Hello There is a minum quantity of ram for using mad max plotter?
I wanted just to make some test but this point is still not clear for me.
Reading something it says to use ramdisk but I dont understand how minimum is necessary to do that.
Thank you for your help.
So it is not necessary to use ram disk but if you use it you can improve the time for plotting.
is it correct?
Just to know with no ram disk how much is faster than usual plotter ?
Are there any Speed-Compairs between different bucketcounts for madmax?
For my tiny plotter it SEEMS that there is not mutch difference between -r 4 -u 128 and -u 64…
Maybee using a high -u and additional cache could be a consideration?
I am using 5950x, 128gb ram, ramdisk of 110gb and plotting with no issue.
I am using Imdisk to create ramdisk on win10. I used dynamic ramdisk so I see the memory allocation go up and down as needed.
Mind you I am also running other vms on this same box so there is some paging but it is a much better experience than I was parallel plotting on multiple nvme drives.
Dear all, I have got an Threadripper 2950X ,ALSO 16-Core*, 32-Thread By madmax in Windows 10 version, even with 128 G memory disk as temp 2 drive, I could only make the time from 50-55 minutes, which is quite depressing from what I saw here…
Any idea how to improve this Gen 2 which should be quite be powerful CPU back to those days~~~~
2950X 16-Core*, 32-Thread
Temp1 :2G NVME (Gen3 2000+MB/s read&write)
Temp2:118G ramdisk in windows (which tested with 7000+MB/s read&write, not as fast as I though, but still quite fast than Gen3 NVME)
32
128
time:3000 s +
Hope get some advise here ,thanks guys~~
try a high bucket count (512)… this reduces the memory needed per thread and you’ll be able to use all 32 threads with the ram disk (110GB + 32 thread *0.25 + 10GB for OS)
one thing to mention, Linux has the ram disk ‘built in’ while Windows you use a 3rd party tool and I’ve seen reports Windows underperforms by up to 50%
you can also try 256 buckets = 0.5GB per thread, but I don’t think that leaves enough RAM for the OS… you may be ok on a headless Ubuntu with 2GB
much appreciated for your advise, sure, I will try Linux this weekend, for this 2950X machine,I will try to use it as a learning platform for Studying Linux since actually I have almost complete my plotting.
Now I am more interested in this new technology and want to learn more new things.
I’m able to plot using madmax with a ramdisk on Windows 10 and 128gb of ram. I thought this would cause problems but so far everything is running smoothly. In madmax readme it says the ramdrive should be 110gib which is 118gb (maybe a typo) but it seems to work fine with an imdisk partition of 112gb. Am I missing something?
