Hi Adam:

(Found the .ppt file, duh, sorry about that, not looking properly.)

I have a question. we would like to try to do model checking to see if 
we can actually generate 1000 different *expected* mean end to end times 
for appstring A in GT-4. Towards this end, where can we find the 1000 
allocations that you actually used in these 1000 tests? On the wiki I 
can only find the 300 allocations that CMU provided for GT-4. (I believe 
you started with these 300 and did perturbations to get 1000 runs, 
right? It would be good if all the 1000 allocations are on the wiki and 
a table showing:

Allocation_#   CUTS_Measured_Mean_E2E_time      Model_Predicted_E2E_Time


This will be 3 columns in all.  (As you know we have been focusing on 
producing such 3 columns using not the mean but the worst case time, a 
problem that is much tougher due to jitter in these large systems.) But 
for now let us concentrate on the mean performance in  time shared 
system where all priorities are equal. (Of course we don't quite know 
the time shared quanta, or do we? This could have some impact on column 3.)

IF we start with the CMU's 300 allocations of GT-4 and generate 3rd 
column of data for each of these 300 allocations may be we can generate 
a table of 300 rows for now and make a graphic for possible use on 24th.

PS I believe your processor pool consists of identical machines, right? 
Thus, no surprise that processor permutation did not make any 
difference, though good to see it.)
