IBM 3090 Model 600J compared with modern desktop PC's.
Sternbach, William
Jun 15, 2007
Hi,
I hope its ok if I share some interesting research I did on the capacity
and specs of IBM 3090 Model 600J computer
which I had been impressed by in the early 1990's as being able to
handle 700 TSO online users doing Cobol compiles,
multiple 24/7 CICS regions, huge numbers of concurrently running Cobol
batch programs doing massive I/O during
nightly batch cycles, etc.
I came to some surprising conclusions after doing this research,
specifically at how slow and low capacity
this high end mainframe 3090 600J computer really was compared with
today's desktop PC's.
Please see: http://ukcc.uky.edu/~ukccinfo/ibm3090.html (for the specs of
model installed in Kentucky).
Please see: http://freespace.virgin.net/roy.longbottom/mips.htm (which
lists the 600J's CPU speed as only 69 Mhz each).
I hope you will forgive my use of Mhz and Ram (as I know they're not
directly comparible).
IBM 3090 600J had: 6 CPU's running at 69 Mhz each, 200 GB total hard
disk space, 1.5 GB Ram.
My Desktop PC has: Intel Core 2 Duo 2,666 Mhz, 1,000 GB total hard disk
space, 4 GB Ram.
Then, I researched a long lived Fortran benchmark that actually ran on a
wide range of computers (see below):
Mdbnch - Molecular Chemistry benchmark:
http://www.fisica.uniud.it/~ercolessi/Mdbnch/info.html
and the results are interesting. To summarize, my desktop PC ran this
benchmark
in less than 1 second, while the IBM 3090 600J ran this benchmark in 76
seconds.
The Cray computer ran it in: 15 seconds, and some old Digital Vaxes
took: 8,000 seconds.

Hi,
I believe the reason we don't have 700 users connecting to our desktop
PC
is more a function of the high overhead of modern Windows Operating
Systems.
Desktop PC's today are thousands of times faster than the original IBM
PC,
yet the response time today is similar to the response time running Dos
or Windows 3.1
on the early desktop PC's. The culprit is the high overhead of Windows
Operating Systems.
The question really is: If IBM had made a version of MVS which ran on
the Intel x86
architecture, could a modern fast desktop PC handle the load of an IBM
mainframe.
Perhaps it would be a question of throughput.
I wrote a benchmark program in C (which I could email you if you're
interested),
which writes 10 Million 100 byte records to the hard disk, and then
reads them back.
On my Intel Core 2 Duo E6700, writing 10 Million 100 byte records only
took the computer
2 and a half seconds to do, and only a half second to read the 10
Million 100 byte records.
So, potentially, the throughput on desktop PCs is there.
