I have seen such behavior when the power supply wasn't up to the job. The voltages fail to stabilize and the system shuts down.

I would've guessed at 32 cores, as the CPU time is more or less exactly 32 times the wallclock time. The system time and the user time sum to form this figure, and effectively are broken down as time doing kernel operations, and your application code (and the non-kernel portion of what it's calling).

The "CPU time" is the total time used by the program on all CPUs ("CPU" here means "core" if you have hyperthreading disabled; it means "logical processor", if you have hyperthreading enabled). Thus on a system with four cores, HT disabled, a program that runs for 30 seconds of wall-clock time could theoretically use up to 120 seconds of CPU time. As ...

The number you see in that column doesn't actually refer to the number of CPUs in use. If you look at the Microsoft page that explains the column headers (look for the heading titled "CPU Usage"), you can see that the number actually represents: The percentage of time that a process used the CPU since the last update This is the reason that the sum of ...

If you run top -u in a Terminal, it will show you what processes are running, sorted in descending order by CPU usage. This should reveal to you who the culprit is (ruby or otherwise). You should see the process ID (PID) of that process in the top output. Then you can quit top (hit q) and do kill pid where pid is the pid of what you want to kill.

This can be done by capturing a xperf trace and opening it with Windows Performance Analyzer (WPA.exe) from the Windows Performance Toolkit, here you can add a column CPU to see which CPU (Core) the process is running:

I'm not sure about your level of expertise on Computer Architecture, however the Core i5 you've mentioned here implements a form of multi-threading known as Simultaneous multithreading (SMT). Intel's trademark for their implementation of SMT is hyperthreading. Apart from SMT there are other forms of multi-threading, temporal multi-threading being one. For ...

To answer my own question: Django's dev server checks all Python source files periodically for changes. Setting the option --noreload prevents this auto-restart mechanism, which also reduces the idle load to zero. Apparently, auto-reload on Python 3 is less efficient. Using pyinotiy is a solution for Linux to also prevent this overhead: ...

Requested in 2005: I am very impressed with the features integrated in Process Explorer but would like to see an option to display each process CPU affinity in the main window as a column toggle. No response. Requested in 2007: Thanks for superb utilities. My request is to add a column option to process explorer to display CPU affinity. That's it. ...

Have you tried replacing your hard drive? This was happening to me with a failing hard drive - my gaming was s l u g g i s h. 60fps all the time, but drops to 0 for a while. So, I replaced my HDD with an SSD and haven't looked back since.

A Video card does affect video playback... but, your issues were probably more down to CPU and drive I/O. If you had a 10Gb file, I am guessing it was most likely 4k or uncompressed 1080P (or compressed/high bit rate). A Celeron is typically a low end processor, and with low end processors come low end 5400 RPM (or god help you, 4800 RPM) hard drives, ...

Maximum CPU utilization is not per se a major objective of scheduling algorithms. It is just a side effect of an obvious scheduling algorithm objective which is to keep the runnable processes waiting queue as short as possible.

You can record the frequency of your CPU and then see how turbo boost behaves. I would also be interested in that :) Check my answer here (the last picture) how to record the frequency using perfmon There is something odd with my CPU

If it's the same socket and it is, socket 775 it will fit. The cooler you currently have is noisier 32.2 ~ 41.1 dBA but I think it cools better because it moves up to 61.78 cubic feet of air per minute. The fan you want to buy has noise level <22.2 dBA and moves 49.37 CFM but it doesn't mean it will be cooling worse, that needs to be put on the test.

Pretty sure if you're running discreet and dedicated nvidia cards you should be able to configure bumblebee: https://wiki.ubuntu.com/Bumblebee Baring that there you can also write your own xorg.conf files to try to accomplish what you're asking for. Also, of you already have it or the money, VMware Workstation 11 has made pretty good progress with video ...

It's a matter of priorities. I don't mean thread or process priorities. I mean - what's more important? Getting work done, or saving power? If getting work done is more important - and btw, in what you described, that is apparently the case - then if there's work to do, you want the processor doing that work. An idle processor is a wasted processor, just ...

It usually shows an internal frequency divisor's value, not the actual frequency feeded out : there's no frequency meter is built-in in CPU and motherboard. It's actually a shame :(

Check your code for While-sleeps and replace them by actual sleep + check your kernel config.

Perhaps you could, but it wouldn't make any sense. With the two systems having such massive latency between them and no hardware mechanisms for fast memory coherence, it wouldn't make sense to try to combine them in that way. You can't use another person to let your brain control two more arms. You have to let their brain control their arms because your ...

Operating system level? Very difficult, but it can be done. A more practical solution lies in clustering based on application and this would typically be done on a server level; also known as a sever farm. For example, having a load balancer sit in front of multiple Apache severs to spread traffic load. Or perhaps a shared Mongo cluster. Or even MySQL with ...

Possible but not easy... I think this question and answers from this link will be helpful to you. It would be easier to get a motherboard that supports the CPU's in question and has dual CPU ports but again its an expensive route, esp considering the cost of quad core machines nowadays.

I happen to have the same CPU as you and I recommend you to use some more monitoring software to detect top fan speed and see throttling. HWmonitor is great because it shows many things and also minimum and maximum value it measured. To make a graph of your CPU frequency during a game or something just use that great windows tool called perfmon ;) Press ...

Generally speaking todays motherboards have 2 of the PWM headers for the CPU and any secondary cpu fan item (cpu-opt), these 2 connections are best used with PWM actual fans with 4 pin connections. Because the method of control is via PWM, the feed voltage is the same, so a 3pin fan will run at full speed. It is true that a 4pin actual PWM connection ...

Probably motherboard or power supply. Processors rarely broke. PC computers are not made wtih diagnostics in mind. So only way to tell what part is defect is to test every part on working system. So motherboard model and PSU manufacturer and model? Also check if motherboard condensators are OK.

I recently got a laptop with a Atom Z3735 processor and 2GB RAM (an Asus X205TA), and here's what I've found: In Internet Explorer using Youtube's HTML5 player, I was able to play a 60fps 1080p video, and it certainly looks smooth as silk to my untrained eye. Unfortunately, I could not get Youtube's "Stats For Nerds" feature to actually display the FPS; it ...

It's a good idea to set the ram speed and timings manually. It has been my experience that some motherboards simply don't like XMP settings and try to overclock your CPU to get the RAM to run at it's the XMP defined speed/timings. You will need to refer to your motherboard's manual on how to set the memory speed/timings manually. You will also need to ...

Direct Memory Access (DMA) is the missing piece of your puzzle. DMA lets I/O device controllers directly read and write memory without CPU intervention. Without DMA, a buffer may still be employed as the data needs to live somewhere while it is being retrieved and it may be desired to only give data to the requesting program if the I/O completes ...

There is nothing wrong with that bus speed when looking at the multiplyer - 133.6 x 23 = ~3.06Ghz which is the rating of the i7 950. Without know what graphics card you have, or what game you are playing and seeing the requirements of it, it is too hard to help you. The average Thermal rating for that CPU is 67.9c, so, if you are reading a temperature of ...

Your CPU is likely throttling due to excess heat buildup. Even if you have a proper cooling solution, it could be improperly mounted or the connection might have loosened over time. So the first step in trying to fix this is removing the heatsink assembly and removing all thermal paste remains from both CPU and cooler (carefully, of course). After that, ...

You want the coldest air possible being pushed or pulled through the heat exchanger for optimal convection-cooling. That air is found outside the case, typically at the front. I would leave the fans the way you have them. If you want lower temperatures, you could fabricate or purchase a shroud that would go from the front of the case to the CPU fan, or look ...

Since you tried a new mobo and it stil doesnt work, the CPU is almost certainately fried. The mobo would boot into the BIOS is a working CPU was installed. Short circuiting is known to provide heavy damage to electronic chips like CPUs.

Depending on what shorted out, it’s very possible some not-so-good currents reached your CPU and fried it. Seeing how you already changed just about everything (except RAM, I guess), and your CPU doesn’t warm up, it’s probably totally gone. By the way, that PSU of yours can power two of your computers at the same time. ;)

Coffee is not the worst substance to get on a PC, and you might be able to salvage most of it. Unplug the unit from the wall and remove the coin batteries from the clock. Wait a few minutes for the capacitors in the power supply to bleed down before the next step. Wash all boards and cables in distilled water (if you have friends in a chem lab, beg some ...

Typically, the number of cores should be listed where you are looking.

You will need to search for Processor inside the MSINFO application. If MSINFO32 doesn't report a number of cores and logical processors, then it's running on a single processor. Doing a little googling the only thing I could find close to your named processor above was a Celeron chip which would only = 1 core. I was not able to find the exact x86 ...

Not directly. More memory sticks = more heat generated. If the casing's airflow is not good enough, then that will drive the CPU's operating temperature = higher chance of failure. On the other hand, the errors you see might be caused by many factors: Bad memory stick Local overheating due to obstructed airflow Corroded contacts on one (or more) of the ...

It is highly unlikely that 4 sticks of memory will make the CPU go bad [ any more then 1 or 2 sticks would ] - infact, if you look at really powerful systems they typically have lots of memory banks. It sounds simply like (at least one of) your memory sticks is faulty.

The reason is because the cpu does not address a whole page at a time; it addresses each and every individual byte. The page is simply the unit that the is used to allocate memory and set permissions on it. Also that wikipedia article has an error: disk IO is not done in page units either; it is done in sectors, which conventionally is 512 bytes.

In the old days mainframe memory was described as so many words. Where words were defined by the hardware ( 18,20,30,32,60,... bits). When minis and PCs arrived, memory was described by bytes ( 4K all the way to 64K ). Now we have a lot more memory and it is still described by the number of bytes. What you say is true and pages may be a better method of ...

Software RAID1 cpu requirements are pretty much none. You won't notice any problems. It's most likely that you will encounter disk IO problems first (depending on the usage) due to RAID1 needing to write to both disks before acknowledging the IO. Other than that I believe that especially for home use you won't notice any performance issues related to ...

According to the specs here and here, the maximum RAM size is 8GB, with 2 DIMM slots. What they don't tell you is what the maximum DIMM size per slot is. In the manual though it states (pg 1-13): You may install 512MB, 1GB, 2GB, and 4GB unbuffered non-ECC DDR3 DIMMs into the DIMM sockets. So it appears that the maximum stick size per slot is 4GB ...

The advantage of an unlocked processor is that you get fine grained control over the clock multiplier. The clock multiplier is only one of several variables adjusted when practicing the art of over clocking. Years ago, before cpu manufactures locked multipliers, malicious people would buy cheaper clocked CPUs, change the multiplier and sell the computers ...

The CPU fan might be spinning, but a spinning fan is useless unless it has good thermal contact with the CPU. Otherwise it might be as helpful as a spinning fan on your desk (outside the laptop). If you removed the fan to repair it then reattach it properly. That is with the right thermal paste or a good thermal pad. If you did not remove the fan then ...

Cooking oil is a very wrong choice, also you might have damaged temp sensor. Change the fan to a comletely new one and do not forget to apply thermal paste.

In this generation's Xeons, the first digit in the Product Family section of the processor model/SKU number (i.e.: 16xx, or 24xx) tells you how many processors can be used on one motherboard/node (aka "Wayness"; as in 1-way (single CPU), 2-way (dual CPU), 4-way (quad CPU) or 8-way (octa CPU) physical-CPU multi-processing).

you mean the room temperature? You might have a sensor that's relatively cool on the motherboard somewhere, but the best you'd get is an "inside the case" temp, almost always warmer than the room. I haven't heard of any onboard "remote sensors" that you could stick on the outside of the case, or even out the window (but that would be fun). There's probably ...
