Hi,

I am currently running 6 machines for Boinc projects and I am trying to work out the processing power (G-L-O-P-S); I have taken a look at the previous questions but they are beyond me.

Could someone help me to calculate an average G-L-O-P-S for this setup? I say average, because I guess you would have to average between processor speed and turbo speed?

Thank you so much for any help on this.

I have included the specs for the CPU/GPU, and the link with the full specifications in-case they are required, where possible.

All machines run either Windows 10 or 7, 64 Bit.

None of the CPUs seem to list GFLOP values? Also I am not sure (if they did) which of the 2 GFLOPS values would be more useful in calculating compute power in Boinc eg Single or Double precision?

Also the GPUs seem to use different metrics for specifications!: Stream processors, CUDA cores, Single and Double GFLOP values, Core speed, Boast speed, Core Clock speed, Memory Clock speed, Shaders, TMU's, etc.

There does not seem to be a constant "specification" usage.

After digging around a bit there is going to be no general calculation. First the single or double precision is going to depend on the project. CPUs do not list GFLOPs because it's comparing apples to oranges. GHz is a measure of operations per second FLOPS is floating point operations per second. While they sound similar there is no way without knowing what calculations are being done to convert GHz to GFLOPS.

*** CORRECT ANSWER ***

Using Intel's data for its microprocessors, and for working out GFLOPs for these, found here:

http://indico.cern.ch/event/403113/contributions/1847268/attachments/1123555/1603259/01_Intel_Architecture_for_HPC_Developers.pdf

This gives us the following formula for calculating GFLOPS for Intel CPUs.

GHz speed x Cores x Operations per cycle (eg Flops per cycle per core)

** see page 20 in Intel PDF above **

Example given by Intel:

Intel Core i7-2710QE (Sandy Bridge)

2.1 GHz x 16 SP FLOPs x 4 #Cores = 134.4 SP GFLOPS.

--

So using the data I originally gave, plus the fact that the Intel HD 4600 GPU is 56 GFLOPS, and the GeoForce 210 is 39.36 GFLOPS, that gives

a Theoretical GFLOPs value for my setup of roughly 2900 GFLOPs (single precision).

Please note this is NOT the actual processing being done on BOINC projects - you can work out (as stated by BOINC) in GFLOPS by:

Recent Average Credit (RAC) / 200.

However with these 2 figures it can give you a better idea of what equipment to buy to reach certain GFLOPs (eg get within Top 100 Volunteers).

Ive heard about these boinc projects before but weren't sure if they were real. I looked on their website and just wanted to know if it was a true business. That is turning your computing power over to medical/physics research and stuff. So I guess it is? What project are you working on?

Hi Jay,

Currently doing data processing for the following academic research projects:

Climate Prediction - Modelling climate change
World Community Grid (IBM etc) - trying to find cures for Aids, Ebola, Cancer, and Zika.
Primegrid - locating primes.
Collatz conjecture - Mathematics.
Einstein - Finding Pulsars.
GPUGrid - Various Medical stuff.
SETI - Analyzing radio signals for intelligent life.
Rosetta - Protein Folding.
Asteroids - Tracking Asteroids and their spin's.

Since this post, I am now running:

2x dual ES620 Xeon workstations (8 cores/16 threads @ 2.4 [2.6] GHz each workstation)
3x dual E5-2670 Xeon workstations (16 cores/32 threads @ 2.6 [3.3] GHz each workstation)
2x i7 4790 Machines (4 cores/8 threads @ 3.6 [4.0] GHz each machine)
GPU Rack with 3x GTX 970 + 1x GTX 750Ti

[Turbo Speed or Overclocked Speed]

chriscambridge,
those are nice builds you have underway. Post some update pictures, if you dont mind. Im considering another Boinc build but not yet sure on the specs. Currently, im running 3 units.
-Xeon2670x2 workstation on 780ti & HD7970
-i7 950 on 780 & R9 270x
-intel ComputeStick (MTBF testing)
anyways, crunch well and looking forward to see your setup. Cheers.

Hi kcharuso,

Our latest builds are now based on the X99 Motherboards (X99 Deluxe) and the E5-2683 V3 Xeons.

X99 can handle multple GPUs at better speeds/gen/slot width, and use DDR4 RAM, and deluxe can auto-overclock. The V3 Xeons have the AVX2 instruction set, and much much lower TDP than the V1s such as the E5-2670s.

I would advise to go with the E5-2683 V3 which you can pick up for around $3/400 each; although the price is rising.

E5-2683 V3 Xeon - 14 Cores / 28 Threads, 2Ghz, Turbo 3 Ghz, all core speed 2.5 Ghz.

If you want to see loads of pictures of our related BOINC build and stuff, take a look at:

Hopefully I can post this link here without any issues.
