included directly into the executable program.


1 # This is dot2term, a program that converts graphs expressed in 'dot'
2 # format, into the 'term representation' that can be handled by
3 # uDrawGraph.
4 #
5 # WHY
6 #
7 # The quattor tool 'panc-call-tree.pl' can output the include tree of a
8 # quattor machine profile; the supported formats are 'dot' and
9 # 'hypergraph'. 'dot' can be read by Graphviz [1] and 'hypergraph' can
10 # be read by Hypergraph [2]. Neither of these tools allow for easy
11 # navigation of the graphs, nor (especially important to me) hiding
12 # various pieces of the subgraph, in order to be able to view the
13 # interesting part at a reasonable scale. The uDrawGraph [3] program
14 # does allow such manipulations of the displayed graphs.
15 #
16 # WHAT
17 #
18 # * run the pan compiler on your favorite template with logging mode on. At Nikhef
19 # the relevant command is
20 # makexprof -l call -f <cluster> <hostname>
21 #
22 # * run panc-call-tree.pl; at Nikhef the relevant command is
23 # panc-call-tree.pl $L/build/log/panc.log
24 # This will yield a file <hostname>.dot in the current working directory
25 #
26 # * run dot2term
27 # dot2term <hostname>.dot
28 # This will yield a filename <hostname>.udg if the input file ended in '.dot';
29 # otherwise the output file will be called <inputfilename>.udg
30 #
31 # LIMITATIONS
32 #
33 # The 'dot' language includes many features; I only dealt with converting those encountered
34 # in the output of panc-call-tree.pl. There are probably many dot files which cannot be
35 # converted with this tool.
