OT- Computer Issue?

Hi Everyone.

I think that I might be experiencing some sort of computer issue but im not certain. Im not really tech savy so please bear with me. Last night I was messing around in photoshop when I got an error that said
I was low on hard disk space or something like that. Ever since then ive seen strange spikes in the usage numbers in the task manager. Usually I keep the task manager open when im rendering to see if a scene is impacting the cpu (iray renders). Lately, the Disk % has been wildly fluctuating. Opening daz can cause the disk % to jumpt to 50, loading a G3 character, 25 percent or so, all sorts of tasks just cause the percentage to climb.

Did something break?

Thanks.

    No. CPU spikes are typical on heavy i/o operations like reading from disk to memeory.

    Yah, I see cpu spikes occasionally, that wasnt the one i was refering to. It seems that the wierdness may have been caused by a windows defender update though. The wierdness seems to be dropping back to normal levels.

    Well lots of computer activities cause CPU usage spikes. Rendering in DAZ Studio, rendering in Blender, doing a file system find, and so on.

    Ok, sorry, got confused. So should I recieve another warning about hard disk space, is it talking about the overall storage space on my c drive?

  • nonesuch00nonesuch00 Posts: 18,784

    The error/warning message will tell you which drive is low on space.

    I had computer slowages yesterday and this morning. frown Then I discovered that Microsoft had force fed me one of their 2nd Tuesday of the month updates that was now ready to be installed when I attempted to shut it down.  I don't know exactly what it does during an update cycle but I've noticed that my system gets sluggish when it's analyzing or downloading big updates. enlightened My system is OK now that I've completed the reboot after the update. indecision

    Check your "My Computer" or the Win10 equivalent "This PC" folder to see how full your disks are.

    ...the interesting part of this is when I am working on a scene (during which Daz only uses one core) I sometimes see high core usage on all 8 threads even when the Daz is the only programme I'm running.

    Also getting a fair number of "not responding" messages lately, both in FF, and Daz.

    Bandwidth throttling by the ISP?

    ...no this, happens when I'm working offline as well.  In the case of FF, if it were bandwidth throttling I'd just get perpetual swirlies until a connection was made (or it would timeout).  That message is a local system one.

    I always see the "not responding" message in Daz. No clue why daz cant simply load a file like every other program available.

    The biggest mystery I have with my computer and daz is that depending on the scene, the cpu will spike to 100% before the memory use gets to even 50%. Again, not technically inclined and the only evidence I have of this is the task manager readings, but shouldnt the memory use peak before the cpu kicks in like that?

    It's normal - it Windows that generates that message when a process takes a long time to finish. Quote:

    "An application gets the events from a queue provided by Windows. If the application doesn't poll the eventqueue for a while (5 seconds), for example when doing a long calculation, then Windows assumes that the application is hung and alerts the user ["Not Responding" message]. To avoid that, applications should push expensive calculations to worker threads or split up processing and make sure the queue gets polled regularly."

    Pushing the process to another thread or splitting it may prevent the message from showing, but if the process (like loading a file) needs to be finished anyway before any other process can be started, and it normally doesn't take too long (like 8-10 seconds) there's technically not much point in doing it, it will usually just make the code more complex. So many programmers just choose not to do it in that case.,

    It's a problem though when a process may take so long that the user don't know if the program has crashed or is just being busy, if that's likely to happen a separate thread and a progressbar or some other feature indicating that it's still running should be used.

    As for CPU and memory, though they interact in different ways they are independent as such, you can easily have the CPU run at 100% while using only a little memory, or use a lot of memory and only a little CPU.

    ..yeah, when I load scene in Daz it I'll get a "Not Responding" message for several minutes. the viewport in one display and sometimes the tabs in the other go blank white when this happens which is almost blinding.

    One of my RPG utilities does this but only when the character file becomes fairly large over time (I'll have to write about process pushing to the developers as it is an open source programme).

    So, not daz, windows. Ok.

    For the cpu/ memory use, I thought that iray was only supposed to fall back on the cpu when it ran out of memory, vram as I believe ive seen it called? I assumed that that is what was happening when the cpu spiked, my old card was running out of vram...

    Well both, really - DS behaves in a certain which triggers a message from Windows.

    OK, wasn't aware of the context, I talked about CPU and system RAM in general, not about Iray and VRAM.

    But CPU usage can very well be high, like 70-90%, when doing Iray/GPU rendering, not sure what it's actually doing in that case though. How high depends on how fast the CPU is and different things like CPU settings on the Iray Advanced tab, how fast the GPU/card is etc., I assume.

    Hmmm, so, BLACK MAGIC!!! in other words! devil

    Ok. Maybe I should take a peek at my iray settings. Perhaps the answer L.I.E. s within (chuckle, chuckle).wink

    ....I have it occurring when loading a scene and even when changing items around in a scene in OpenGL mode.

    If you scene renders black, it may be... wink
