Looping over graphs in igraph
...ion algorithms on a couple thousand
small graphs but don't know how to automate igraph looking at multiple
graphs described in a single csv file. My data look like something in ncol
format, but with an additional column that has an ID for which graph the
edge belongs in:
Graph ID | Vertex1 | Vertex2 | weight
1 | Alice | Bob | 2
1 | Alice | Chris | 1
1 | Alice | Jane | 2
1 | Bob | Jane | 2
1 | Chris | Jane | 3
2 | Alice | Tom | 2
2 | Alice | Kate | 1
2 | Kate | Tom | 3
2 | Tom | Mike | 2
so on and so forth for about 2000 graph IDs, each with about 20-40
vertices. I've tried usi...

matrix into vector with vertex names
Using Igraph, I create shortest paths, then convert the matrix into
three column vectors - "vertex1", "vertex2", "shortestpath" - as the
code below shows.
#code for generating shortest path matrix and creating a 3 columns
from an igraph graph object "y"
y_s<-shortest.paths(y, weights = NULL)
y_s <- melt(y_s)[melt(upper.tri(y_s))$value,] #Step 2: this is where
the trouble wit...

Converting edgelist to symmetric matrix
Hi,
I have network data in the form of a couple of edgelists containing weights in
the format "x,y,weight" whereby x represents row header and y represents column
header. All edgelists are based on links among 634 nodes and I need to convert
them into a 634*634 weighted matrix.
I searched for online help using possible keywords I know, but I could not find
a clue how to do this in

[SPAM] XCP 1.0beta and vastSky. What information I have gathered, what I did and how "far" I got with it.
...all this. I have one four node SuperMicro twin2 server (2026TT-HiBQRF) with
QDR InfiniBand (haven''t bought a switch or managed to get drivers for dom0''s
yet, so it''s gigabit ethernet for now). Each node is identical, containing:
1x Intel Xeon E5620, 12GB ddr3, 3x 60GB OCZ Vertex2 ssd and 3x 500 GB
Seagate Momentus 7200.4 SATA 2.5". No raid cards, just the onboard ICH10.
Networking configuration:
node A: hostname: super0nodeA ip: 192.168.10.210
node B: hostname: super0nodeB ip: 192.168.10.211

SAS/short stroking vs. SSDs for ZIL
Hi,
as I have learned from the discussion about which SSD to use as ZIL
drives, I stumbled across this article, that discusses short stroking
for increasing IOPs on SAS and SATA drives:
http://www.tomshardware.com/reviews/short-stroking-hdd,2157.html
Now, I am wondering if using a mirror of such 15k SAS drives would be a
good-enough fit for a ZIL on a zpool that is mainly used for file
