matlab - gpuDevice command takes looong time to complete -
i testing whether gpu coding works in matlab. found out everytime run gpudevice command after opening matlab first time, takes long time.
tic var = gpudevice() toc >> gpu_test
it takes @ least 100-seconds or more:
var = cudadevice properties: name: 'geforce gtx 1060' index: 1 computecapability: '6.1' supportsdouble: 1 driverversion: 8 toolkitversion: 7.5000 maxthreadsperblock: 1024 maxshmemperblock: 49152 maxthreadblocksize: [1024 1024 64] maxgridsize: [2.1475e+09 65535 65535] simdwidth: 32 totalmemory: 6.4425e+09 availablememory: 5.3035e+09 multiprocessorcount: 10 clockratekhz: 1670500 computemode: 'default' gpuoverlapstransfers: 1 kernelexecutiontimeout: 1 canmaphostmemory: 1 devicesupported: 1 deviceselected: 1 elapsed time 108.818430 seconds.
the thing after first time, same script takes 0.5~1ms run. run-time resets each time start matlab. sort of long runtime expected every time?
thanks, cn
