hello!
i have a problem with data transfer from host to device. i need to pass really big database from host to device and do some calculations. but i just could pass 18.6 Mbytes, i want to learn what restricts this and how i can pass more datas in one time?
and here some properties of my nvidia. at first i thought i could use all of this 911605760 bytes, is it a wrong idea :)? (btw another thing maybe restrict me because i use shared memory?)
Device 0: “GeForce GTX 275”
CUDA Driver Version: 3.20
CUDA Runtime Version: 3.20
CUDA Capability Major/Minor version number: 1.3
Total amount of global memory: 911605760 bytes
Multiprocessors x Cores/MP = Cores: 30 (MP) x 8 (Cores/MP) = 240 (Cores)
Total amount of constant memory: 65536 bytes
Total amount of shared memory per block: 16384 bytes
Total number of registers available per block: 16384
and last thing when i try to transfer more than 18.6 mbytes, the graphics card stop working for 2 seconds and work again.
