After you told your boss about the GPU problem I gave you for homework, they asked you
Question:
After you told your boss about the GPU problem I gave you for homework, they asked you to design a server blade that has 6 GPUs. They want these blades to be as powerful as possible. They heard that the company Nvidia sells GPUs for this purpose. They are the Titan series of GPUs. The GPU's they are interested in and the associated costs are:
Titan RTX $2,500Titan V CEO Edition $5,000Titan V $3,000Titan Xp $1,650Titan X Pascal $1,250
Based upon the information on TechPowerUp's web site:
Q1 (2 pts) What is the GPU to use if you need to maximize FP32 (Float) performance?
GPU to use:
Q2 (6pts) How much does it cost for 6 of those? How much FP32 and FP64 performance do you get from 6 of those GPUs combined?
Total Cost:
Total FP32 performance:
Total FP64 performance:
Q3 (2pts) What is the GPU you would use if you need to maximize FP64 (Double) performance? (Make sure to check your units!)
GPU to use:
Q4 (6pts) How much does it cost for 6 of those from Q4? How much FP32 and FP64 performance do you get from 6 of those GPUs combined?
Total Cost:
Total FP32 performance:
Total FP64 performance:
Q5 (10pts) Between the 2 sets of GPUs, those from Q1 and Q3:
What is the difference in FP32 performance?
What is the difference in FP64 performance?
What is the difference in cost?
If you will do most (80%) of your calculations using FP32 and 20% doing FP64, which set of GPUs would you choose and why?
Suppose that you heard about the GPGPUs another company makes. These GPGPUs tend to be cheaper and more powerful. They come from AMD and the model numbers and costs are:
AMD FirePro S9150 $300, Radeon Instinct MI25 $ 4,200Radeon Instinct MI50 $ $8,000
The specs for the S9150 is available here. https://www.techpowerup.com/gpu-specs/firepro-s9150.c2608
Q6 (8 pts) What GPU will you select? What are the total costs, total FP32 and FP64 calculations?
GPU to use:
Total Cost:
Total FP32 performance:
Total FP64 performance:
Q7 (4pts) Between the set of GPUs you suggested in Q5 and the GPU you select from Q6, which set would you choose and why?
All the GPGPUs above were really expensive, for the most part. None of them let you watch things on a screen. Consumer level GPUs can give you the ability to play video games and compute when not in use. Some of the best GPUs out right now for both computing and video gaming and cost are:
RTX 2080ti $1,100RTX 2080 $800GTX 1660 ti $ 270
Radeon RX5700 $ 400Radeon VII $700Vega 64 $400
Q8 (12 pts)
Which GPU gives the best FP32?
Which GPU gives the best FP64?
Among the 6 gpus above, which one would you use and why? (Remember, you need to watch videos and compute.)
For the price, what is a better option, buying consumer grade GPUs or the best set of GPGPUs from earlier?
