I have only recently started experimenting with CUDA and up to 2 weeks ago had successfully created a number of small CUDA projects. The projects had been built using CUDA6.0/VS2013(referencing the VS2012 express platform toolset). All the projects were compiling without error in a second or two and when complied were running correctly.
Two weeks ago I install CUDA6.5rc and reconfigured one of my previously successful projects to use CUDA6.5rc with the VS2013 platform tool set. Kicking off the compile I initially thought it had hung however after more than four minutes the compile completed without error and the resultant programme runs correctly. I have tried several other projects and they also now experience the long compile time but when complete work correctly.
I have subsequently reset the project configurations back to CUDA6.0/VS2013(referencing the VS2012 express platform toolset) and the long compile time now affects the old configuration.
The system I am using is a multi cpu DELL T5400/SSD/16GB/K4000
Task Manager reports that no processes get above 1% during the compile, indeed the only process to report any activity is devenv.exe*32 which reports 1% cpu.
Does anyone have any idea what is causing the slow compile?
