CMT processor load generator

Is there a tool that can load a CMT processor to the desired level?
For example, I have a 8-core CMT processor on which Solaris OS is running and I want to load 4 out of the 8 cores to 50%. (Using corestat utility, I should be able to see 4 out of the 8 cores are loaded to 50%)

I use The Grinder. grinder.sourceforge.net
You can develop your own test and control it the way you want.
Hope it helps!

Problem with public folder initialization on exchange load generator 2010

hi,
we need to make some stress charge for a migration between 2010 and 2013. Before that we need to populate our exchange 2010 lab with full mailbox and public folders. So we tried Exchange load generator 2010 for this task ( initialization only).
Loadgen did well for the mailbox but we have some problems with the public folders. we have an empty public folder database and the user we run loadgen with has organization admin and public folder management right. the problem is that when we run this command
(for initializing public folder only, mailbox's done) :
loadgencmd.exe /p /c config.xml /add trace.log
IT create only one public folder with the user we run loadgen with, and 5-8 objects inside. We need that It create a public folder for each users it created before. Maybe we do not understand loadgen
correctly...

I found my solution :
customize the <PublicStoreProfile> section in the configuration file as follows:
<PublicStoreProfile>
    <MessageFiles />
    <TopLevelFolderCount>1</TopLevelFolderCount>
    <NonTopLevelFolderCount>1</NonTopLevelFolderCount>
    <MinimumFolderDepth>1</MinimumFolderDepth>
    <AverageFolderDepth>2</AverageFolderDepth>
    <MaximumFolderDepth>3</MaximumFolderDepth>
    <MinimumMessageCount>5</MinimumMessageCount>
    <AverageMessageCount>10</AverageMessageCount>
    <MaximumMessageCount>15</MaximumMessageCount>
    <UseOrdinalFolderName>false</UseOrdinalFolderName>
</PublicStoreProfile>
Simply put differents values for each variables.

AJAX True Client issue with Load generator and BPM

Hi every one,
when i try to run Ajax True Client scrit from controller with Load Generator other than local machine,
it is failing with an error "cannot find usr file".
Root Cause:
this is because it is missing "webiendp.txt" file while copying the script to Load Generator machine. by placing this file manually in that location, its working fine.
But in case of BPM we cannot do like that. BPM always make a copy of the script and after execution it clean up the entire folder.
is there any settings to copy the entire folder to BPM/LG location, with out missing "webiendp.txt"?
thanks in advance.

Distribution model of cep load generator

Hi guys,
Do you happen to know the distribution model (eg. Poisson ,uniform...) of Oracle CEP load generator?
Cheers,
Alireza

Seems there is no documentation for this.
My curve fitting experiment shows it does not follow a particular distribution. For example for rate 100 tuple per second the distribution model is t location-scale for some queries, whereas for rate 50k and 100k the distribution is more fit to Weibull and generalized extreme value distribution.
I just wanted to insert some pics here but the system gives me error. Anyway, this is the answer.

MAXDB and benchmark factory(or any load generator)

hi
Has anyone tried running Benchmark Factory with MAXDB successfully ?
(This is the version i am running maxdb-all-linux-64bit-x86_64-7_6_06_10 to test our new platform)
If not, what load generator is recommended for use with MAXDB ?
thanks
A.

Hi,
I have not tested yet, but you can take a look at [url http://www.dominicgiles.com/swingbench.php]Swingbench that is a free load generator (and benchmarks) designed to stress test an Oracle database (9i,10g,11g). In addition, you can also take a look at [url http://www.oracle.com/technology/obe/obe9ir2/obe-mng/wkldgen/wkldgen.htm]Workload Generator but it seems it was designed to work on Oracle 9i.

8.01 processor load

The new 8.01 seems to be more stable however the CPU meter runs along great (low load) for about 10 minutes then all of a sudden I get heavy CPU load and the odd cut out. Last night mainstage crashed completely during a gig. I basically using 1 EVB3 patch
Has anyone experience heavy processor load after the software has been active for a 10 to 20 minutes
I'm trying to see if I have a hardware problem or not
JN

I just recognized that all of a sudden Spotlight started indexing iCal files (found out in Konsole:
22.12.07 00:26:58 mdworker[760] iCal.mdimporter: ignoring file </Users/Library/Application Support/iCal/Sources/1F2BE646-18F3-42B2-9D0C-66BA018AC293.calendar/corestorage. ics>)
- and the fans started blowing. Had a look in Activity monitor and the processor load jumped up to 50%.
That would be killing any hard activity with EVB3s.
Maybe there is a way to deactivate Spotlight before a gig.
00:26:58 is the right time to do maintenance for office workers but not for musicians.
That's the time when the crowd should get hot, not the processor.

MultiLink PPP Processor Load

Is there a large increase in Processor Load when using MultiLink PPP to bond T1s together while running MPLS? We have been requested to bond circuits for customers, but are reluctant because of the danger of over utilizing the processor on our 7206s which are mostly NPE-400s and some NPE-G1s. Is there a reference somewhere to the increase in Processor Load caused by MPPP?

Hi,
Cisco does not publish quantitative details on the impact of MLPPP on CPU utilisation. So the best option for you is to do some baselining within the lab: start with an unloaded box with two separate T1s, pass traffic over them so that they are both fully utilised and then note CPU utilisation. Then, enable MPPP over these, pass traffic over the multilink interface so that it's fully utilised and then note CPU utilisation. That should give you some idea of the incremental impact of such interfaces. You can always do things such as disable fragmentation when using MLPPP which does reduce CPU utilisation.
Having said that, the NPE-400/NPE-g1s are pretty grunty and should be able to handle a few multilink interfaces. It comes down to how many of these interfaces you are expecting to use...
Hope that helps - pls do rate the post if it does.

100% processor load

Hello there,
I checked out a new strange behavior with TestStand 3.1 and LabVIEW 7.1. I use a SubVi in a Step to get the SubPropertiesNames. (See "GetSubProps2.JPG") I want to code it right and used the "Merge Errors.vi", because if the "Close Reference.vi" gets an error the reference will not be closed. But after closing the Step after calling via EditStep-method, the processor load goes up to 100%.
I had hard to search for the cause. I had to remove the "Merge Errors.vi" that it will be work. (see "GetSubProps1.JPG") But why?
I can't understand this strange behavior. So if somebody has a made a similar experience - please answer..
Ciao TPoint

Hi TPoint,
It probably is working but it depends how big that error cluster is, it could be quite large, an you know what happens to labview an larger array of clusters can do, especially if they is no delay in a loop. Basically it grabs all the processor.
There was a problem, I think the change from labVIEW 5.x to labVIEW 6.0, (I think) which caused a problem in the LabVIEW Operator Interface. This was resolved by passing the reference through a shift register, as you have done with the error.
Now, I also do this with references.

Parallels vs Fusion and processor load

Parallels causes my MBA to run very hot and causes the fans to run at full speed.
Does anybody know if Fusion has the same effect or does it cause less processor load?

Pagemakers2 wrote:
Can anyone confirm if Fusion applied the same load as Parallels? If it's a Windows thing then I guess it does.
Yes, I can confirm it. In this aspect, there is no difference between Fusion and Parallels. Once Windows settles down and gets updated, it will run much more quietly. Windows will always have a tendency to cause more CPU and fan usage. It's normal.
Also, there was a bug in Fusion (maybe fixed now?) that caused the airport process on the Mac to spike to 100%, whether Windows was running or not. That is a different issue. Parallels vs. Fusion is somewhat of a religious war. People like one or the other. When it comes to Windows CPU and fan usage, they will be the same.
I know it makes my MBA warm and causes the fans to run at full tilt. Will it also do the same thing on an iMac?
Yes. You don't really have to worry about it though. Any process that causes high CPU usage will do that. The fact that the fans come on is a good thing and means that the Mac has control of things and won't let it go too far.

HP Load Runner: CPU usage for this load generator has exceeded 80%

Recently I have downloaded LR 12.1 and installed. Observed error CPU usage for this load generator has exceeded 80% when executing the test with 5 user load using AJAX Trulcient IE script. For each virtual user in the script one TcWebIELauncher.exe hads been initiated and running during the test execution. Each TcWebIELauncher.exe instance is taking min 14% CPU utilization and CPU utilization for 5 users is around 75% at the time of test execution. What is the reason behind this high CPU utilization for this less user load?. Please suggest how to handle and fix the issue.
regards,
Sreekanth

You can download Trail version of Loadrunner from HP site. That's true. all HP testing tools products are license based.
i) If you want to use for SAP applications, you need to have SAP protocals (SAP GUI and SAP WEB). So how this licenses works is, if you want to buy 50 Vusers for SAP it cost you around $ 32k and it depends on company discount. so you need to work with HP Sales team to get the quotation then based on no of Vusers and you can procure it.
ii) As for as i know, there is no HP LR integration with Solution Manager.
let me know if you have any questions.

Sync-server process running with about 30% processor load

Hi there !
After installing 10.8.2 I have this issue.
Can anybody explain to me, what is going on with this process.
Does it stop or is there anything I must do ?
Thanks in advance !

I had the same symptoms and found a solution. I went to System Preferences>iCloud. I clicked "sign out". I agreed to all of the windows that poped up. Then I restarted my laptop. Then I went back to System Preferences to sign back into all of my iCloud services. After this the issue went away. It seems like Contacts was constantly trying to sync something, but reseting my iCloud acccount on my laptop seemed to stop SyncServer from running at 20% of my processor load 24/7.

Download load generator

Exchange Load Generator 2013 "well known" profiles

We are about to start testing Exchange 2013 implementation in new centralised configuration. We have figures for current user behaviour and need to ensure system can support expected workload.
Cannot find accurate documentation that describes what's in the 'well-known' profiles for Exchange load generator 2013. In previous versions, there were 'light', 'medium', 'heavy' and 'extraheavy' profiles that were totally defined within Loadgen.
The only references I can find are in the Exchange Load Generator word document that encourages the use of these without defining any of them.
The only sample I can find is in the profiles directory where there is how-to.txt that has an example of a customized MailboxStoreProfile with WellKnownProfileType "150M".

Like I said in my response to your other post in this thread, I wouldn't try to be too clever with this tool. Tune the parameters to get the number of IOPS you want in your disk subsystem, and then measure the performance. If you can get the
required I/O performance, i.e., 10ms maximum average log write latency and 20ms maximum average database read latency with peaks not exceeding 100ms, while sustaining the required number of IOPS, your storage subsystem is good.

Exchange Load Generator 2013 ActiveSync usage

Exchange Load generator 2013 is announced as supporting ActiveSync. In the modules directory there is a Microsoft.Exchange.Swordfish.Extensions.ActiveSync dll.
I'm looking to find any documentation about how to set this. I am about to conduct a test with a large rate of ActiveSync and need to know how I can specify this. There's nothing I can find in the supplied word document.

Just between you and me, I wouldn't get that clever with LoadGen. It's a great tool for generating transactions primarily for testing disk subsystems, but it's really time consuming to get it configured for testing the various protocols.

Is it possible my FieldPoint's clock is getting extended due to processor load?

I am trying to measure a signal that is around 10 Hz using the cFP-AIO-600. It is a basic pulse counter .vi that I am uploading into the cFP-2020 that counts all pulses that occur in one second . The odd thing that I am seeing, is that it is counting more pulses than I expect. Instead of 10 pulses per second, it is counting 32. The timestamps of each datapoint "verify" that this occurs in one second.
When I add more functionality (by adding a Collector module and a waveform graph), it somehow counts even more pulses for the same frequency signal. Up to 347 pulses!
How is that possible? It can only be one of two things:
1) The signal actually got faster in between the two measurements (unlikely).
2) Additional .vi code on the cFP causes the clock to get confused, and the 'second' that I am measuring is actually longer than a second by a significant margin.
I have verified this several times, running the second scenario right after the first scenario. The run time of these .vi's take longer than a second (and the .vi with the Collector does seem to take about 10x as long) but this evidence is not as supportive to my theory due to the time introduced by my computer and the cFP communicating with each other and updating graphics.
I have attached these two examples. You will not be able to run them yourself (because of the data access form the cFP-AIO unit) but I have made the results that I got the default values. You should be able to see both my code and the results I got illustrated above when you open the .vi's. pulse_problem_1 shows the first scenario, and pulse_problem_2 shows the second, which is the same thing as pulse_problem_1 with only the Collector and waveform display added.
What can I do to resolve this? It's only a 10 Hz wave, and I know cFP can count even faster signals, so something in my .vi must be wrong. Any help or advice you can give me would be appreciated.
Thanks.

Okay, I have proof that my FieldPoint is lying to me when I ask it to do 1000 iterations of 1 wait-until-next-ms loops.
I started with the very useful example in the RT package called "NI Timestamp Code Timer" which, I can only assume, calculates the known timestamp discrepancy caused by processor load. My attached picture (talyor_loop_vs_time_discrepancy2.JPG) shows that right before the cFP-AIO-600 module records a positive voltage, the normally 1 ms loop can take as long as 60 ms. That's fine, but the FieldPoint then reports that only 1 ms has occurred! As you can imagine, this has made pulse counting very difficult, for instead of measuring 10 pulses per second, it 'thinks' it is counting ~28-30 per second as each pulse causes a measurement delay that the FieldPoint treats as a regular 1 ms time interval.
I have also attached the Loop Test code, and a picture of the signal through an ocilliscope, proving it is a regular square wave.
Why does this occur with positive voltages only? Why doesn't it take the same amount of time to read voltages equal to zero? If the delay was constant on every read, I could compensate for it, but I can't compensate for this delay that only occurs on positive pulses!
Please help!
