My 27" 8-core imac, i7, 3.8ghz, AMD radeon pro 5500, 40 GB RAM 512 GB storage,

keeps screaming in agony.

But never stuttered.
Never lagged.
Never glitched
Never failed
Never ran out of memory

I can just hear how hard the the ventilation was going. It was getting loud.

I touched its ass from behind. It was heated up and there was lots of dust from the holes

This has been going on for several days but i ignored it knowing what kind of a beast machine i have (big mistake)

Intellj popped up notification to disable hints in order to improve cpu usage performance.

Immediately it struck me. Hold on lemme check the activity monitor stats and find out why my imac has been screaming for days

Turns out intellj is using over 1090% of my fucking CPU?????

THAT SHIT U SEE ON THE IMAGE WENT ABOVE 1100% OF CPU USAGE AND IT WAS ONLY 1 PROCESS CAUSING IT - INTELLIJ

WHAT???

    have you thought of buying a more powerful iMac? This one seems to be not good enough for IntelliJ *sarcasm*

    You see, this is how awesome intellij is:
    It utilizes more processing power than your machine has to offer. It’s not limited by hardware!

    Is the max 1600% since the cpu can run 16 threads?

    The noise just means that the cooling system sucks.

    @electrineer never thought cpu usage can go beyond 100%

    @b2plane And suddenly the rant and screenshot start to make sense...

    Yeah, 100% is one hyperthread and how much compute cycles that represents depends on the current clock speed of the core running that hyperthread. So if it slows down because of heat or being idle, 100% means less compute cycles than when it is running at full speed. Traditionally, the percentages for each hyperthread are just added together for the whole CPU percentage.

    @Oktokolo is intellij mining bitcoin on my machine or whats going on???

    If a 16 core machine is screaming using only 2/3 of available processing power, that ain't a problem with the process being run. That's a you problem.

    I wouldn't know since crapple, but seeing Windows reports CPU usage as percentage of total resources (eg, 12.5% for one core out of eight maxed out), it's also perfectly reasonable to show percentages per core (or hardware thread if HT) in which case, that percentage would be entirely normal.

    Intellij does make heavy (and mostly sensible) use of multithreading, so it wouldn't be surprising.

    @b2plane It's a fat IDE. If it keeps using that much compute when being idle, you should invalidate the cahes and restart it. Because normally, it's barely noticable when idle after it did all the indexing and analyzing which are the reason for using an IDE in the first place.

    @Nanos I always prevent the fan from spinning when blowing or brushing off the dust.
