1) Message boards : Number crunching : Crunch on CPU or low-end ATi / Nvidia GPUs? (Message 5442)
Posted 13 Jul 2017 by UBT - Timbo
How do I use it to crunch Asteroids data?


Install the card in your PC
Install the latest NVidia drivers

Start up BOINC Manager - it should detect that a GPU is present.

Go to your Project Preferences, (on your account, on this website) and allow GPU tasks.

Go to BOINC Manager, select the Asteroids project and then click on "update". If you haven't already, set BOINC Manager to "allow new work" on the Asteroids project.

That's about it.

I've had a load of "ps_160915" (sse2) series WU's fail with the code "Abandoned". (44 in total)

There's nothing in the Stderr Out either - not sure what's caused it.

I've also suffered over 80 "Error while computing" the same series tasks.

This time Stderr Out says:

<core_client_version>7.4.23</core_client_version> <![CDATA[ <message> process exited with code 193 (0xc1, -63) </message> <stderr_txt> SIGSEGV: segmentation violation Stack trace (8 frames): ../../projects/asteroidsathome.net_boinc/period_search_10210_x86_64-pc-linux-gnu__sse2(boinc_catch_signal+0x47)[0x422b97] /lib/x86_64-linux-gnu/[0x7fe8824878d0] ../../projects/asteroidsathome.net_boinc/period_search_10210_x86_64-pc-linux-gnu__sse2[0x40ad00] ../../projects/asteroidsathome.net_boinc/period_search_10210_x86_64-pc-linux-gnu__sse2[0x4078c1] ../../projects/asteroidsathome.net_boinc/period_search_10210_x86_64-pc-linux-gnu__sse2[0x407475] ../../projects/asteroidsathome.net_boinc/period_search_10210_x86_64-pc-linux-gnu__sse2[0x40e596] /lib/x86_64-linux-gnu/[0x7fe8820eeb45] ../../projects/asteroidsathome.net_boinc/period_search_10210_x86_64-pc-linux-gnu__sse2[0x4057a1] Exiting... </stderr_txt> ]]>

But, the same PC has generated credits on other "ps_160915" series tasks both before and afterwards without an issue.

Maybe a bad batch ?
