Stress testing a server with 8X E7-2860's

[Jeff7181]

Long story short... got new servers at work with eight E7-2860's... that's 80 cores (hyperthreading disabled).

I'm trying to find a way to stress test them without actually putting a production load on them. Prime95 x64 isn't cutting it. It only wants to run 20 threads at a time and I'm having trouble getting it to use all 80 cores even if I do run multiple instances and set the affinity.

Any other simple stress testing apps that would be able to push all 80 cores to 100% and use a large portion of the 384 GB of memory in the servers?

Why do you have to stress test them? Only an overclocker would consider that.

 

[soccerballtux]

shouldn't need to stress them? You buy such a system with the guarantee that it's going to work?

Nah, it's still a good idea to stress-test servers, before putting an actual load on them.

OP, have you tried F@H?

If you have a VM image, you could run dozens of duplicates

boinc primegrid,
any llr test

Don't really want to install any agents or any BOINC stuff. I'd prefer a standalone executable like Prime95.

I'm stress testing because these are the first of these model servers that we bought, and one arrived damaged. Yes, they should be able to handle a big load (hahaha) but I'd prefer to do a little "burn in" to see how they handle it to see if I need to add another vented floor tile in front of the rack or possibly not put all 4 in the same rack.

Finding out one of these is in a hot spot or something after they're put into production simply isn't an option.

You can start four instances of Prime95 using the switch -A0 to -A3 on the executable. Once you have all 4 going with 20 threads, go into Windows task manager and set the affinity for the cores you want each instance to run on.

Edit: Sorry, I read your whole post and see that you've already tried this.

Figured it out... cranking away now...

Wowzers...

Run FAH on it now1!!!1!!

or bitcoin mining, though he'd probably only get 80-100MH or so

 

[Jeff7181]

Haha. I wish. I only have until the end of the week with them until I turn them over to our database admins.

Could you run handbrake and see how well it does video encoding?

 

[Jeff7181]

Unfortunately, no. Would be cool though... transcode a movie in 10 minutes.
