included directly into the executable program.


1 templon 1462 # 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.
