Hi all, in a general sense. I have 8 cores 16 threads system. (Technically ) able to parallel plot 8 plots with 32gb ram. However, my system is 64gb ram if instead of 4000 ram 2 threads. If i increase the ram to 6750 2 threads, will i result in faster plotting times?
No. You’re going to be IO limited more than RAM. Or CPU limited depending on how old your CPU is. But most likely IO limited.
Not faster but in some circumstances will allow you to run more plots in parallel
my situation is i7 10700F 8 cores 16 threads with 64gb 3200dram 2x2tb m.2 nvme with a 512sata ssd (OS) with a few 16tb external hdd.
i am currently still figuring out what is the optimal plot settings for my scenario.
4000 ram 2 threads (8plots) parallel?
6750ram 4threads (4 plots) parallel?
technically from what i read and the response, my 8 cores can only do 8 parallel.
Yes, I observed, but not measured slight increase of speed when I went from 3 GB to 5 GB per job.
Yeah adding memory is one of the worst things to do, it has basically negligible effect on plot times. Adding threads on the other hand, going to 4 is like 10-15% faster, and 6 is maybe 2% faster.
Exactly. My main plotting machine has 64GB of RAM and I can’t get it to use more than about 30GB of that. Maybe when my new faster SSDs arrive it will
Adding threads…so you could do potentially something like 3 threads for 2 plots where (speaking loosely) each plot is using 1.5 cores?
Possibly! People tend to add threads in batches of 2 for some reason, but I’d be curious to see a test of 3 threads vs 2 vs 4. I did some testing of my own here:
IO was mentioned in one of the recent YT vids, how do we go about checking / calculating IO available before we hit the limit?
Do you think going from an i7-9700K to a 5950x would result in a noticeable difference in plotting time?
I’m using 5950x and my plots are around 15.4k with 4t and 6750 mem.
Dougie, how many rams are u running at. Thinking of upgrading too… 15.4 plots a day? Or at once. How many plots a day
That was 4 plots with 36min stagger I think (32gb) Totally changed now and trying to get it all working on ubuntu but couldn’t even get 1 plot finished in 10 hrs with 1hr stagger. 64gb arriving tomorrow so going to fresh install and try again.
