Here are a few questions :
==========================
What exactly are specint and specfloat ?
How can you compare spec to mips ?
For my own system, should I look at specint or specfloat ?
And here is all the story :
===========================
I am now working on choosing a target computer for a airport management system.
We already made simulation of the system on sparc 10/30 and on Bull DPX2/360 Bi-processor (a french computer with two 25Mhz 68040).
The best of these is the Sparc 10/30 but it is not enought :
CPU load is about 80 % and times must be devided by two.
So we need to choose another machine with about twice the power of the sparc 10/30.
We looked at Sparc 10/52 and at RS6000.
The sun should be OK but we are wondering about disponibility and porting on Solaris 2 (which seems to be the only system for that machine).
RS6000's seems to be good for specfloat compared to the sparc 10/30, but specints are not so good.
We can also get a DPX2/380 with 4 processors (33 Mhz 68040) : 100 Mips (!?)
So the point is : does my appplication use a lot of specints or a lot of specfloat ?
The application looks like that :
=================================
2 layers : Hard Core and User Layer.
The hard core is composed of about 10 servers processes for processing and storage managements (Processing is basically consistance management and checking, only few calculations).
The User Layer manages interaction with users ; there is one process for each screen (vt100) which offers menus, lists of items, forms filling and so on...
There are a lot of message exchanges between all these process, implemented with Unix messages queues, files, and signals for asynchroneous messages.
CPU repartition is the following :
Oracle : 26 %
Hard Core : 20 %
User Layer : 49 % (38 processes)
....
Here it is...
Christophe.
PS : any informations/experiences on sparc 10/52 or RS6000's are welcome.
