that we will have another outage next week to re-route the power, but we don't yet know when that will be or how long it will take.

The construction crew has decided to postpone re-routing the power until next week, so today we will just have two short disruptions while we move the data cable. These should be no longer than a couple of minutes each.

Due to construction in the Swarm Lab, we are going to have to disconnect the power and network to gdp-01 and gdp-03. All logs and routers on those servers will be unavailable until the power and network are re-routed (probably a couple of hours). We still don't know exactly when the machines will be shut down, but it will not happen until the construction crew figures out the least disruptive course of action.
