Prime95 v30.3

The main Memory= setting in local.txt controls the overall amount of RAM Prime95 can use for stage2 workers. If nothing else is specified, it's a first-come-first-served pool: first worker takes as much RAM as it wants, second worker takes the lesser of what it wants or what's available, etc. When the first worker is done with stage2 that RAM is released to the pool, and some/all stage2 workers might restart if they're currently using less RAM than they wanted to. When the amount of RAM for stage2 is small (e.g. P-1 in the 10M range) it's not a huge deal, but on wavefront P-1 on older machines (like mine) it can take 10 mins or more to re-initialize stage2, so stage2-thrashing should be avoided. In my case I'm allocating 40GB for stage2, but manually specifying that each of two workers can have up to 20GB, by putting another Memory= line under each Worker #x section.

Thanks for the note on individual worker memory, James.

That is correct. And GPU72 does absolutely no caching of [FC | DC] candidates. All requests are simply passed onto Primenet for all assignments except P-1. (Read: each proxied machine receives the usual Primenet assignment rules filtered work.)

There was a new field added for the Cert work which breaks the comms. WAY too busy to fix ATM. I wouldn't mind deprecating the GPU72 Proxy, actually.

I'll second that!
Most of my systems did not have a worker section in local.txt.
It might look something like

[Worker #1]
Memory=32768

[Worker #2]
Memory=32768 during 7:30-23:30 else 32768

I have found that running mprime with Ubuntu on Windows results in sometimes unexpected behavior, such as results files being deleted after results are submitted or having attributes which makes them invisible. After tracking down the folders' full path, I pinned the location in Windows File Manager. This is most likely the source of the issues. Having its own GUI file manager would help greatly. I do not think such an animal exists. I find mprime preferable to Prime95. I have my reasons, long discussed and lambasted over.

You can navigate to the Windows filesystem.

Here is an example from our machine:

m@i9-10900KF:~$ pwd
 /home/m

m@i9-10900KF:~$ cd /mnt/c/Users/m/Desktop/
 
m@i9-10900KF:/mnt/c/Users/m/Desktop$ ls -l
total 44
-rwxrwxrwx 1 m m  6214 Oct  3 13:16 250w.txt
-rwxrwxrwx 1 m m  6209 Oct  3 13:16 25w.txt
drwxrwxrwx 1 m m  4096 Oct  3 12:41 benchmark
-rwxrwxrwx 1 m m   282 Sep 24 08:32 desktop.ini
-rwxrwxrwx 1 m m 27136 Oct  2 21:51 i9.png
drwxrwxrwx 1 m m  4096 Oct  3 13:20 mfaktc
drwxrwxrwx 1 m m  4096 Oct  3 13:17 prime95

You can then use the Windows file manager for your Linux files.

There is another solution. A dual-boot system using the existing Windows 10 setup and Ubuntu 20.04 LTS. My SSD is 250GB. Windows 10 is using about 65 GB of that space. I found a walk-thru article on the web. I shrunk the Windows volume by 70 GB. This should be enough. It says to leave the shrink space unallocated. I have the ISO I download from the Ubuntu web site. All I need to do now is to burn the ISO onto a DVD. The Ubuntu installation prompts are different than they would be on a totally empty drive, according to the article. My HP Windows 7 system is about six feet away. I can load the article there and follow it as I go along.

If you were going to dual boot just for the sake of running mprime or the like, you could boot off a usb drive.

This is very true. At most, it would be mprime, mfaktc, and gpuowl. I am not sure how I would pick which drive, unless one of the other presented a menu to choose from. Having to reconfigure the BIOS ever time I wanted to switch is not something I would like to to.

To be honest, I am not crazy about messing with the SSD. I have an extra 500 GB spinner in a box. I am leaning toward using it.

Last I checked a 64gb USB drive was about $18 at rite-aid, so you could use the usb drive not only to hold the OS and the programs but the result, too. And just plug it into the windows OS to upload it.

What file system do you use to run linux that is readable by Windows in that scenario?
