Re: Fun with Linux software RAID

Do any of the SMART attributes look funny? Is the firmware on the drive up to date? I've seen drives do some awfully funky things over the years and sometimes a power cycle of the drive would resolve any issues.

Dude, there's no such thing as buying a bad SVS subwoofer. :)

Re: Technology purchasing and "moments of weakness"

I tend not to impulse purchase things I haven't thought about before...but sometimes I'll spend 10 hours researching something, decide I don't really need it, and then buy it on a whim 3-4 months later. Generally not with computer hardware, but with car parts, audio gear, and gadgets. My ability to ...

Re: How do you actually run games on high-spec monitors?

I guess I oversimplified a bit (I was tired and in a bad mood before) - I lucked out with my TV/monitor because it scales a 1080p "PC" input without any interpolation. I just set my native output to 1920x1080 on my desktop and the monitor doesn't do any interpolation. I thought this was pr...

Re: Kampman wants 32 Core benchies? Here are a few!

That's what support contracts are for ;) There's no HPC in our environment (small-mid size University) but I can't imagine there's a hardware issue that can't be solved by vendor support given proper specification of hardware for the intended workloads. Um, no. There are always support contracts (n...

Re: Kampman wants 32 Core benchies? Here are a few!

Utilization, as a metric of efficiency, is largely irrelevant to this discussion, IMHO. Customers of this size, with these type of workloads, do not care if their clusters have 3% efficiency or 99%. Actual, measurable performance is what matters most. If one solution outperforms another and costs a...

Re: How do you actually run games on high-spec monitors?

Something I've always wondered about is how 1080p looks on a 4K screen? e.g. If I boot up the game with the newest coolest graphics and run it at 1080p on my 4K monitor, will it look the same as it would have on a native 1080p screen? The 4K (3840x2160) is exactly 1080p * 2, so there should just be...

Re: How do you actually run games on high-spec monitors?

Certainly, having a ton of graphics power beats not having a ton of graphics power. Discussions like this just inevitably contain a lot of statements like "4K is pointless without a 1080 Ti", at which point I've got to wonder what's being smoked. Indeed. It's nice, but not a requirement. :)

Re: How do you actually run games on high-spec monitors?

If you wanna game at all, you wanna game with da fruits. The quality levels dialled up all nice and high. Otherwise why bother? Sorry, your GTX780 is decidedly low-spec for modern games. I guess we can agree to disagree here. Some of my favorite games are quite ugly in terms of graphics quality. Th...

Re: Kampman wants 32 Core benchies? Here are a few!

I'm not even sure why we should care about this % of peak number at all. Paying for dark silicon isn't a good thing. I care because the primary purpose of the HPC clusters I help design and run is to run problems very similar to HPCG in terms of workload. Going from 1.5% to 3% means the system cost...

Re: How do you actually run games on high-spec monitors?

I realise I don't have the absolute fastest GPU out there but even so it's still comfortably in the top-end of modern hardware, and yet it seems like running much more than a bog standard 1080p monitor is unlikely to perform well. Ahh, no. And that's your problem. Your GTX1060 is most decidedly ped...

Re: How do you actually run games on high-spec monitors?

The ability to maintain high settings is not a pointless endeavour. Sacrificing high settings to gain 4K is. I didn't say it was pointless, I said the drive to run everything maxed out is. "High" is relative. If you can run a game at medium settings and it still looks good to you , who ca...

Turn settings down and breathe easy. Honestly, the obsession with "MAX ULTRA KILLAH SETTINGS" is somewhat pointless and a great way to spend a lot of money. :)

In short: Power9 + Volta is something like 4x stronger in HPCG's memory-intensive test than the next non-Power9 / Volta system. ...and it's 1.5% efficient at doing that. 1.5%. Repeat that a few times. That means a similar exascale machine (in FLOP count) would only run 15 PF on that test... You're ...

The problem is one of logical organization of cores. 2-0-2-0 implies that cores 0-7 (or 1-8 if you prefer) will have access to a full 2 channels of memory bandwidth without the need to jump over infinity fabric to send/receive data in memory, and the next set of 8 cores will have to make that hop o...

I hate mdraid with a passion (mostly because of issue #5 you noted, rebooting is simply NOT an option sometimes). If you're going software RAID and you don't need a particular FS over it...use ZFS.

Another vote for tanker27's suggestion. Mod Mics are great, but pricey. Gaming headsets are almost universally trash if you care at all about faithful sound reproduction.
