Did anyone succeed using profiling for PVM on an nCUBE?  We have an
nCUBE/2 and PVM 3.2 (BTW: has anyone a newer version?).  I've tried
several ways to profile some applications, but all failed.  First, I
set EXPROF_SWITCHES to 'x' or 'c' and ran my application (pvmd -D 2,
xnc -s -h 0 k2m2). It simply hangs after "finishing", i.e., I get the
output directly before the exit(0) statement in my program, but it
doesn't return. Same applies for compiling with '-p': the program hangs
at the end, and if I type CTRL-C I get:

Assertion failed: cell->caller!=(CallerCell*)0, file mon.c, line 643
*** Process 12 on node 0 faulted
*** Reason: bad address
Node    0; 1> where
start  [crt.s,?] () at 0xc

Any hints what to try next? I need some profiling data since a
program generated by a compiler (from a student) is about 50%
slower than a hand-made program...

Thanks in advance,

Claus Assmann
