    kanikani

      Good day,

      i have two HD 7970 card to perform some science calculation on it using BOINC platform.

      but i have i problem with detection of second GPU.

      BOINC logs next:

      is it driver bug, sdk bug, boinc bug or something else?

      ubuntu 12.10 64bit, catalyst 12.11beta, app sdk 2.7

       

      on ubuntu 12.04 and catalyst 12.10 boinc can't detect second GPU at all:
