Building CUDA-aware openMPI on Ubuntu 12.04 cannot find cuda.h -

-

i building openmpi 1.8.5 on ubuntu 12.04 cuda 6.5 installed , tested default samples. intend run on single node following configuration:

dell precision t7400
dual xeon x5450
nvidia gt730/tesla c1060

the configure command issued was

    $ ./configure --prefix=/usr --with-cuda=/usr/local/cuda

in generated config.log, clear the configure script not able find cuda.h , cuda_runtime_api.h in /usr/loca/cuda/include, exist.

for cuda.h:

    configure:73774: checking cuda.h usability     configure:73774: gcc -std=gnu99 -c -o3 -dndebug    conftest.c >&5     conftest.c:645:18: fatal error: cuda.h: no such file or directory     compilation terminated.     configure:73774: $? = 1     configure: failed program was:     | /* confdefs.h */

for cuda_runtime_api.h:

    configure:73857: checking cuda_runtime_api.h presence     configure:73857: gcc -e   conftest.c     conftest.c:612:30: fatal error: cuda_runtime_api.h: no such file or directory     compilation terminated.     configure:73857: $? = 1     configure: failed program was:     | /* confdefs.h */

i tried change path version-specific directory, i.e. /usr/loca/cuda-6.5/cuda same error thrown.

i tried proceed install, , ompi_info gave 

    mca:mpi:base:param:mpi_built_with_cuda_support:value:false

does had similar experience can me out? many thanks!

ok, think fixed problem. conftest.c seems looking cuda.h in /usr/include, instead of supposed /usr/local/cuda/include. problem solved once created soft link of cuda.h , cuda_runtime_api.h.

i have following code almost works properly; private void cbstatus_drawitem(object sender, listboxdrawitemeventargs e) { string item = e.item string; if (item != null) { switch (item) { case "1": e.appearance.forecolor = color.green; e.appearance.backcolor = color.green; break; case "2": e.appearance.forecolor = color.orange; e.appearance.backcolor = color.orange; break; case "3": e.appearance.forecolor = color.red; e.appearance.backcolor = color.red; break; } } } when dropdown shown, items forecolor correct, backcolor remains whatever backcolor of theme is; i.e. if i've got set dark theme, backcolor dark, cells in gridview, rather being green/orange/red. i've tried setting e.appearance.options.usebackcolor trying set e....
