cuda - Reading mxArray in CUSP or in cuSPARSE -


i trying read mxarray matlab custom made .cu file. have 2 sparse matrices operate on. how read them inside cusp sparse matrices , b ( or in cusparse matrices), can perform operations , return them matlab. 1 idea come write mxarrays in .mtx file , read it. again, there alternatives?

further, trying understand various cusp mechanisms using examples posted on website.but every try compile , run examples, getting following error.

terminate called after throwing instance of 'thrust::system::detail::bad_alloc'   what():  n6thrust6system6detail9bad_alloce: cuda driver version insufficient cuda runtime version abort

here stuff installed on machine using.

cuda   v4.2 thrust v1.6 cusp   v0.3

i using gtx 480 linux x86_64 on machine. strangely enough, code device query returning output.

cuda device query... there 0 cuda devices.  press key exit...

i updated drivers , sdk few days. not sure whats wrong.

i know, asking lot in 1 questions facing problem quite while , upgrading , downgrading drivers doesn't seem solve.

cheers

this error revealing, "cuda driver version insufficient cuda runtime version". need update driver.

i use cusparse/cusp through jacket's sparse linear algebra library. it's been good, wish there more sparse features available in cusparse/cusp. hear jacket going cula sparse soon, that'll nice.
