• How can I access cpu temperature readings using c#?

  - by Paul

  For a programming project I would like to access the temperature readings from my CPU and GPUs. I will be using C#. From various forums I get the impression that there is specific information and developer resources you need in order to access that information for various boards. I have a MSI NF750-G55 board. MSI's website does not have any of the information I am looking for. I tried their tech support and the rep I spoke with stated they do not have any such information. There must be a way to obtain that info. Any thoughts?

• My CPU hits 100°C... Help me!

  - by JamesT

  The safe limit for processors is typically 50°C or so, but I have found that my CPU likes to do up to 100°C. I have got these readings from SpeedFan 4.42. I have a Intel Quad Core unclocked. I am using the standard intel fan with heatsink that came with the prossesor My case is a Cooler Master and I have two fans installed on the case. I took the side off to see if that helped. It lowered the temp be 3C. I don't really want to blow the processor and I don't know how to cool it down.

• IP Helper service uses 50-60% CPU every 1 minute for 3-4 seconds on Windows 7

  - by Sarveshwar

  I have checked everything - all the processes in the process explorer. IP Helper service is causing CPU usage of over 50 % every 1 minute for 3-4 seconds then comes back to normal. In the task manager, the process is svchost.exe and the service is iphlpsvc. Here's the result of "ipconfig /all" command: ![alt text][1] [1]: From Snapshots Here's a screenshot of "netsh interface teredo show state" command: ![alt text][1] [1]: From Snapshots Please help me resolve this.

• How to maximize Java resources for gaming?

  - by Keidax

  I notice that when I play Minecraft, my CPU usage is only around 15 to 20 percent, at most. Is it possible to force my computer to allocate as much RAM, CPU time, etc. to the game, in order to get the best experience possible? Or, is the low CPU usage due to limitations in the JVM or the game code itself? I have OptiFine installed, and I've already tried using renice to change the process priority and -Xmx to allocate more memory to Java. What else can I do?

• Why is Thunderbird pegging a core at 100%?

  - by david6

  I have experienced 2-3 unexplained lockup over last 10 days. Today, I had a random lockup (no mouse, keyboard response, 100% CPU). But, when I finally switched (Ctrl-Alt-F1) to command line (it took several minutes) it told me that thunderbird-bin had locked a CPU. I ran this to resolve: pidof thunderbird-bin sudo kill #### However, after saving other work, I tried restarting Thunderbird. It went to 90%+ CPU, and within 20 seconds it locked again. Once I have more detail I will raise a bug (on Ubuntu Forums). Does anyone have any other suggestions, advice? UPDATE Thunderbird 13.0.1 is quite stable in safe mode. Still working to resolve ..

• CPU Usage relative to number of users? - ASP.Net Application

  - by soldieraman

  My Asp.net application uses 25-30% of the CPU on a test server which has 600 MB Ram on it. I can see the asp_wb process taking that much percentage of CPU. This is when I am testing using one user. How many users can the server afford then without falling over? Is there a relationship between the CPU Usage and number of user aka if there are 2 users my application will sky rocket to 60% of memory usage? Or does/Should/How does the server handle this?

• Why does the CPU window always appear when trying to debug my project after a rebuild in Delphi 2010

  - by James

  Hi, Whenever I rebuild my application and try to step into a break-point the CPU window always appears. From what I understand the CPU window appears when DCU does not match up with the source file, however, in my case the DCU's are defintely being re-compiled and there are no old ones lying around or anything like that. The strange thing here is if I close down the application and re-open the project, place the breakpoint and run it works fine. I can even modify files and just press F9 to run the project and it works fine....it only seems to be when I rebuild the project (via IDE Project menu or the project context menu) that this CPU window never breaks into the source (even though it can find it!). I also noticed in the callstack a unit called Generics is always the top of the stack, never the unit my break point is in, this is no way related to where my break point is. Any ideas?

• Will an IO blocked process show 100% CPU utilization in 'top' output?

  - by Alex Stoddard

  I have an analysis that can be parallelized over a different number of processes. It is expected that things will be both IO and CPU intensive (very high throughput short-read DNA alignment if anyone is curious.) The system running this is a 48 core linux server. The question is how to determine the optimum number of processes such that total throughput is maximized. At some point the processes will presumably become IO bound such that adding more processes will be of no benefit and possibly detrimental. Can I tell from standard system monitoring tools when that point has been reached? Would the output of top (or maybe a different tool) enable me to distinguish between a IO bound and CPU bound process? I am suspicious that a process blocked on IO might still show 100% CPU utilization.

• Ubuntu 11.10 doesn't detect Intel integrated graphics (i7-2670QM CPU)

  - by Telmo Marques

  The laptop I'm using is an MSI GT683DX-847PT that comes with an NVIDIA GeForce GTX570M discrete GPU, and an Intel Core i7-2670QM CPU. According to Intel's description of the Core i7-2670QM CPU, it has an HD Graphics 3000 integrated GPU. The problem is that the Intel integrated graphics GPU doesn't come up in lspci nor in lshw, only the NVIDIA GPU shows up. Here is the output of both commands: sudo lspci: http://pastebin.com/raw.php?i=9AZg8bJy sudo lshw: http://pastebin.com/raw.php?i=6cAMFQsY I was counting on having two GPU's to run CUDA programs on the discrete NVIDIA GPU, while X was handled by the integrated Intel GPU, to prevent kernel execution timeout. Why doesn't the Intel HD Graphics 3000 GPU show up? Any tests I could make to verify the presence of an integrated GPU?

• What are these CPU cache settings? Snoop Filter, ACL prefetch, HW prefetch

  - by eater

  I was in my BIOS setup turning on VT-x support today and saw these other settings. A little googling indicates that they each seem to turn on some sort of optimization to do with the CPU's L2 cache. They were all turned off by default. The processor in question is an Intel Xeon quad-core 3.4GHz (X5492). My OS is Linux 2.6.35.10-74.fc14.x86_64 #1 SMP Thu Dec 23 16:04:50 UTC 2010 x86_64 x86_64 x86_64 GNU/Linux. I have 4GB of RAM if that matters. Here's what the BIOS manufacturer has to say: Snoop Filter Enabling the snoop filter typically improves performance by reducing snoop traffic on the frontside bus in dual processor configurations. Well I like the sound of improved performance. Why would the BIOS have this off by default? Or by dual processor do they not mean multi-core? Regardless, is there a downside if this is on? ACL Prefetch When enabled, the Adjacent Cache Line Prefetcher fetches both cache lines that comprise a cache line pair when it determines required data is not currently in its cache. When disabled, the processor will only fetch the cache line required by the processor. HW Prefetch Fetches an extra line of data into L2 from external memory. Both of these sound like optimizations that have some drawbacks. What are the reasons to turn them on? What are the reasons to leave them off. Why is the default off?

• Should I buy more RAM for my computer or a better CPU?

  - by Reijer The Coder

  I have recently bought a new laptop, an ASUS N56VJ-S4149H. I bought it to use it in all possible ways I could want, so that would be gaming downloading and streaming movies browsing the web and programming software. So far it has been running great but one thing annoys me a little bit. I frequently play Mount&Blade: Warband, it's a great game and you should check it out. Everything runs smoothly but only when I turn down the 'Texture Detail'. Otherwise it will lag a lot and I can't really play. Now my question is: Is this a problem of not enough RAM? At first I was really sure it was but after thinking about for a while I'm not anymore. My computer only has 4 Gigabytes of RAM and there is still a slot open. So will it improve when I buy another 8 Gigabytes? EDIT: It has an Nvidia GeForce GT 635M inside. and an Intel Core i5 3230M CPU with 2,6 GHz. Help and answers are really appreciated. Thanks to all.

• Static Memory allocation & Portability

  - by user332354

  I have read Static Memory Allocation are done during Compile time. Is the 'address allocated' used while generating executables ? Now,I am in doubt that how the memory allocation is handled when the code executable is transferred completely to a new system. I searched for it but I didn't get any answer on Internet.

• cpu usage nearly 100 constantly windows xp sp3

  - by user33882

  When running some heavy applications like games or virtual box for some time.. the cpu usage is normal for some 15 mins and then suddently cpu usage increases. even after i quit the heavy apps and when i start some other apps, the cpu usage of the new opened application is also very high.. this continues until i reboot the system. There is single particular process occupy more cpu. All the processes cpu usage is little high than normal.. Any solutions?

• VMware + SQL Server - sqlserver.exe not using both CPU cores

  - by fistameeny

  Hi, I am working on a virtual machine that runs SQL Server Express (as part of Sage Line 50 Manufacturing). The details are as follows: Physical Server (host machine) - Intel Xeon Quad Core 2.1GHz - 4GB RAM - VMDK image stored on RAID-5 500GB SATA drives (7200RPM) - Running Ubuntu 10.04 Server 64 bit - VMware Server 2 Virtual Machine - Windows Small Business Server 2003 - Allocated 2 vCPU's and 2GB RAM - Using 100GB pre-allocated flat VMDK file The problem I have is that there is process that runs in SQL Server that is CPU intensive. On the old physical server that we migrated to the virtual machine from, this would utilise both CPU cores so the sqlserver.exe process would be running 100% on each of the CPU cores. On the virtual machine, it only seems to use one of the two CPU cores, meaning that the process is much slower to run. Question Is there a way to force SQL Server (sqlserver.exe process) to use both of the CPU cores, and distribute it's load between them? Is this a VMware setting that needs changing to allow processes to use both cores?

• High CPU Steal percentage on Amazon EC2 Instance

  - by Aditya Patawari

  I am experiencing high CPU steal percentage in a Amazon EC2 large instance. I know it means that my virtual CPU is waiting on the real CPU of the machine for time. My question is that what can I do to reduce this percentage and get maximum out of the CPU? Steal percentage is consistently at 20%. System load crosses 10 when this happens. I have checked memory and network and I am sure that they are not the bottleneck. Is that normal for such environment? Also are there any system level optimization techniques for reducing steal percentage form the virtual instance? avg-cpu: %user %nice %system %iowait %steal %idle 52.38 0.00 8.23 0.00 21.21 18.18

• Solaris 10: Identify a PID and the CPU it's running on

  - by Marcus

  I have multiple instances of a database running on a Solaris system. I'd like to prove that each database process is being handled by a different CPU. Essentially, I want to be able to do something like a ps -ef | grep <process_name> to get the PIDs and then run another command (if required) to identify the CPU... Is prstat able to do this? I'm making an assumption that as each database instance is started each one uses a different CPU. I'm not sure if I'm understanding this correctly... The reason I want to do this is because Sun hardware has slow CPU's, but lots of them. Therefore, to get the best performance out of it, I need to try and spread the load among CPU's... Thanks

• java memory allocation under linux

  - by pstanton

  I'm running 4 java processes with the following command: java -Xmx256m -jar ... and the system has 8Gb memory under fedora 12. however it is apparently going into swap. how can that be if 4 x 256m = 1Gb ? EDIT: also, how can all 8Gb of memory be used with so little memory allocated to basically the only thing running? is it java not garbage collecting because the OS tells it it doesn't need to or what?

• More interruptions than cpu context switches

  - by Christopher Valles

  I have a machine running Debian GNU/Linux 5.0.8 (lenny) 8 cores and 12Gb of RAM. We have one core permanently around 40% ~ 60% wait time and trying to spot what is happening I realized that we have more interruptions than cpu context switches. I found that the normal ratio between context switch and interruptions is around 10x more context switching than interruptions but on my server the values are completely different. backend1:~# vmstat -s 12330788 K total memory 12221676 K used memory 3668624 K active memory 6121724 K inactive memory 109112 K free memory 3929400 K buffer memory 4095536 K swap cache 4194296 K total swap 7988 K used swap 4186308 K free swap 44547459 non-nice user cpu ticks 702408 nice user cpu ticks 13346333 system cpu ticks 1607583668 idle cpu ticks 374043393 IO-wait cpu ticks 4144149 IRQ cpu ticks 3994255 softirq cpu ticks 0 stolen cpu ticks 4445557114 pages paged in 2910596714 pages paged out 128642 pages swapped in 267400 pages swapped out 3519307319 interrupts 2464686911 CPU context switches 1306744317 boot time 11555115 forks Any ideas if that is an issue?

Update Following the instructions of the comments and focusing on the core stuck in wait I checked the processes attached to that core and below you can find the list: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ P COMMAND 24 root RT -5 0 0 0 S 0 0.0 0:03.42 7 migration/7 25 root 15 -5 0 0 0 S 0 0.0 0:04.78 7 ksoftirqd/7 26 root RT -5 0 0 0 S 0 0.0 0:00.00 7 watchdog/7 34 root 15 -5 0 0 0 S 0 0.0 1:18.90 7 events/7 83 root 15 -5 0 0 0 S 0 0.0 1:10.68 7 kblockd/7 291 root 15 -5 0 0 0 S 0 0.0 0:00.00 7 aio/7 569 root 15 -5 0 0 0 S 0 0.0 0:00.00 7 ata/7 1545 root 15 -5 0 0 0 S 0 0.0 0:00.00 7 ksnapd 1644 root 15 -5 0 0 0 S 0 0.0 0:36.73 7 kjournald 1725 root 16 -4 16940 1152 488 S 0 0.0 0:00.00 7 udevd 2342 root 20 0 8828 1140 956 S 0 0.0 0:00.00 7 sh 2375 root 20 0 8848 1220 1016 S 0 0.0 0:00.00 7 locate 2421 root 30 10 8896 1268 1016 S 0 0.0 0:00.00 7 updatedb.findut 2430 root 30 10 58272 49m 616 S 0 0.4 0:17.44 7 sort 2431 root 30 10 3792 448 360 S 0 0.0 0:00.00 7 frcode 2682 root 15 -5 0 0 0 S 0 0.0 3:25.98 7 kjournald 2683 root 15 -5 0 0 0 S 0 0.0 0:00.64 7 kjournald 2687 root 15 -5 0 0 0 S 0 0.0 1:31.30 7 kjournald 3261 root 15 -5 0 0 0 S 0 0.0 2:30.56 7 kondemand/7 3364 root 20 0 3796 596 476 S 0 0.0 0:00.00 7 acpid 3575 root 20 0 8828 1140 956 S 0 0.0 0:00.00 7 sh 3597 root 20 0 8848 1216 1016 S 0 0.0 0:00.00 7 locate 3603 root 30 10 8896 1268 1016 S 0 0.0 0:00.00 7 updatedb.findut 3612 root 30 10 58272 49m 616 S 0 0.4 0:27.04 7 sort 3655 root 20 0 11056 2852 516 S 0 0.0 5:36.46 7 redis-server 3706 root 20 0 19832 1056 816 S 0 0.0 0:01.64 7 cron 3746 root 20 0 3796 580 484 S 0 0.0 0:00.00 7 getty 3748 root 20 0 3796 580 484 S 0 0.0 0:00.00 7 getty 7674 root 20 0 28376 1000 736 S 0 0.0 0:00.00 7 cron 7675 root 20 0 8828 1140 956 S 0 0.0 0:00.00 7 sh 7708 root 30 10 58272 49m 616 S 0 0.4 0:03.36 7 sort 22049 root 20 0 8828 1136 956 S 0 0.0 0:00.00 7 sh 22095 root 20 0 8848 1220 1016 S 0 0.0 0:00.00 7 locate 22099 root 30 10 8896 1264 1016 S 0 0.0 0:00.00 7 updatedb.findut 22108 root 30 10 58272 49m 616 S 0 0.4 0:44.55 7 sort 22109 root 30 10 3792 452 360 S 0 0.0 0:00.00 7 frcode 26927 root 20 0 8828 1140 956 S 0 0.0 0:00.00 7 sh 26947 root 20 0 8848 1216 1016 S 0 0.0 0:00.00 7 locate 26951 root 30 10 8896 1268 1016 S 0 0.0 0:00.00 7 updatedb.findut 26960 root 30 10 58272 49m 616 S 0 0.4 0:10.24 7 sort 26961 root 30 10 3792 452 360 S 0 0.0 0:00.00 7 frcode 27952 root 20 0 65948 3028 2400 S 0 0.0 0:00.00 7 sshd 30731 root 20 0 0 0 0 S 0 0.0 0:01.34 7 pdflush 31204 root 20 0 0 0 0 S 0 0.0 0:00.24 7 pdflush 21857 deploy 20 0 1227m 2240 868 S 0 0.0 2:44.22 7 nginx 21858 deploy 20 0 1228m 2784 868 S 0 0.0 2:42.45 7 nginx 21862 deploy 20 0 1228m 2732 868 S 0 0.0 2:43.90 7 nginx 21869 deploy 20 0 1228m 2840 868 S 0 0.0 2:44.14 7 nginx 27994 deploy 20 0 19372 2216 1380 S 0 0.0 0:00.00 7 bash 28493 deploy 20 0 331m 32m 16m S 4 0.3 0:00.40 7 apache2 21856 deploy 20 0 1228m 2844 868 S 0 0.0 2:43.64 7 nginx 3622 nobody 30 10 21156 10m 916 D 0 0.1 4:42.31 7 find 7716 nobody 30 10 12268 1280 888 D 0 0.0 0:43.50 7 find 22116 nobody 30 10 12612 1696 916 D 0 0.0 6:32.26 7 find 26968 nobody 30 10 12268 1284 888 D 0 0.0 1:56.92 7 find Update As suggested I take a look at /proc/interrupts and below the info there: CPU0 CPU1 CPU2 CPU3 CPU4 CPU5 CPU6 CPU7 0: 35 0 0 1469085485 0 0 0 0 IO-APIC-edge timer 1: 0 0 0 8 0 0 0 0 IO-APIC-edge i8042 8: 0 0 0 1 0 0 0 0 IO-APIC-edge rtc0 9: 0 0 0 0 0 0 0 0 IO-APIC-fasteoi acpi 12: 0 0 0 105 0 0 0 0 IO-APIC-edge i8042 16: 0 0 0 0 0 0 0 580212114 IO-APIC-fasteoi 3w-9xxx, uhci_hcd:usb1 18: 0 0 142 0 0 0 0 0 IO-APIC-fasteoi uhci_hcd:usb6, ehci_hcd:usb7 19: 9 0 0 0 0 0 0 0 IO-APIC-fasteoi uhci_hcd:usb3, uhci_hcd:usb5 21: 0 0 0 0 0 0 0 0 IO-APIC-fasteoi uhci_hcd:usb2 23: 0 0 0 0 0 0 0 0 IO-APIC-fasteoi uhci_hcd:usb4, ehci_hcd:usb8 1273: 0 0 1600400502 0 0 0 0 0 PCI-MSI-edge eth0 1274: 0 0 0 0 0 0 0 0 PCI-MSI-edge ahci NMI: 0 0 0 0 0 0 0 0 Non-maskable interrupts LOC: 214252181 69439018 317298553 21943690 72562482 56448835 137923978 407514738 Local timer interrupts RES: 27516446 16935944 26430972 44957009 24935543 19881887 57746906 24298747 Rescheduling interrupts CAL: 10655 10705 10685 10567 10689 10669 10667 396 function call interrupts TLB: 529548 462587 801138 596193 922202 747313 2027966 946594 TLB shootdowns TRM: 0 0 0 0 0 0 0 0 Thermal event interrupts THR: 0 0 0 0 0 0 0 0 Threshold APIC interrupts SPU: 0 0 0 0 0 0 0 0 Spurious interrupts ERR: 0 All the values seems more or less the same for all the cores but this one IO-APIC-fasteoi 3w-9xxx, uhci_hcd:usb1 only affects to the core 7 (the same with the wait time of 40% ~ 60%) could be something attached to the usb port causing the issue?
