Topic 228906

Need ideas regarding crunching mix of Einstein and Milky Way.  I do not have an unlimited supply of PCs so I try to carefully select utilization.  This involves two of my PCs:  Dell XPS8930, Intel i7-8700k CPU with 12 core, one running at 3.7 GHz, one at 3.2 GHz. Both machines have NVIDIA installed.  Situation:  Milky does NOT have work for the Intel GPU at this time and Einstein does. I dislike leaving processing power unused so I left both hosts with Milky primary and added Einstein Gamma-ray  pulse search #1 on GPU's 1.22 FGRP open cl-intel-gpu problems so that I can keep the intelGPUs busy.  Both of them are now processing the Einstein  intelGPU projects in 1:41:45 (+/-) one second.  I am not sure what processing priority I should give to Ein or MW.  Am I barking up the wrong tree?  Is there a better way to utilize intelGPUs?  Note:  I do not write code or insert it, so I am left with making processing selections on both web sites.  BOTTOM LINE objective is to process the maximum amount of work for both of these sites.  These are the only two sites I am crunching for at this time.  Any ideas/solutions/corrections appreciated.  Thanks folks!

I believe that the general consensus is that if you are using a discrete gpu in the host that disabling the igpu is the smartest thing to do so it doesn't slow down the cpu and gpu applications.

I am running Einstein@home on

I am running Einstein@home on a Microsoft Surface laptop with other 5 projects under Science United. since I am back from a hospital stay and did not remember all my passwords. It has an integrated Intel GPU processor and no discrete board. GPU-Z gives the GPU clock at 748 MHz .The CPU has 6 cores and 12 threads,

Tullio, I am sorry to hear

Tullio,

I am sorry to hear you are back in the hospital!

James,

I am one of the people who tested running with and without Intel iGpu's. There are almost certainly exceptions but most people get more discrete GPU and CPU if they are not processing on their Intel iGpu's.

If you are running laptops I would put them on "cool tables" to help lower their system temperatures.

Many laptops do not seem to survive a 24/7 processing situation unless they are running Very cool.

Yes, that's true. But with the help of some hardware diagnosis tools one can readout power consumption of the iGPU core within the CPU. Disabling the iGPU core reduces power consumption and heat. When running BOINC with some tools limiting CPU temperature (e.g. limiting fan noise and overall heat output of small sized desktop PCs, Notebooks etc.) then disabling the iGPU will speedup CPU crunching (balancing power consumption and heat production in favour of CPU cores instead of iGPU core).

It's on the same silicon and the CPU heatsink spreads the heat. So, temperatures of the cores cannot differ greatly.

I  need the iGPU to run Einstein.I could not run GPUgrid since it needs CUDA.

I am no longer in the hospital but in a Residence home for old people. I am almost 88.

WOO HOO out of the hospital is a good thing!!

Einstein does have cpu tasks as well, I'm doing the O3 cpu tasks but they do take almost 2gb of ram for each tasks.

Incredible. My utmost respect. Handling details of Boinc projects and CPU specifics. I've never heard of anyone of your generation being a geek. My father is 20 years younger and only knows web browsers and MS Word. I'm totally blown away. I wish you a long and healthy life and that your curiosity for new things never dries up.

[EDIT]: My astonishment was based on the lack of knowledge of your impressive academic career. (I should read backgrounds first)

a am now running

a am now running Einstein@home, physics,SiDock@home, biology,Numberfield, mathematics. I use to cooperate with CERN, which has jectme a letter of thanks because I helped them, in atarting a project using VirtualBox, Testing4Theory@home which has now a different name, The letter was signed by Ben Segal, a member of the internet Council. I have I also a letter by Roger Penrose in 1995, before he was made Nobel Prize.
