I installed CUDA 3.2 RC2 and corresponding Compute SDK. When I run CUDA SDK binaries (bandwidthTest, matrixMul), I obtain messages like
matrixMul.cu(127) : cudaSafeCall() Runtime API error : all CUDA-capable devices are busy or unavailable.
But deviceQuery results looks OK. There is C2050 card installed w/driver 260.19.26 under Open SuSE 11.1.
C2050 is connected w/VGA monitor (integrated VGA controller from Supermicro X8DTI mobo isn’t used), but no X11 is used.
/dev/nvidia* devices were created.
After issuing of ./bandwidthTest, for example, VGA monitor screen content is partially destroyed and contains a continous set of colored lines.
How should I run SDK binaries correctly - or what else may be the source of “busy” state of C2050 ?
Thanks in advance !
