Is it bad for Fans and CPU?

Hey guys,
     I'm currently using a mid-2012 15" Retina MacBook Pro with 2.6 GHz + 16GB of ram. I've been really wanting to use the SETI home application. This application basically uses your CPU's power and GPU's power at 100% (unless you're doing something else)
     Obviously, with CPU + GPU at 100%, the fans are going to kick on. My question is, is it bad to run the computer at 100% capacity for GPU and CPU? Will this damage the fans over time?
     I'm talking about leaving the computer on for hours at a time and letting it do its thing. There's a very good chance it will be hot for several hours with the fans on for several hours.
     On a previous Retina MacBook Pro I owned, I tried this and processor reached 212 degrees F (boiling point for water) and 180 F for GPU. Fans were on all the time.
     Is this bad and how bad is it?
Thanks a lot.

You're doing what some could call a burn-in run. Where you get everything hot and sustain that usage for long periods of time. The Mac can handle that, I have used older MBP's for the IT field and they had to process tons of data, they got hot, but I let them cool down at night.
The fans won't get damaged, its a solid-state motor, unless you stick something in the fan...
The thermal paste on the CPU/GPU may degrade quicker though. That is my one hesitation about dedicating this machine to that.
I should note, that the heat and the power consumption is going to take it's toll on your electric bill too.
85 watts * ~6 run hours per day = about $40 more on the bill.

  • Hyper-V Resource Pools for Memory and CPU

    Hi all,
    I'm trying to understand the concepts and details of resource pools in Hyper-V in Windows Server 2012. It seems as if there is almost no documentation on all that. Perhaps somebody can support me here, maybe I've not seen some docs yet.
    So far, I learned that resource pools in their current implementation serve mainly for metering purposes. You can create pools per tenant and then group VM resources into those pools to facilitate resource metering per tenant. That is, you enable metering
    once per pool and get all the data necessary to bill that one customer for all their resources (without metering individual VMs). Is that correct?
    Furthermore, it seems to me that an ethernet pool goes one step further by providing an abstraction level for virtual switches. As far as I've understood you can add multiple vSwitches to a pool and then connect a VM to the pool. Hyper-V then decides which
    actual switch to use. This may be handy in a multi-host environment if vSwitches on different hosts use different names although they connect to the same network. Is that correct?
    So - talking about actually managing that stuff I've learned how to create a pool and how to add VHD locations and virtual switches to a pool. Enabling resource metering for a pool then collects usage data from all the resources inside that pool.
    But now: I can create a pool for memory and a pool for CPU. But I cannot add resources to those. Neither can I add a complete VM to a pool. Now I'm launching a VM that belongs to a customer whose resources I'm metering. How will Hyper-V know that it's
    supposed to collect data on CPU and memory usage for that VM?
    Am I missing something here? Or is pool-based metering only good for ethernet and VHD resources, and CPU and memory still need to be metered per VM?
    Thanks for clarification,

    Thank you for the links. I already knew those, and unfortunately they are not matching my question. Two of them are about Windows Server 2008/R2, and one only lists a WMI interface. What I'm after is a new feature in Windows Server 2012, and I need conceptional
    information.
    Thanks for the research anyway. I appreciate that a lot!
    In the meantime I've gotten quite far in my own research. See my entry above of January 7th. Some additions:
    In Windows Server 2012, Hyper-V resource pools are mainly for metering purposes. You cannot compare them to resource pools in VMware.
    A resource pool in Hyper-V (2012) facilitates resource metering and billing for VM usage especially in hosting scenarios. You can either measure resource usage for single VMs, or you can group existing resources (such as CPU power, RAM, virtual hard disk
    storage, Ethernet traffic) into pools. Those pools will mostly be assigned to one customer each. That way you can bill the customer for their resource usage in a given time period by just querying the customer's pool.
    Metering only collects aggregated data with one value per resource (i.e. overall CPU usage, maximum VHD storage, summed Ethernet traffic and so on). You can control the time period by explicitly resetting the counter at any given time (a day, a week, a
    month or what you like).
    There is no detailed data. The aggregate values serve as a basis for billing, not as monitoring data. If you need detailed monitoring data use Performance Monitor.
    There is currently only one type of resource pool that adds an abstraction layer to a virtualization farm, and that is the Ethernet type. You can use that type for metering, but you can also use it to group a number of virtual switches (that connect to
    the same network segment) and then a VM connected to that pool will automatically use an appropriate virtual switch from the pool. You need no longer worry about virtual switch names across multiple hosts as long as all equivalent virtual switches are
    added to the pool.
    While you can manage two types of pool resources in the GUI (VHD pools and Ethernet pools) you should only manage resource pools via PowerShell. Only there will you be able to control what happens. And only PowerShell provides a means to start, stop, and
    reset metering and query metering data.
    The process to use resource pools in Hyper-V (2012) in short:
    First create a new pool via PowerShell (New-VMResourcePool). (In case of a VHD pool you must specify the VHD storage paths to add to the pool in the moment you create the pool.)
    In case of an Ethernet pool add existing virtual switches to the pool (Add-VMSwitch).
    Reconfigure existing VMs that you want to measure so that they use resources from the pool. The PowerShell
    Set-VM* commands accept a parameter -ResourcePoolName to do that. Example:
    Set-VMMemory -VMName APP-02 -ResourcePoolName MyPool1
    Start measuring with Enable-VMResourceMetering.
    Query collected data as often as you need with Measure-VMResourcePool.
    Note that you should specify the pool resource type in the command to get reliable data (see my post above, Jan 7th).
    When a metering period (such as a week or a month) has passed, reset the counter to zero with
    Reset-VMResourceMetering.
    Hope that helps. I consider this the answer to my own question. ;)

  • Badi for searchterm and lifecycle

    Hi,
    When an account is created then the value in searchterm is checked against a table .If the value in searchterm is present in the ztable and our lifecycle value is customer then that account is created otherwise an error message is to be returned on the UI.
    For implementing the above condition we have to implement BADI's for both the fields?
    I am able to find the BADI for searchterm check but i am unable 2 find a BADI for lifecycle field.
    Please help.
    Regards
    Shilpi

    I think you can use the badi 'BUPA_FURTHER_CHECK'. This badi is called in the function module 'BUPA_CENTRAL_CHANGE'.
    In general, the BP search term ('BU_SORT1' or 'BU_SORT2' in the table 'BUT000' is contained in the root object 'BuilHeader' of BOL model.This object is controlled by the class 'CL_BUPA_IL_HEADER' (#1). If an user changes the BP data, the method 'Modify' will be called. And also, if the user saves the BP data, the method 'SAVE' will be called.
    The above badi is called during the processing the 'modify' method.
    If this badi does not meet your requirment, I think you should also consider to use the following transaction (#2). In this transaction, you can replace the standard processing (ex. cl_bupa_il_header) with your own logic.
    Hope this helps.
    (#1) You can find the standard definition in the table 'CRMC_OBJIMP_BUIL'

  • Menu exit or BAdi for IW28 and IW65

    Dear Experts,
    Please provde Menu exit or BAdi for IW28 or IW65, to calling customized program.
    i.e.  have one 'Z' Program, i want to cali that from IW28 and IW68 using menu option.
    Regards,
    venkey

    Venkey,
    Here are some options...
    IW28: If you are in ECC 6.0 with enhancement pack 3 then you could enhance the report using BADI BADI_EAM_RIQMEL20_FCODE_CUS1 To create a custom function code. You could also consider copying the report and creating a  new report. You could also use the GuiXT tool to create a push button on the output screen and call the Z report.
    IW42 and IW65 : There are no standard user exits to do this, You will have to copy and change the program. You could also use GuiXT tool to create a Push button for this transaction.

  • Version Mismatch for Kernel and CPU after 10.6.4 update

    I had a kernel panic in both Mac Pro and MacBook Pro after a usually no-brainer software update OS X 10.6.4....I tried all of the shortcuts (zapping PRAM, booting from other drives, safemode, etc) and I get the dreaded gray screen and restart message immediately,,,what can I do short of purchasing a new board for each machine?
    I did disk verification and repairs via target disk mode from a third laptop, but the pro macs never get past the grey screen in order to give me the chance to update! The screen text says:
    "panic(cpu 0 caller 0x2x096e6) Version mismatch between Kernel and CPU PM"@/Source Cache/...
    Debugger called: <panic>"
    What can I do to GET PAST the "version mismatch" and "ned to restart" screen to be ABLE to update?

    Just tried installing the 10.6.4 update on my iMac i5. It began the usual shutdown, and I was expecting the install to begin. That never happened. 10 minutes went by at least. I forced it to shut down, and now it won't boot. Same as the OP - "Version mis-match between Kernel and CPU PM"
    There is no option to boot from anything else, either. The machine won't boot from an original install CD, or from an install image I keep on USB. I tried zapping PRAM, and resetting SMC. At this point, I consider it bricked. Fortunately, I have a reasonably recent TM backup.
    Won't have time to take it in until Monday. Sure hope someone has some insight before then.

  • EXIT/BADI for ME31L and ME31K for changing Incoterms in header and item

    Hi All,
    I am facing an issue in ME31L,ME32L transactions.
    In vendor master , incoterm is maintained .So whenever a PO is created with particular vendor, the same incoterm(EKKO-INCO1& EKKO-INCO2) will get defaulted into PO as well. Now i need to change the incoterms2 on basis of some logic, but i was not able to find the correct BADI/EXIT to do these changes.
    This relation can be seen in vendor master partner profile.
    SO if I create a PO/SA with a vendor and goods supplier is different the incoterm from vendor is getting defaulted there, not from goods supplier .
    So am looking for any EXIT/BADI which will enable changing of Incoterms2 based on the incoterms1 value.
    Thanking you in advance.
    satheesh

    HI Sharma,
    Thank you for your response.
    This particular BADI ME_PURCHDOC_POSTED is getting triggered when i am creating a SA in ME31L but when I am changing the values in the BADI that is not getting updated on the screen.
    thanks,

  • What kinda screensaver is good for TFTs and CPU?

    I read somewhere that for TFTs screensavers that turn your screen black aren't the best thing (they don't save energy, they use it even more). - Don't ask me for any proofs.
    So, which kind of screensaver saves most energy and uses my iMac TFT the least?
    Thanks a lot
    Peter

    Peter,
    The best kind of screensaver for TFT's is display sleep.
    Screen Savers: Using With Liquid Crystal Displays"Putting the computer to sleep or shutting it down when it won't be used for extended periods is preferred to a screen saver. The Energy Saver control panel has a setting for display sleep that is applicable to both PowerBook and stand-alone flat panel displays such as the Apple Studio Display and Apple Cinema Display.";~)
