Hello,
My name is Federico Sacerdoti, and I am a part of the Rocks cluster team
here at SDSC in San Diego. I will be working on ganglia more or less
full time for a few months at least, helping Matt out with the web page
and adding some metrics. Our big project here is the NPACI Rocks
clustering software, which (attempts) to make building large scientific
clusters easy.
We saw the genius of Ganglia early on, and helped test Massie's earliest
versions of the software. I just met Matt at Berkeley yesterday, and
despite a big night on wednesday and a sunburn, he was a gracious host
and we had a great time. We talked about lots of ganglia, including a
new TTL tag for metrics, process reporting, disk used/free metric, and a
dynamic time-threshold control.
Initially, I will submit patches for a new web-page, and some graph
domain changes for the gmetad-webfrontend. A small cluster with the new
changes can be seen at http://fossil.sdsc.edu/ganglia/. Choose a string
type metric such as os_name to see how they are not graphed anymore.
Also notice that all metric graphs in cluster_view have synchronized
domains over the entire graph history, not just the current value. The
Compact View page is another, physically oriented, view of the cluster
using ganglia data. I will be adding a new LOCATION=(x,y,z) attribute to
the HOST tag in the XML output to help support this page, and give an
easy way of finding where a node is in the cluster by rack, rank, and
plane.
I have been reading the posts to this list for a few weeks, and I would
like to say I am excited to work in a community with such talented
programmers. I look forward to our collaboration together.
Federico
PS I would also like to add a LATLONG attribute to the CLUSTER tag to
enable cool red dots on a globe PNG, showing where each cluster sits
based on GPS coordinates.
