Been a long run. In the early days, it would take almost a week to crunch 1 task with a single core CPU. The last (used) computer I bought has 2 CPUs for 16 cores / 32 threads and can get thru 150 tasks in about a day.

Were the drives purchased? We had $11,600 about 2 months ago for them and a lot of donations after that. So I was hoping to get an update since it's been a couple of months since we reached the fund raising goal.

I'm not seeing the '71' under the S@H V7 column on the server status page. Did those finally get cleaned up in the dbase?

A new case for the Raspberry Pi 4, it has both passive and active cooling, with a script to monitor CPU temps and spin up fan speed when needed.

The Argon 1:

I also like how all ports are on one side & the case has a power/reset button.

Web pages were sluggish, now I have a bunch of stuck downloads with a 3+ hour project backoff for them.

I'm getting the 'Project has not tasks available' message this morning on my 2 windows machines. At least I was able to get restocked last night.

Explaining Computers posted another video about cooling the Raspberry Pi 4, this time with a focus on passive cooling.

For awhile I was crunching numerous low to mid range PCs 24/7. But when the power bill came and was close to $200, I had to back off. I shut down most of them for the remainder of the summer while the AC was running, but now I have my best 2 PCs (or most power hungry PCs) running on opposite schedules (more or less 1 crunching at night and the other during the day) - this way only 1 is crunching at any point in time.

I have noticed that the Windows 10 backup seems to only back up "data" and not the entire system.

What are you using for your weekly backup? I have the external drive just want to do the "best" backup I can.

Tom


I have been using Acronis to capture an image of my C drive or operating system drive on a weekly schedule (full image about once a month, incremental the remainder of the month). This is going to another Windows machine I have a 3 terabyte drive in as a secondary drive. Acronis also sends me an email once that backup is complete so I don't have to remember to check the status of that backup.

I have also used Macrium Reflect numerous times over the years to clone my OS drive when upgrading drives.

I'm also currently testing Backblaze to the cloud. This is a bit expensive but can back up entire drives to the cloud.

For my data only backups I'm using Cloudberry Backup Desktop Edition that backs up data to my Raspberry Pi, Google Drive, a Synology NAS, and an Amazon S3 bucket.

Yesterday I was wondering if all of the the files / loaded tapes were going to get split before we were going to run out of tasks to crunch, but this morning it looks like the servers took a different route and stopped splitting and creating tasks with loaded tapes / files still in the queue.

This file has been on the server status page for months if I'm not mistaken, so I was kinda hoping it would have been split

Hopefully computer stats & tasks look better tomorrow after the dbase servers are a little more sync'd. My machines are not showing any tasks in progress.

. . WTF? One of my rigs just tried to report work and got "down for maintence". Already? But the forums are still up so NOT an actual maintenance outage.



I just noticed the same thing, and communication deferred for 53 minutes

My 3B+ had 2 tasks go into error status since Sunday. I have removed all OC changes I made before and am back to 1.4 GHz. When I made that change, and rebooted the Pi, and I looked at BOINC to make sure tasks etc. were running - and the the remaining (estimated) time for the 4 active tasks were going down between 3 - 6 seconds every second. Kinda strange I thought - but perhaps the Pi runs better at the factory 1.4 GHz setting.

I don't recall if I installed the base desktop Raspbian, or desktop with recommended software / full version.

This doesn't say much if it was the regular desktop or full desktop:

PRETTY_NAME="Raspbian GNU/Linux 9 (stretch)"
NAME="Raspbian GNU/Linux"
VERSION_ID="9"
VERSION="9 (stretch)"
ID=raspbian
ID_LIKE=debian

Kernel is 4.14.79

The changes I made on Sunday:
arm_freq=1500
gpu_freq=500
over_voltage=6

The temps are usually around 48 degrees and still running 4 tasks. The USB fan to the side of it is still at the medium setting which is what it was set at before overclocking the pi.

I've been at 1.45 GHz on my 3B+ for the last 36 hours. No issues with that so just pushed it up to 1.5 just over an hour ago. Still running 4 tasks.

Those are great times for all four cores in use. Good and acceptable temps too. Maybe my concern of overloading the cpu is not valid. Your compute times running 4X are better than mine running 2X.

Can I assume you are running stock clocks at 1.4Ghz? That is what mine run at and I get an error message that my cpu is not overclockable when I choose the overclock selection in raspi-config.


Yes, running my 3B+ at stock clocks. But after watching the below video where it shows how to modify config.txt, I may kick it up to 1.5 Ghz this weekend.

My RPi 3B+ is running 4 tasks and is usually at 45 degrees.

I have a USB fan on the side of it, and it has this heat sink:

My older models run hotter with just 2 tasks running, with a smaller heat sink and other combinations of cases (case with a fan in it, a flirc case case 2 of them).
