Re: CHIA and PrimoCache

Jaga - I appreaciate your suggestions - thank you. I do not use mechanical disks - only SSD for plotting. My plots are stored on a separate NAS. So perhaps with that in light that changes your recommendation? But to be honest I am already considering changing my setup. I will be selling my SSDs and ...

Re: CHIA and PrimoCache

I have tried this MadMax plotter and I am damn impressed. But it is not zero writes to the disk. It says 25%. Still it is in the league of its own compared to the vanila plotter. I also tried to use PrimoCache instead of RAM drive and got some amazing results! SoftPerfect Ramdisk / 116000MB / Plot t...

Making deferred writes more sequential

For deferred writes with infinite timeout. Based on my observations am I right in guessing that cache flushing is done on first-in-first-out basis? If so I would propose to introduce a system to periodically re-order cached blocks (or block index) based on block LBA number. This should result in hig...

Re: CHIA and PrimoCache

Nice one. I own PrimoCache already and have been experimenting with all possible settings combinations. Your good trimmed blocks and cached reads come from the fact that large size of the plot file effectively sits in your L1 cache. Have L1 cache large enough to fit it completely and you won't be se...

Re: CHIA and PrimoCache

Just wanted to pitch in as I have been plotting for over a month, created 114TiB plots so far. Currently getting 1 plot out in just under an hour. Rig is 16-core AMD CPU, 2TB nvme SSD, 64GB RAM, Windows10. I found that once plots are optimally staggered then it is down to raw temp drive bandwidth. A...

Re: CHIA and PrimoCache

Would it be possible to add feature to block disk reads during cache flush? I only just started with Chia. I am exploring PrimoCache (vs Windows large cache setting) to speed up plotting too so very interested in this development. Deferred writes speed up the process a bit (better than windows nativ...
