Cloo : Stream SDK v2.0 error

The project is still in alpha stage. Because of time constraints, I haven't been able to test every code path.
This looks like a decent bug. Thanks for the report, I'll check things.

I am also getting the same error as CodyIrons using the final release of the ATI Stream SDK 2.0 at the same spot using

ComputeContext.PropertiesDescriptor pd = new ComputeContext.PropertiesDescriptor( ComputePlatform.Platforms[ 0 ] );
ComputeContext context = new ComputeContext( DeviceTypeFlags.DeviceTypeDefault, pd, null );

as suggested.

On my system, I have an AMD cpu but no OpenCL enabled graphics card. I'm running Windows 7 64bit and using Visual Studio 2008 with Cloo 0.4.1. The ClooInfo program works, but any sample that tries to set up a context fails with an invalid platform error.

I was using Cloo 0.3.1 and Beta 4 of the ATI Stream SDK 2.0 before I installed the new versions and they worked like a charm.

Okay, some more (and interesting) info on this problem......The ATI samples in the SDK 2.0 final won't even run and they are not using CLOO! I get a "Error: clCreateContextFromType failed. Error code : CL_INVALID_PLATFORM" message when I try running them. I've even tried uninstalling and reinstalling the SDK and it didn't do anything. I've now reverted back to the SDK 2.0 Beta 4 and all CLOO code works as expected, even using the additional device code suggested here. However, the ATI Stream SDK 2.0 final samples don't work on the Beta: I get a "Error: clCreateContextFromType failed. Error code : CL_INVALID_PLATFORM"

I suspect this is a bug with the SDK itself. Hopefully, we get to the root of this. I'll try posting a thread in the AMD GPU forums in a little bit to ask for help.

Reverting back to sdk 2.0 beta 4 allowed the program to execute properly. But when printing out devices and device counts and platforms, only one platform is found and only 1 device is found (My processor).

I have two versions of the program i'm running, one is for Cloo and one is just using OpenTK. The OpenTK only program i can switch my DeviceTypeFlats.DeviceType from Cpu to Gpu and i see the performance change accordingly:

unsafe
            {
                hContext = CL.CreateContextFromType(
                                   (ContextProperties*)null,
                                   DeviceTypeFlags.DeviceTypeCpu,
                                   IntPtr.Zero,
                                   IntPtr.Zero,
                                   &error);
            }

But on my Cloo version i noticed that the only DeviceType that works is Cpu (between those two):

            ComputeContext.PropertiesDescriptor pd = new ComputeContext.PropertiesDescriptor(ComputePlatform.Platforms[0]);
 
            ComputeContext context = new ComputeContext(DeviceTypeFlags.DeviceTypeAll, pd, null);
            System.Console.WriteLine("NumDevices={0}", context.Devices.Count);

And actually setting the DeviceType to Gpu gives me a 0 number of devices and a System.ArgumentOutOfRangeException when trying to create the Queue.

In the Cloo source for ComputeContext in your GetDevices() method I noticed your only returning 'valid' devices. Is it possible the other devices are being 'weeded out' here?

Most Excellent!! I can confirm it worked on stream 2.0 beta 4 will be trying out the release version after this.

Edit:
Can't create a context with ati's 2.0 release version. You can query for the info and get platform and device info, but you can't create a context. I'm going to revert back to beta 4 to do some playing.
