Cloo

I just noticed that clootils has not worked from revision 189c292377f4f29b32ef8ac150387cd1847ff78e. It throws a Cloo.InvalidValueComputeException in ComputeObject.cs at line256. It was apparently thrown by the type initializer for Cloo.ComputePlatform. I noticed this problem in the head revision and worked backwards until I found one that worked. The revision mentioned above is the oldest one throwing this error. I wish I could upload error screen shots here. The stack trace is about 30 lines.

The only thing I can think of is the absence of support for the cl_khr_fp16 or cl_khr_fp64 extensions. If yes this is a bug. I cannot reproduce it but you could try something yourself. Comment out these two lines in ComputeDevice constructor and see if it works: preferredVectorWidthHalf = GetInfo<uint>(ComputeDeviceInfo.PreferredVectorWidthHalf); preferredVectorWidthDouble = GetInfo<uint>(ComputeDeviceInfo.PreferredVectorWidthDouble);

Edit: Now that I think of it it's easier to assign a zero. Commenting them out will lead to compiler errors.

That seems to have fixed it. In my particular case, only the line preferredVectorWidthHalf = GetInfo<uint>(ComputeDeviceInfo.PreferredVectorWidthHalf); was causing a problem. The line dealing with doubles works fine.

I am getting an IOException on line 92 of ComputeEvent.cs (the writeLine statement). The code is marked to only run in debug mode, so this might not be a problem. Oddly enough, I only get his error if the OpenCL tests have been run. Just opening and closing the window works fine.

0.8.1 is out. This bug was quite critical so I decided to update the package. Thank you very much for your help, kwaegel!

Glad I could help. I am using Cloo as part of an independent study in collage (hardware accelerated ray tracing), so it is to my benefit to help get some of the bugs out...
