Eventually I was able to create a profile, but I had to edit the
master Makefile. Under Linux the file:

  /usr/etc/swarm/Makefile.common

contains:

 ifeq ($(USE_EXTRALDFLAGS),)
 EXTRALDFLAGS =
 else
 EXTRALDFLAGS =
 endif             

which would seem to nix EXTRALDFLAGS.  This is common to 2.0 and 2.1, am I
missing something here?

I've not looked much at profiles before, so I've just put the top
of either below.  Both are missing the us/call data from the main
routines, how do I fix that?...

To me the strange part is the 2.1.1 profile shows a 3 second
cumulative time, but the execution took about a minute and a half, a
tcsh "time" output for the 2.1.1 run is
   94.110u 0.630s 1:44.05 91.0%    0+0k 0+0io 1899pf+0w      

and the 2.0 run,
   13.600u 0.220s 0:21.45 64.4%    0+0k 0+0io 1753pf+0w          

some of the missing time is in my editing a parameter, and clicking "start",
but not 90 seconds....    

Thanks, I appreciate any help you can offer...
