RE: Stress Testing Hyperion under Windows Server, Updated

Hercules390 - General mailing list
After all the discussion of z/OS benchmarks, I decided to see how a simple
change to the .CNF file would affect my Hyperion stress test numbers.  Per
the information previously pointed out by Fish, I increased my DEVTMAX value
from 8 to 16, giving me eight more device threads..  As before, I ran my ten
(10) full NBENCH Assemble, Link, and Go JOBS.  Absolutely nothing else has
changed, nothing whatsoever.  The average wall clock time per JOB is now
6.93 minutes.  That's a decrease of 1.40 minutes, or 16.80%.  That's a
significant number.  Here are my HERCGUI log numbers:

 

17:02:26.928 00000D8C HHC02272I From Sun Jan 29 17:02:26 2017 to Mon Jan 30
17:02:26 2017

17:02:26.928 00000D8C HHC02272I MIPS: 910.316468

17:02:26.928 00000D8C HHC02272I IO/s: 2900

17:02:26.928 00000D8C HHC02272I Current interval is 1440 minutes

 

The MIPS number went up by 98.168611, or 12.09%.  Again, that's significant.
But IOs per second decreased by 336 or 10.38%.

 

Again, absolutely nothing changed in my stress test except for doubling the
DEVTMAX value.  Who would have thought such a small change would have
produced such a significant performance increase?

 

In the near future I will be updating the operating system to Windows Server
2012 R2.  When everything is stable once more, I'll re-run my stress test.

Well, I updated the BIOS and chipset microcode on my Dell box to the latest
and greatest levels.  I then continued with my stress testing.  This time I
submitted ten copies of NBENCH (with unique JOB names of course).  Eight
immediately jumped into my free initiators and ran to completion.  As the
first two NBENCH jobs completed, the remaining two pending jobs jumped into
the free initiators.  All NBENCH jobs were full Assemble, link, and go
examples.  For those who aren't familiar with full NBENCH, each JOB consists
of 35,000+ lines of Assembler source, executes 43 program steps, and
produces 72,000+ lines of SYSOUT.  The average wall clock time per JOB was
8.33 minutes.

I decided this method of testing would maximize the mix of I/O and CPU usage
and give me a more realistic measurement of true machine performance.  Below
are my HercGui numbers.  The CPU number is slightly lower than before, but
now notice the I/O number.

12:06:19.242 00001344 HHC02272I From Sat Sep 03 12:06:19 2016 to Sun Sep 04
12:06:19 2016

12:06:19.242 00001344 HHC02272I MIPS: 812.147857

12:06:19.242 00001344 HHC02272I IO/s: 3236

12:06:19.242 00001344 HHC02272I Current interval is 1440 minutes

My gut feeling is that the high I/O capability can be attributed entirely to
the SSD HDDs.  Per Windows Task Manager, my memory usage never went over 22%
(of the 16 GB installed).

For the record, the processor is an Intel Xeon CPU Quad Core E3-1225 v3 @
3.20GHz, RAM is Hyundai PC3-12800 (800 MHz), and the HDDs are LITEONIT LCTs,
SATA-III 6.0Gb/s.  All components were acquired from Dell.

It looks like my tests from yesterday produced nearly identical results
today. But this time, I skipped running the Assembly and link steps and
simply ran the NBENCH steps in parallel. As before, with eight concurrent
NBENCH steps executing, all HercGui and Task Manager indicators stayed maxed
out at 100%. As you can see, without running the Assembly and link steps my
I/O numbers dropped like a stone.

15:57:33.967 00000450 HHC02272I From Thu Sep 01 15:57:33 2016 to Fri Sep 02
15:57:33 2016
15:57:33.967 00000450 HHC02272I MIPS: 899.872161
15:57:33.967 00000450 HHC02272I IO/s: 527
15:57:33.967 00000450 HHC02272I Current int! erval is 1440 minutes

My Windows Server is at the current Microsoft update level. Over this
weekend I plan to apply some Dell BIOS and chipset updates to the T20 server
and bring it up to current level also. I will then rerun my tests. Who
knows? Maybe the numbers will change. I'll be pushing for that magic 900
MIPS level.

Ivan,

Your TGV reservation with SNCF also wind up in TPF aka Airline Control
Program. TPF used to be maintained from VM, but now MVS is required and
those who relied on Pipelines under CMS had a problem.

When I did some performance measurements along the lines you suggest in
conjunction with what I thought should improve the code, my experience that
was that there was no correlation between what code I changed in Hercules
and where performance changed.

My theory is that Hercules performance is governed by cache misses because
the footprint of running even the simplest instruction is enormous. So
pushing a bit of code across a cache line might have a lot more effect than
saving a single x85 instruction.

I believe some recently posted that benchmarking was something of a 'black art'.  It may have been an off list email, anyway.

Be careful in stating 'nothing else has changed'.

NBENCH is self adjusting in that it can run more tests to get consistent results and if the CPU is fast enough then it requires more instances of a test to be performed.

In other words, on a 3 MIP system it may only run the series of tests by looping only 5 times on each.  Whereas on a 30 MIP system it may run the series of tests by looping 20 times on each.  So as you have loaded the system with multiple executions it may have slowed the capacity of the CPU(s) so that NBENCH is now executing a different number of testing cycles.

A fixed benchmark such as dhrystone or whetstone, doesn't self adjust like NBENCH.

That's an amazing mips rate. I looked up the E3-1225 v3, and Passmark rates it as 7080 vs the x5680 which is rated at 8767. Yet as an 8-way, the best I've seen is 350mips and 2400 io/s. I don't have SSDs, just iron drives but run as raid with a 512MB controller that delivers 280MB/sec avg at full blast.

I'm using 3.12, so if that's the sort of performance boost Hyperion gives, that's sure a good reason to upgrade.

I’m not looking at the performance numbers generated by NBENCH itself, just the numbers from HERCGUI as to work load.  I wanted to drive my machine to the max and see what HERCGUI says.  As with all my ten job stress tests, both the Windows Task Manager CPU monitor and HERCGUI CPU monitor show 100% on all four cores.  But, Windows still reports that I never go over 25% usage of installed memory (16Gb).  The performance increase using SSDs is simply amazing.  The Dell box runs cool and quiet.  The fans never turn on.  Plus, you never defrag the partitions.  How can you beat that?

 

I’m not trying to get actual benchmarks.  Rather, I’m trying to stress everything to see what she’ll do flat out.

 The 350 mips I mentioned, that's from the maxrates command, not any benchmark. This seems very odd. You have a 4 core box running eight jobs, and I have a  12 core box running 8 jobs. So in theory, each of my emulated cpu engines should get it's own core, while yours have to double up. Yet even so, you still get more than twice the speed, even though the 1225 is only about 40% faster on a per core basis than the x5680.

Maybe I should have bought a Dell. I can't run my machine at more than around 60% for any length of time or else the fans switch to high and it's just like being on the raised floor, heh. On the rare occasions when I reboot, the bios powers them to full for five minutes, and even though the rack is in the far basement, someone invariably starts shouting down the stairs that they can hear it and it better stop soon, lol.

Well, I ran the ten NBENCH stress JOBS again today. This time I changed all the ‘SYSPRINT DD DUMMY’ statements to ‘SYSPRINT DD SYSOUT=*’.  The result is that each job now generates 108,000+ lines of SYSPRINT, up from 72,000+ lines.  The average JOB wall clock time now went to 6.73 minutes.  That is down slightly from 6.93 minutes.  Again while eight NBENCH jobs are running, all my CPU cores were pegged at 100%, but my memory usage number went down to 19%.  Here are my new HERCGUI numbers which are impressive:

 

17:02:26.285 00000D8C HHC01603I maxrates

17:02:26.286 00000D8C HHC02272I Highest observed MIPS and IO/s rates:

17:02:26.286 00000D8C HHC02272I From Sun Jan 29 17:02:26 2017 to Mon Jan 30 17:02:26 2017

17:02:26.286 00000D8C HHC02272I MIPS: 910.316468

17:02:26.287 00000D8C HHC02272I IO/s: 2900

17:02:26.287 00000D8C HHC02272I From Mon Jan 30 17:02:26 2017 to Tue Jan 31 17:02:26 2017

17:02:26.287 00000D8C HHC02272I MIPS: 1026.198338

17:02:26.287 00000D8C HHC02272I IO/s: 1820

17:02:26.288 00000D8C HHC02272I Current interval is 1440 minutes

 

Why the IO/s rate went down so drastically surprised me.  I have no clue why that is.  I guess the creation of SYSPRINT DUMMY files somehow result in more IOs than SYSOUT= files.

Maybe because it had to do actual I/O it waited until the I/O buffer filled

RE: Stress Testing Hyperion under Windows Server, Updated

Hercules390 - General mailing list
Thinking my HERCGUI numbers from yesterday were an anomaly, I re-ran my ten job NBENCH stress test again last evening.  Here are the new numbers:

 

17:02:26.113 00000D8C HHC01603I maxrates

17:02:26.113 00000D8C HHC02272I Highest observed MIPS and IO/s rates:

17:02:26.114 00000D8C HHC02272I From Mon Jan 30 17:02:26 2017 to Tue Jan 31 17:02:26 2017

17:02:26.114 00000D8C HHC02272I MIPS: 1026.198338

17:02:26.114 00000D8C HHC02272I IO/s: 1820

17:02:26.114 00000D8C HHC02272I From Tue Jan 31 17:02:26 2017 to Wed Feb 01 17:02:26 2017

17:02:26.114 00000D8C HHC02272I MIPS: 1061.265864

17:02:26.114 00000D8C HHC02272I IO/s: 1612

17:02:26.114 00000D8C HHC02272I Current interval is 1440 minutes

 

I think I’ll bump up DEVTMAX value within the .CNF file from 16 to 32 and see what that does.  Who knows, maybe there’s more that can be squeezed from my machine.  It’s all virtual anyway.

Maybe because it had to do actual I/O it waited until the I/O buffer filled up?

Why the IO/s rate went down so drastically surprised me.  I have no clue why that is.  I guess the creation of SYSPRINT DUMMY files somehow result in more IOs than SYSOUT= files.

The 350 mips I mentioned, that's from the maxrates command, not any benchmark. This seems very odd. You have a 4 core box running eight jobs, and I have a  12 core box running 8 jobs. So in theory, each of my emulated cpu engines should get it's own core, while yours have to double up. Yet even so, you still get more than twice the speed, even though the 1225 is only about 40% faster on a per core basis than the x5680.

Maybe I should have bought a Dell. I can't run my machine at more than around 60% for any length of time or else the fans switch to high and it's just like being on the raised floor, heh. On the rare occasions when I reboot, the bios powers them to full for five minutes, and even though the rack is in the far basement, someone invariably starts shouting down the stairs that they can hear it and it better stop soon, lol.

That's an amazing mips rate. I looked up the E3-1225 v3, and Passmark rates it as 7080 vs the x5680 which is rated at 8767. Yet as an 8-way, the best I've seen is 350mips and 2400 io/s. I don't have SSDs, just iron drives but run as raid with a 512MB controller that delivers 280MB/sec avg at full blast.

I'm using 3.12, so if that's the sort of performance boost Hyperion gives, that's sure a good reason to upgrade.

The MIPS number went up by 98.168611, or 12.09%.  Again, that’s significant.  But IOs per second decreased by 336 or 10.38%.

RE: Stress Testing Hyperion under Windows Server, Updated

In reply to this post by Hercules390 - General mailing list

 I downloaded NBENCH from the files area to try it, since there must be something about the different programs that affect the different MIPS rates. I have 9 NBENCH jobs running and so far the maxrates command now says that MIPS = 959 and max io/s is 3650. Task manager says my 24 cores (HT is turned on) are at 34%. So that sounds better. Elapsed time comes in at 6.76 minutes for each job.

I did some testing and much to my surprise, Hercules performs better with Hyper-Threading than without. I had thought that having individual cores for each thread isolated from the others would yield better performance, since it would avoid the occasional stalls you get with the "other" HT core within the same core. That doesn't seem to be the case: with HT off, a single cpu gives 52 mips (with my homebrew test) and with HT on, it goes up to 60 mips. I guess Windows must do a decent job of dispatching to try and avoid using both sides of a single core. Interestingly, during IPL before the SIGP to start the other 7 cpu's, maxrates says the single engine has reached 207 mips. So from a theoretical 1642 to 959 mips, that's fairly hefty overhead for running as an 8-way.

Hey,
nbench is just a JCL right? Is this MVS version running in z/OS https://groups.yahoo.com/neo/groups/hercules-390/files/MIPs%20Testing/ https://groups.yahoo.com/neo/groups/hercules-390/files/MIPs%20Testing/?
All I wanted to know initially was how to benchmark my system :)

The NBENCH JOB I’ve been running contains all the Assembler source and JCL to Assemble and Link Edit to build NBENCH.  It looks like I loaded it on 08/18/2016.  It was loaded on my machine as nbench-b1.zip.

It looks like DEVTMAX does matter for NBENCH. I ran with it set to 18 and the results were not as good as with only eight. I just tried it with DEVT set to 10 and have seen the best result so far, MIPS=1053
and IO/s = 3789. Still only 207 mips for a single cpu during ipl, so I guess that's as good as it gets for this box.

With DEVTMAX set back to 16, the MIPS number jumped to 1028 .  After more  testing, I have found that my maximum MIPS number was accomplished by setting DEVTMAX to 14.  At that setting my MIPS number reached 1179.

 I just bought an i7-7700K which I think has just about the fastest single core speed there is. With DEVTMAX defaulting to 8, I get a maxrates of 1222MIPS, 6908 SIOS running with eight cpus. A single cpu yields a maxrates of around 242 MIPS, although my more generic benchmark says 119 MIPS.
