No CPU core reserved for ESXi Scheduler

Hi,
I have a customer who uses UCS C210 M2 servers with ESXi 4.1 to host UC 8.6 applications including Unity Connection.
The SRND and Docwiki both state that, as the UCS is hosting a Unity Connection system, a core should be reserved for the ESXi Scheduler.
Unfortuantely this requirement seems to have been missed by the install team and the vCPU requirements for the installed machines add up to 8 leaving none available for the ESXi scheduler.
Can anyone tell me the implications of this other than it breaking the Cisco rules for deployment and thus being an unsupported environment.
The kind of things I need to know are will this just effect Unity Connection or all the hosted VMs including CUCM, CUPS etc.

Hi Richard,
Thanks for opening a PDI ticket for this. I just want to include the information I gave you on the post so it is available for future reference. According to the link below:
http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/connection/10x/requirements/10xcucsysreqs.html#pgfId-360874
"For VMware vSphere ESXi 5.5 and later, you do not need to leave any unused processor core for the ESXi hypervisor / scheduler. The Latency Sensitivity functionality has been introduced to reduce virtual machine latency. "
You need to set Latency Sensitivity to HIGH to be able to leverage the above support. Please refer to the attachment to see where to change this parameter.
Hope this helps!
Regards,
Tere.

How to calcuate how much cpu/cores needed for an amalgamation of databases on a single instance

Hi all, We have been given a project of producing a high level hardware spec for a new oracle linux server that would be an amalgamation of our current 5 windows servers all running Oracle 11203 Windows 2008 r2. All our windows boxes are Intel dual core with 12 cores each. My question is how to measure how much cpu is our current each oracle database is using to determine the min cpu/cores required for the new linux box? Hope i make sense. Thanks!

Hope that above excerpts from AWR reports can tell how much cpu is consuming each database , because for each database you will run awr report and then compare them .

CPU clocking 100% for Master Scheduler

Hi
Most of the time my Master scheduler is clocking 100% CPU. There are 6 process schedulers. 2 are dedicated process scheduler(not defined as online app servres in Configuration.properties file on Webserver) where as 4 are process scheduler as well as online app servers. Problem is that all those users who are connected to Master scheduler server are experiencing Performance issue. Other 3 online servers are not so engaged as CPU utilisation for them is between 6% - 20% only.
My question is is this set is adviceable ? or making one of the dedicated process scheduler as Master scheduler will help?
My hardware configuration of all appservers is 2 x 2.4 Intel Xenon HT and 3GB Ram.
Regards
Vishal Mahajan

Hi Marchiom
Thanks for your reply. Following were the processes that are running on Master Scheduler at time when it clocked 100%.
pspubdsp.exe
psqrysrv.exe
jsh.exe (20 different instances)
pssamsrv.exe
psappsrv.exe (350K x 2 instances)
Not sure which one was keeping CPU occupied? I'll keep an eye again and see which one is picking most CPU%.

Skype maxes a cpu core periodically for several seconds and does not respond

Skype 7.7.85.103 uses a lot of cpu periodically, and is not reacting for several seconds.
I am not sure, if this is related to advertisements changing in these intervals, but if it is, then this should not be happening.
I already did a clean install (inclusive removing EVERYTHING from the registry), and it did not help.
I tried as administrator - once again, it did not help.
It is less visible when I am connected to a powersource, as the cpu is then going faster, but it still happens.
And it is not the first version that has had this problem.
In case it may help, there is the dxdiag.txt attatched.

hello, in order to further diagnose the issue, could you run firefox in safe mode once & see if the problem is occuring there too. please report back afterwards, thank you...

Decreasing voltage for CPU core

I have decreased CPU core voltage for my P4 2,8GHz from default 1,525V to 1,5V which helps me to decrease CPU full-load temp. from 61-62°C to 58-59°C. System is styl rocky stable. Is there something negative/dangerous on decreasing CPU core voltage?
Thanx

Pinning physical CPU cores for VMs

Hi all,
Let's assume we have OVM Server pool on two-node Dell R900 Hosts, FC switches and SAN. One server is acting as the Server Pool Master and Utilty Server, as well as the OVM Server. The other Dell R900 server acts as the OVM Server. Both Dell servers have two quad-core processors and are configured as active/passive. VMs are meant to be on SAN but will need memory and CPU from the phyisical servers in two-node Dell r900 hosts.
Is it possible to specify cores for the first VM as cpus='0,1,2,3' and the second VM as cpus='4,5,6,7' in both vm.cfg to avoid the situation when they will both use the same first four cores on the same phyisical server? I know it is more expensive lto use all 8 cores but is inevitable since the two applications in two VMs will need a lot of processing power.
What would be your recommendation how to configure vm.cfg and cpus parameter for two different VMs?
Cheers,
Andrei

I am in a very similar position where we have 2 CPU license for Oracle DB. I would like to use this to run two separate databases on separate OS instances. One will be an OBIEE database and the other will be an Oracle Retail database. I'd like to assign both guests CPU 0,1,2,3 and let them share the CPU resources but I don't know if you can do that with "Hard Partitioning".
Interesting side note - since the servers I bought are running the Intel X5680 CPU's they have the new style Nehalem hyperthreading. This means that on my 2 socket server I have a total of 12 CPU cores (six core CPU's) and each core has two threads. This shows up as 24 CPU's on the Oracle VM server. If I read the licensing correctly I can run my 2 CPU's on 4 cores which means I should be able to assign 8 CPU instances and meet the database CPU licencing requirements - RIGHT?! - thoughts?

What is the optimum number of CPU cores for Photoshop CC?

The title is the question.

To reinforce what Chris has said, keep in mind there's only one processor package in the new Mac Pro. There are cases where having two packages - such as in the previous design Mac Pro with dual Xeon x5600 series processors - can actually be a pretty big advantage.
That being said, I've put a lot of thought into how many cores a new Mac Pro ought to be configured with to run graphics software well, and I've come to the thought that 4 is too few and 12 is way too many. I believe the 3.5 GHz 6 core E5-1650v2 may actually have a slight edge over the 8 core E5-2667v2, because with 12 logical Ivy Bridge processors cranking full-on (with Hyperthreading) the memory bandwidth is actually already going to be taxed. And of course the 6 core is much cheaper.
There's a nice little Photoshop benchmark that's reasonably indicative of how well a system actually multithreads with Photoshop. It can be found here:
http://ksimonian.com/Blog/2010/02/24/improved-photoshop-benchmark-cpu-speed-test-for-both- mac-pc-free-radial-blur-filter-test/
I have a PC workstation with the same chipset as the pre-cylinder Mac Pro (dual Xeon x5690s in my case), and my best speed for that benchmark with Photoshop CC equals the best posted on that site: 8.3 seconds. People are reporting the new Mac Pro is scoring with that benchmark in the same vicinity - but not really faster.
Do some research yourself and see what various folks with the new cylindrical Mac Pro are scoring on that benchmark. I'd be interested to hear if your findings are like mine.
What's your system score, Chris?

CPU and RAM for TimesTen

I have test performance statistics for our java application (using oracle db) on a 4 X Quad-Core AMD Opteron™ 8360 SE cpu node with 64 GB RAM.
I am trying to collect performance statistics for TimesTen on a 2 X Dual Core Intel Xeon 5160 cpu node with 8 GB RAM.
My question is how does TimesTen treat processors. Is dual core considered as 2 cpu or single cpu?
So am I comparing performance - (2 X 2 = 4) TT vs (4 X 4 = 16) Oracle DB ?
Any suggestions on how should we compare the performance statistics obtained on the two machines ?

Please see my answers embedded below:
1. Under what conditions does TimesTen use multiple processors ?
CJ>> There are many background daemon components to TimesTen that are multi-threaded and may use multiple processors to some extent as required (main daemon, sub-daemons, replication agent, cache agent).
The main daemon is a very lightweight process that is purely supervisory in nature. It is not involved in database transatcion processing etc. and so its CPU usage is very low.
Each active datastore (database) has a dedicated managing sub-daemon. Again, this is not directly involved in transaction processing but it too has several threads. The checkpointer thread may use a lot of CPU while a checkpoint is occurring. The log flusher thread will use CPU in proportion to the intensity of write operations (primarily INSERT/UPDATE/DELETE) in the application workload (this thread is responsible or flushing the transaction log buffer to the log files on disk).
If replication, or AWT caching, is used the replication agent transmitter and/or receiver threads may use significant CPU depending on the replicated workload.
If Cache Connect is being used then the cache agent threads may use significant CPU when e.g. an AUTOREFRESH is in progress.
These ar all background activities and you do not have direct control over how many CPUs or how much CPU time is used by them. They will try and use what they need and the O/S will allocate them time based on available system resources.
Equally significant is the CPU power used to process application transactions. Each application process/thread that is executing via a separate connection will potentially be executing concurrently within TimesTen hence if you have 20 application threads (or processes) each with its own connection to a TimesTen datastore then TimesTen could potentially use up to 20 CPUs/cores concurrently. This is the key factor in your ability to control how many CPUs/cores TimesTen. The crucial things to understand here are:
1. In direct connection mode there is no dedicated TimesTen server process. All DBMS logic is encapsulated in the TimesTen library (libtten.so). All database query and transaction processing is actually executed in the context of the application thrad that makes the database call. Hence, as I mentioned, if there are 'n' concurrent application processes/threads each with a separate database connection then TimesTen can potentially use 'n' CPUs/cores concurrently. Essentially, # concurrent connections = max concurrent CPUs/coires.
2. In client server there is a dedicated server process or thread (depending on configuration) for each application connection and so again # concurrent connections = maximum number of concurrent CPUs / cores that will be used.
2. What techniques do I use to ensure maximum performance on this -
a. Machine with 2 cpu (each is a dual core processor) and 8 GB RAM.
CJ>> The number of physical CPUs (chips) is irrelevant. What matters is the number of cores. In this case 4. So, the system can concurrently execute up to 4 tasks. Anything more than 4 and tasks may have to wait for available CPU in order to execute. Since there are no blocking operations within TimesTen database processing then from a TimesTen perspective this machine can execute 4 application threads performing database access at maximum speed. Of course in reality CPU time is needed for the application, O/S, TT background processes etc. etc. so one would aim for fewer than 4 concurrent database processes. This assumes of cousre that there is no blocking at the application level either and that these processes or threads can therefore spend 100% of the available time executing. If the application blocks for any reason (e.g. waiting for the next 'request' from somewhere) then this introduces idle toime and so one can increase the number of concurrent application processes/threads to use up this idle time thereby increasing overall throughput.
b. Application using direct connection mode with weblogic Application server
CJ>> See my comments above. Generally one would use a connection pool and configure the number of connections to optimise performance (some experiments will be needed to arrive at the optimal value since it is very much dependant on the application workload and processing model).
c. All data is cached in TimesTen (using Cache Groups) for read intensive operations (There are few write operations as well but TT is mainly for the reads). Should the connections be 4 or 3 in this case ?
CJ>> If the volume of cache refrshes is low then you don't ned to 'reserve' much CPU for checkpointing logging and so you have all 4 cores available for application+database processing (plus O/S etc.). If the application is mostly using the database and not waiting for stuff outside the database then the optimal number of connections is probably in the range of 3-6. If the application does a lot of non-database work which may include waiting for things then the optimal number of connections will be much higher. Again, you need to experiment to find out what is optimal.

ASA 5515-X not addressing all CPU cores/memory?

Hello all,
I appologize if this has been answered somewhere, but I've been googling the heck out of this and haven't seen this addressed anywhere.
I have a new ASA5515-K9 running code version 8.6(1)2 for personal lab use, and the output of the "show cpu core all" and "show memory" commands don't appear to match what is physically in the box.
For example, the processor is the intel i3-540 with 2 cores/4 threads, yet it appears the OS is only using 1 core, as shown below:
ASA5515X# sh cpu core
Core      5 sec 1 min 5 min
Core 0     0.0%   0.6%   0.3%
Furthermore, Cisco states the 5500-X series run a 64-bit OS, 8.6.1, yet it seems to only be addressing 4GB of memory:
ASA5515X# sh mem
Free memory:        3477981888 bytes (81%)
Used memory:         816985408 bytes (19%)
Total memory:       4294967296 bytes (100%)
The hardware is correctly identified in the output of "show version" and during bootup, as follows:
Sh Ver:
Hardware:   ASA5515, 8192 MB RAM, CPU Clarkdale 3059 MHz, 1 CPU (4 cores)
                 ASA: 4096 MB RAM, 1 CPU (1 core)
Bootup:
CPU Type: Intel(R) Core(TM) i3 CPU         540 @ 3.07GHz, 3059 MHz
Total Memory:8192 MB(DDR3 1333)
System memory:624 KB, Extended Memory:3573 MB
So in summary:
1. Why does "show cpu core" and "show cpu core all" only show 1 core? I was expecting output similar to https://supportforums.cisco.com/thread/2158189
ASA23-19(config)# show cpu core
Core      5 sec 1 min 5 min
Core 0     0.4%   0.2%   0.2%
Core 1     0.4%   0.3%   0.2%
Core 2     0.2%   0.1%   0.0%
Core 3     0.2%   0.0%   0.0%
2. Why does only 4GB of 8GB appear to be available in "show memory"?
3. Why does "show version" display two seemingly separate hardware specs?
ASA5515, 8192 MB RAM, CPU Clarkdale 3059 MHz, 1 CPU (4 cores)
vs
ASA: 4096 MB RAM, 1 CPU (1 core)
Thanks in advance for any input.

Thank you for your responses. I didn't anticipate 3 out of 4 threads and half the memory being reserved for IPS features that aren't in use/configured. Given that firewall + IPS throughput on the 5515 is rated by Cisco for at least 200Mbps less traffic than firewall-only throughput, I had assumed there was no hardware explicitly reserved/dedicated to IPS.
I'm glad to atleast know everything's working as intended.
Thanks again!

Macbook Pro CPU Core's temperature measurments

I have a late 2011 15-inch Macbook Pro OS X 10.8.4 with BootCamp installed.
In OS X environment, the CPU core temperatures are around 40 - 44C, while in idle or with a minimum Safari browsing the net.
When in Bootcamp with Windows 7 Professional, in the similar operating/application condition, but the my Macbook's CPU Core Temperatures are always about 52 - 55C (10 degrees higher than in OS X).
While doing heavy stuffs such as Virus Scan, Time Machine, Data Backup, Video Editing etc ... on both environments the CPU core temperatures could go up to upper 80's degree C.
Is it normal ? if so, is there any explanation for 10 degrees warmer while in BootCamp/Windows ?
Thanks

The earlier version of FF brought all my previously open sites back after a system shut down (like for a scheduled windows update or similar). Now this is not happening any longer. What can I do? I liked this feature a lot and really miss it!!

I could choose to have all my previously open tabs brought back when the computer - accidentally or on a scheduled update - suddenly closed down. Sometimes I have windows open for several days with articles and sites that I spent time with finding. Now they are all gone and I have to painstakingly try to get them back.
Is it my mistake? I can't find any selection or choice in the tools menu that I could reinstate this useful function with. What happened?

hello; i just erased the post i started with, because my status has changed. i searched in the firefox folder and found the uninstall folder, and this time, uninstall worked perfectly, and it gave me an option to save my personal info! YAY! i installed ff 3.6.24 without a hitch; FF is Baaaaaack!
However, I did get a window saying my computer doesn't have enough resources for the latest version of 8, but that I should install the latest compatible version of firefox; which version would that be, I wonder? It takes me to the same page with the ff 3.6.24 downloads. I already have that now.
I am going to mark this as solved; thank you cor-el for helping me with this problem and sticking with me as i whined and moaned, and tried to get the courage to "just do it!"

I don't think so.
I have enough experience with LR to know what to expect for various activities.
Previews for all photos had been rendered long before I initiated the Save Metadata.
Metadata for 50 of the 52 files had already been written.
The high cpu had gone on for at least 5 minutes.   I switched to another app imediately after initiating the Save Metadata for the 52 files and only went back to LR when I heard my CPU fan running for a long time.
When I got back to LR, I saw the "Could not save metadata" window. I clicked "Show in Library" and OK. As soon as I did that, CPU usage went back to normal.
I've experienced the exact same scenario, where LR can't save metadata for all photos and I've never had LR get stuck consuming a very large amount of CPU.
As a test, I selected 118 other photos, changed metadata for all of them and then selected all and saved metadata. LR took about 20 seconds to save metadata for all 118 and LR CPU usage never went above 17%. The difference is that LR did not show the "Could not save metadata" window.

Load balancing on CPU cores

Hi,
We have a supermicro server with 2 x E5-2660 processors and 160GB of memory.
The only role assigned to this server is Hyper-V and we have about 100 VMs each with two vCores provisioned on this server.
I checked the cpu load by monioring the %Processor Time counter and noticed that while 10 out of 32 cores are at 100%, 15 of them are below 10%.
I am wondering if it possible to balance the load on the CPU cores to improve the performance and utilize the full processing power of each CPU.

Hyper-V will schedule things appropriately - most likely better than any manual intervention could provide. It could be the nature of your applications.
Hyper-V does provide the ability to assign memory weightings to different VMs if you really want to get into that.

Can Essbase uses SGI 80 CPU core, 960GB super computer Octane III?

Recently SGI annouced a super computer that can support max 20 Intel Xeon X550 series CPU (total 20 * 4 = 80 CPU cores) and 960 GB memory (96GB * 10). Can Essbase support this kind of hardware deployment to gain maximum system performance?
The server can be used for Linux or Windows Server 2008 platform.

Is Essbase supported on Windows Server 2008? If so, why not. Wintel is wintel is wintel.
And I know you would be just the guy for this box. :)
Are you seriously considering this for Essbase? It would be fun to throw some benchmarking tests at a box like that. If your company buys this beast and applies it to Essbase, please tell us all about it, really.
Once upon a time, Hyperion used to taunt Oracle with benchmarking tests against Express or whatever Oracle called Express/OFA back then.
So, how fast do you think Sample.Basic would run on this machine? :)

Only one CPU core recognized [solved]

For some reason the kernel only recognizes one CPU core out of two. I'm not completely sure at which kernel upgrade it disappeared but it is gone in 2.6.36 and 2.6.37. I know it was still there in september 2010 and earlier. I'm using a x86-64 kernel.

Motherboard is: Gigabyte MA770T-UD3P. I use the latest bios.
I have tried adding the kernel options "acpi=off noacpi apic=off noapic" as to the suggestion of a ubuntu bug report in launchpad but it didn't help. I also disabled ACPI in the bios but I'm still limited to one cpu core.
Any ideas?
[SOLVED]
I just doublechecked the BIOS settings and it had the CPU Core Control set to manual and one core was disabled. I set it to auto again and now both cores are recognized correctly. I don't recall ever touching this setting but at least it works now. Maybe a bios update actually changed the setting or (more probable) a friend of mine.

there just have ONLY ONE CORE %sys 100
the top command show average of all cpu core sys% usage
when the one core sys% is 100%
the system are very slow .
e.g: when I create a database instance used for a long time . over 2 hours
but generally it will be done at most 1 hours or shorteris any type of OS virtualization involved in this environment?
