High CPU usage for long periods of time

Has anyone had any problems with running a job for more than an hour that pushes most of the CPU cores to 100% usage? I'm planning on making some animation, and with each frame taking about 5-7 minutes each, a single second of animation is going to come in around 2 hours 20 minutes or worse. For a 10 to 20 second clip that could easily cause the CPU to run at 100% for almost 12 hours or more. I've never had anything run that long on any system I've owned and I'm not sure if it's going to overheat the box, or if it's hard on the CPU to run that long. Anyone have any experience with this on a desktop system (for the record it's an 8 core MacPro)?

You should definitely take a test run monitoring CPU, disk and case temperature. Desktop systems often don't have enough airflow. Nothing that can't be fixed with another fan or two. Oh, and make sure the room the box stands in is big enough to cope with it. I'm running Folding at Home permanently on 3 of 4*2(HT) cores.

I used to work a 3d animation studio. We didn't have a proper render farm, so many o' times during the night we'd have all the machines at work render scenes for commercials. I never had any problems with the machines overheating. Just so as long as they are properly cooled to begin with. I mean I'm sure if you did this for like 5 months in a row you'd hit a snag, but I doubt it would be too much to overcome. That being said, a 100+ machine render farm would totally rock. Too bad I haven't won the lottery yet.

And do we get to see the animation when it's done? :-\

Nope, but then again I have water-cooling[^] :cool: I think the 8core macs are the same as the i7 900 series, so your CPU can handle temps up to 99 deg C (not that you want it that high, just saying). Running continuously, I would not feel happy if it was over 80 deg.

I have seen that before, but it sure seems like a lot of hassle (and a lot of other little issues).

I had a rig like that up and running for about 6 months before the power went out (in the house) one night...it never worked again and I've never spent the time to fix it... just drained it, put the mineral oil back in the jugs and it is now boxed up in the closet. http://www.kinar.net/computer/[^] The heat stayed pretty constant in the tank even when the machine was under load.

Whether its going to be OK or not depends on the system and the ambient environment. Laptops are typically the worst, but not all, and there's some poorly designed and cooled desktops out there too. Given multicore chips are still fairly new and mostly underutilized, I wouldn't just assume the system cooling was sufficient for extended runs of such a CPU intensive application, not even on a Mac. About all you can do is to set up a temperature monitor to warn you if it gets too hot and hope the sensors are in the needed places. Some CPUs have internal temp sensors built in and will protect themselves from overheating, I don't know if that's Mac's CPU has that feature.

Heating and cooling cycles will wreck a CPU over time. Too much heat will too but most systems have safeguards in place to stop that from happening (unless disabled). I have run scientific apps that hit all cores at 100% for days and haven't had any problems. I'm not sure about Macs, but they're Intel now anyways and are basically PCs with a MAC OS and proprietary drivers. Just make sure that there is adequate ventilation around the computer so that it's not sucking in hot air. The internal temp should plateau at a certain level and stay there for the duration of the run (+/- a degree or two).

so do I. Sadly the gap between top end air cooling and water cooling with a 2x120 rad has been shrinking rapidly. My next upgrade is probably going to be a 3x120 rad and a bigger case; currently I'm thinking a mountain mods u2-ufo[^].

That case is a monster :) I also feel a 2x120 rad is just a little too small for an i7. At least I can make space to add another 2x120. Anything larger, and I would need to buy something bigger too. I really like that Silverstone TJ07 though, but it is not available locally, and shipping would be a killer from anywhere else.

I've been running Folding/SETI/MilkyWay@Home for years straight now. 100% all the time
// Steve McLenithan
I too have been running SETI@Home for years, so 100% all the time here too. I did have my fan turned down too low for a while and I was getting some unexpected freezes every now and again, but after turning up the fan speed it has been fine ever since.
