Re: Best use of an AMD Opteron 6128 HE

Hi ca05065
maybe you should set the wifi regional parameter correctly; e.g.
sudo iw reg set XX

where XX is the corresponding country code.

On my side, I do not experience any specific Linux wifi trouble with laptops.
Cheers,
Yves

I use Linux Mint and used to have trouble with my wi-fi, but the trouble was not with the operating system, but with my range extender. It was sketchy at best. I upgraded from G to N about 3 years ago and the wi-fi has been spot on since. I could upgrade to AC but if I am currently have zero problems, I am not going to mess with it. I would look at the wi-fi hardware before I look at the operating system.

Re: Best use of an AMD Opteron 6128 HE

I too have the same issue with my Linux machines running mint.Usually they run for months at an end without an issue.
But if i have to reboot my router or something, then they won't always automatically reconnect

Re: Best use of an AMD Opteron 6128 HE

Regarding wifi I haven't had any issues with the one laptop I have running it (i7-3610QM).

One problem I do have with it is that turbo boost is not utilized under Linux and I'm not sure why. It is enabled in the bios and it runs beautifully under windows.

I don't want to dual boot for fear of having to mess with grub or any of that stuff - but I feel like I'm losing quite a few points by not being able to utilize the turbo boost. Then again, on that same note, I'm not producing as much heat and the CPU fan doesn't stay wound up all the way. I just ended a project on its GPU as that fan I think is starting to fail, but it doesn't seem to be used in general processor intensive tasks.

thanks for that sensors utility. It's handy.

Re: Best use of an AMD Opteron 6128 HE

I think you are better off without the turbo boost running. I am not sure what you would gain from the boost, but maybe 5-10%. Correct me if I am wrong. You stated the fan does not run nearly as much, so you are probably extending the not only the life of the fan, but also the life of your machine. Heat in a laptop can be highly detrimental. That is one reason I don't crunch on any laptops. I don't think they are built to run 24/7 at 100%. But I will agree they are a lot stingier on electrical use.
Just for what it is worth. I have installed a laptop with dual boot Linux and Windows Vista, quite a while back. The procedure was painless. When I installed Linux, it asked during installation if I wanted dual boot, I answered yes and I think the installer took care of allocating space for the Linux partition. A screen comes up during the boot process which asks which operating system I wish to run and I just select the one I want.
Cheers

Re: Best use of an AMD Opteron 6128 HE

That was my thought exactly.
I mainly crunch on a few laptops because I don't have a lot of space for large (ish) desktop towers. It is also very rare that I actually get the chance to have a newer desktop machine. I'm not sure how detrimental it would be to run it at 60-65 C for prolonged periods over a period of years, since I plan to keep this machine for at least 4 or 5. The laptop in question has been crunching for around 2 years off and on if memory serves.

I suppose I could run it with the power profile set to power saving when I'm not home. I believe the processor doesn't utilize turbo core this way.

Edit: Just went and looked at the stats. Since switching the Linux machines to the suggested projects points per day for them have very nearly doubled. Not that I'm looking at collecting points, but it's a nice feeling to seemingly contribute more to specific projects with older hardware running linux than newer ones can with windows. I wonder how much of a pain it would be to run linux on this ryzen from a thumb drive. Curious what kind of points I'd receive - doubtless a lot.

Re: Best use of an AMD Opteron 6128 HE

My one Linux box, a Dell small form factor OptiPlex 380 with a CPU from 2010 or so (see signature), runs barebones Debian (using their net install ISO) from a 16 GB USB flash drive. It's been over a year since I set it up. It's set it-and-forget-it except for summer where it overheats. The Autodock Vina work units (like Zika, Ebola, etc.) are as fast or faster than an 8th Generation CPU (Coffee Lake) on Windows!

A Ryzen (8 core?) would write more to a flash drive, but they're cheap enough that if/when the flash drive fails, it'll have been worth it. Pop in a new one and keep calm and crunch on. :)

How about an old but bullet proof MLC SSD like a Samsung 830?

I have a couple of 24 thread servers running on 16gb Sandisk flashdrives and they seem to run just fine. If BOINC is the only thing running on them, it is no big deal if the flashdrive fails, just put another in. Any work unit on the flashdrive will just get re-issued to another machine. Running 8 cores should be no problem.
Cheers
