Thanks, I will look into this.

The dependence on the X11 libraries was meant to be removed from the 
Makefile, as it's not needed unless you are using the interactive graph 
drawing feature. I will check into this.

OK, I will check into it.

This is normal. It's because PVM has not been maintained and uses 
deprecated library calls.

symphony_m_tm is the primary executable. the "_m_tm" part means that the 
master and treemanager modules are part of that particular executable. 
Running "symphony_m_tm" as you would "symphony" is the sequential case 
should work fine. (Note: I just changed the Makefile slightly so that 
you may also see "_cp" (stands for "cut pool") on the end of the 
executable name, but you should always just run the one that has "_m" in 
the name).

First, start PVM, then run symphony_m_tm as usual. Make sure you 
symphony_lp_cg is in your PVM executable path. The easiest way is to put 
a soft link to it from ~/pvm3/bin/LINUX.

> b) how do I launch the sample application vrp with pvm ?

Set COMPILE_IN_LP = FALSE in the VRP Makefile and build as usual. You 
should get executable names like you do with SYMPHONY, except that they 
will start with "vrp" instead of "symphony." They can be run the same 
way as the sequential executable.

Getting the graph drawing module up and running will probably be 
nontrivial. The first step is to make the graph drawing executable with 
PVM enabled. With the COMM_PROTOCOL set to PVM, type "make dg." After 
that, you have to get IGD running with the tcl/tk libraries. It should 
still work in theory, but I haven't tried it for quite a while. I can 
try to help if you want to give it a go.
