Ubuntu 18.04.1 LTS and AMD Radeon RX580

[davidbam]

not much to say ... it all worked like a dream with iso from https://www.ubuntu.com/download/desktop

4K screen even during installation and Boinc saw the GPU right away

Nice job guys

I am crunching Collatz at the moment as there doesn't seem to be much choice for AMD GPU. Any suggestions please?

Seriously ??? You have a AMD crunching on Linux without having major hair loss !! That in it self is a major achievement. I think I will have to try and see if my 7970's now work easily. Collatz is the daddy for points, if you have decent double precision on that GPU then Milkyway@home is also worth a look. Enigma is good to if you fancy some historical code breaking.

Why did you have to mention hair loss !!! At least it wasn't caused by this setup

HD7970 has no VEGA chips, so no go. Only VEGA architecture is supported under Linux, crunching-wise, sorry.

Has anyone tried the Radeon RX Vega 64 - it is a bit greedy at 295W (the RX580 is 185W). Is it worth the extra purchase and running costs ?

Also now crunching under Ubuntu 18.04.1 LTS on a Firepro W5100 https://www.amd.com/en/products/profess ... epro-w5100

Collatz reports it as

AMD BONAIRE (DRM 2.50.0 / 4.15.0-36-generic, LLVM 6.0.0) (4096MB) OpenCL: 1.1

Out of interest, I fitted two graphics cards into the same machine (ubuntu with rx580 and a Firepro W5100)

xrandr correctly reports both cards but Boinc doesn't give any work to the second card (even when I leave a CPU core spare).

Not a deal-breaker but I'd be interested if anyone has got multiple cards working under Linux before? Either 2 x AMD, 2 x nVidia or one of each

Sorted. In cc_config.xml

Code: Select all

<options>
        <use_all_gpus>1</use_all_gpus>
</options>

Beat me to it. I had 4 x nVidias crunching in Caro with a workstation server board. 1200W PSU required for that set up.
