665.0. "Building base model process in loop" by COMICS::JOLLEYD () Tue Jan 28 1997 06:43

Hi all,


I'am now running Polycenter Capacity Planner V4.0-00
with MOTIF 1.2-4

I am trying to create a base model from the 'CPD' files
for 17-Jan-1997.

I have been able to create .MERG files from the source data
for a time window of 14:00 to 16:00, and those merge files
have been read in and the System Configuration/Network
diagram updated.

BUT.......!!

The process goes into compute loop when building model


Current image is ECP$PLAN.EXE;9

Building base model...please wait

Is this a problem with my data ?

How many classes do you have and how many subclasses?  How many of the 
classes are Closed type?

Jilly,

	Include below the extracts from the Class definition file
 	Number of classes = 30 , number of subclasses=10
 	Number of classes of closed type ?  ? none ?

To see the class type bring up a class in the class editor and look in the 
upper right at the Model Type field. (See Figure 6-4 in the PSCP User's 
Guide - Define Classes Dialog Box)

30 classes with 10 subclasses Yow!!!!  Do you REALLY need this many classes 
& subclasses for this particular modeling study????  I can't stress enough 
keeping your models as simple as possible for the particular modeling 
study.  IMHO, the tool works better on simplerer models.  While you can 
describe the work done on a system down to the nth degree (ie 30 classes & 
10 subclasses) are you going to do something in the modeling study with 
each and every one of these classes and subclasses??

I expect your problem will stem from a large number of your classes being 
closed type classes which causes exponential cpu resources to be consumed 
for each closed class.  Run this model on a 500mhz Alpha and it will 
probably complete in less than a week.
