December Projects of the Month

[email protected]

Start: 22 - Goal: 21 - End: 22 |  It has been more than three years since we had LHC as a POTM.

 

SRBase

Start: 36 - Goal: 30 - End: 26 |  It is a bit of feast or famine for tasks, but if the queues are kept full we can probably move up a number of spots. :thumb:

Start: 22 - Goal: 21 - End: 22 |  Will be a heck of a month if we can move up to 21, but we can give it a go. :D

 

 

A bit of a different mix for the last month of the year. :)

I'll switch over to SRBase. Still got some badges to grind. thumb.gif

I have been having issues with Einstein.  Not sure what the deal is, but I am getting driver crashes on my 290s and my 1070s.  No issues on my 480 which is running the same OS and drivers as my 290s and 1070s. :headscrat

 

After killing the stuck tasks, they go into uninterruptable sleep and I have to shutdown and reboot in order to clear the stuck tasks.  I haven't had time to see what is going on, but hopefully I can get it sorted out over the weekend.

Looks like my Ryzen 1800X has terrible performance compared to my slower intel 2670 v0 processors when crunching SRBase. thinking.gif

I scanned through the top computers and the first Ryzen that appears is at #190 place...

There is really no way that a 2670 should be 20% faster than an 1800X.  The only thing I could find was a post from April where rebirther said that it is not optimized for Ryzen yet.

 

I just loaded it up in Linux to see if it is a Windows issue, or if Ryzen is just knee-capped on this project

*Edit* I show the same results in Linux.  My R7 1700 is about 30% slower than my 2670v2

 

You might try and start a thread in the forums, since rebirther is active and is obviously optimizing the project with the use of AVX, AVX2, and FMA3.

LHC seems to be mostly ATLAS units (i.e. using VirtualBox) right now.

All I've gotten the past few weeks have been Atlas. There was a post about it somewhere on their forums. Got 4 threads of 1950x (ends up utilizing about 2.5-3) and about 1 threads worth of a 3570k. 9.8gb of memory usage on the 1950x and 5.3gb on 3570k.

Finished my Moo tasks and moved over the RX 580 to [email protected]

Just fired up six 4-core Atlas tasks on my 2P.  Running six 4-core tasks uses roughly 35GB of memory on my 2P.  I did have to use an app_config with a much higher memory allocation than anything I saw on the forums, in order for the tasks to truly use 4 cores per task. 

 

Maybe they just take a while to start and I could have left the memory set at a lower value, but for the first thirty minutes each of the six tasks I was running were only using a single thread.  Once I upped the memory to 40GB in the app_config, the tasks immediately started using 4 threads each.

They either take awhile to get up to higher CPU usage or it takes awhile to write nearly 10gb of data. They go from less than 1 core of CPU time to something like 2.5 cores for me when set to 4. I run a couple of CPU tasks on my 2nd client for GPUs to keep the CPU busy at all times.

Was browsing LHC forums and found a thread about this topic. Looks like 4, 5 and 3 threads are the most efficient.
