no pointcloud is produced when using openCL
« on: February 11, 2014, 08:26:00 PM »
Hello

Photoscan 1.01 fails to produce a pointcloud when using openCL. According to the logfile, it seems as the process does not even start. Can you help ?

I attached two logfiles for the same dataset, with and without enabling openCL.


I am using the following equipment

HP Z800 64G de RAM, bi-proc Xeon E5330 2.4GHz (2x8 cores)
   OS = CentOS 6.5
Graphic card : NVIDIA GTX 690 4G RAM
   driver : NVIDIA-Linux-x86_64-304.119
When enabling Open CL I disactivate two CPUs

PS This is related to my previous question with using openCL but I just realized that the problem is for producing the pointcloud and not the mesh.

Hello Bruno,

Are there any messages in the Console pane when you start Build Dense Cloud stage from GUI? Please also check if any error messages are displayed in the Console pane when you open OpenCL tab in the Preferences window.

In case it is usefull: In relation with this non-functionning of openCL, I cannot stop photoscan with the usual way, I have to kill it externally.

Hello Bruno,

Maybe you can run some OpenCL-test utilities and check if they are reporting any problems?

well,

It seems as we have hardware issues with the graphic card.
Sometimes a hard life to be a newbye...

Thanks for feedbacks,
