I have Intel Pentium M HT 3.2GHz, 1 Gb RAM, WinXP 32bit SP3, no OpenCL compatible graphics card (mobility radeon 9700).
I have installed ATI stream SDK 2 beta 4. All samples in the SDK work also the library OpenCL.NET also works for me.
I get this exception when I start the vector addition sample:
System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt at OpenTK.Compute.Cl10.CL.Core.CreateContextFromType(ContextProperties* properties, DeviceTypeFlags device_type, IntPtr pfn_notify, IntPtr user_Data, ErrorCode* errcode_ret)
at OpenTK.Compute.CL10.CL.CreateContextFromType(ContextProperties * properties, DeviceTypeFlags devicetype, IntPtr pfn_notify, IntPtr user_data, Error Code* errorcode_ret) in C:\Users\Stefanos\Desktop\opentk-all\opentk-0.9.9-2b\Source\OpenTK\Compute\CL10\CL.cs:line 1629 at Examples.FFT.Main() in C:\Users\Stefanos\Desktop\opentk-all\opentk-0.9.9-2b\Source\OpenTK\Compute\CL10\VectorAdd.cs
(I've typed the above by hand so I do not guarantee 100% correctness)

This has been fixed in SVN & OpenTK 0.9.9-3 (will be released in an hour or so).
#4
This should have been close a while a go...
