Universe & Linux with a VM
« on: January 10, 2021, 11:33:28 AM »

This may or may not be useless information and someone please jump in if my math is way off. I'm not ashamed to say that Math is not my strong point. :thumbdown:

Using my VM and Ubuntu, I crunched 32 tasks and then 16 tasks by setting the CPU usage to 50%. Results were as follows -

Hardware - 3950X
(I used 32 tasks to take an average for both results.)

Running 32T
Average run time was 4,209.34/wu (70.15min/task) There's 1440min in 24hrs so that 20.57 SINGLE tasks in 24 hrs x 32 tasks at a time = 658 task/24hrs?

Running 16T
Average run time was 3,098.44/wu (51.63min/task) There's 1440min in 24hrs so that 27.89 SINGLE tasks in 24 hrs x 16 tasks at a time = 446 task/24hrs?

That's a 67% increase in throughput by using all 32 threads instead of 16 cores.

Please jump in if I got that wrong Bashhead. I give myself 50/50 chance that I got it right.
I should now test between the VM/Ubuntu & Windows 10..... though I'm back to work on Monday so I'm not sure when that will happen. :thumbdown:

You may be doing the tasks quicker but are doing less per day at 50% so it depends on what you are looking for.  I would rather do more tasks for more credit than less tasks for less credit by using all the cores.   I usually have mine set to one core less than the system has.  ie 6 cpus = 100/6=16.66666666666667 * 5 =83.33


Just re read your POST and we are saying the same thing


I usually try and work out how much credit per hour I am going to get to compare against.  run time in secs / 3600 = credit per hour  then  credit for task / credit per hour =

This Numberfields work unit is done on my GPU on Windows

https://numberfields.asu.edu/NumberFields/workunit.php?wuid=98274535

457.58/3600=.1271055555555556    97/.1271055555555556= 763.1452423619913 credits per hour

This is a task on Windows 64 bit CPU

2,830.25/3600=0.7861805555555556     97/0.7861805555555556= 123.3813267379207 credits per hour

I stopped running Numberfields on the machines I had a GPU in and just ran GPU.  I then used the CPU to run another project.

Thanks Dingo.
I think the credits/hr would be easier to work out :)
