You can easily run a workload with 20tb/day on a single thread ripper. My last contract we wrote a c tool that did dsp on 10tb/day data with a latency of 50 mi

My last contract we wrote a c tool that did dsp on 10tb/day data with a latency of 50 microseconds. We are using less than 10% of the CPU on that.
- fxtentacle 7y agoYeah, the ThreadRippers are amazing. I was truly astonished when I noticed that one hour of V-Ray on 3970X outperformed $1000 in ChaosCloud rendering. At a price of $2500 once for the TR versus $24,000 per day for cloud, it's a no-brainer to buy them. Sadly, availability in my area is pretty spotty and even Amazon currently predicts 2+ weeks of delivery time.
- threeseed 7y agoNot sure where you are getting your costs from. Threadripper 3970x = 32 cores @ $1999 AWS c5.9xlarge = 36 vCPUs @ $8.34/day (spot) You could buy a year of AWS for the same price as a Threadripper based PC.
- fxtentacle 7y agoI was comparing with ChaosCloud: https://www.chaosgroup.com/cloud https://www.chaosgroup.com/cloud For EC2, one would need to rent licenses for the V-Ray renderer plus V-Ray tends to be heavily CPU-cache- and memory-bound, so exactly the parts that get slow if you enable the Intel security fixes. Due to c5.9xlarge being Xeons, they are like 80% slower than a comparable AMD CPU. BTW, calculator.s3.amazonaws.com quotes me $1119 per month for a single c5.9xlarge, so I'm not sure how you would reach $8/day when I see $37/day.
- threeseed 7y agoThen switch to the AMD based c5a.9xlarge which is even cheaper. And you can reach $8/day using Spot or Reserved Instances. Not sure where you get $1119.
- muzakthings 7y agowhat kind of DSP were you doing? can I come work for you haha
