Verbose info log reporting with cuModuleLoadDataEx does not work reliably on Ubuntu 12.04.2, CUDA driver 319.21, Linux 3.5.0-36 on x86_64. The problem does not appear to be GPU specific. The machine has a Tesla C2075 and a GeForce GTX560.
C source that demonstrate the problem: [url]https://gist.github.com/sklam/6091525[/url]
The program works as expected on OSX 10.8 cuda driver version 5.5.12. It should print:
device inited
context inited
load module
ptxas info : 0 bytes gmem
ptxas info : Compiling entry function ‘sum’ for ‘sm_30’
ptxas info : Function properties for sum
0 bytes stack frame, 0 bytes spill stores, 0 bytes spill loads
ptxas info : Used 6 registers, 328 bytes cmem[0]
cleanup
end
