Got Concurrency::runtime_exception Please Help

Question

Hi Smart People!

Im trying to convert my C++ code to C++ AMP code.

Here is the error i got,

"The number of writable arrays/array_views referenced in the entry function of the parallel_for _each call(11) exceeds the selected accelerator's limit of maximum number(8) of writable buffer views allowed in a lernel."

I have 11 array_view in my code,and got this error.

Do i have any option to avoid this problem?

Or How Can I to set "READABLE" to the array_view?

i need only 1 array to be writable for now.

Answer 1

SELF SOLVED.

thank you guys! I have solved this problem myself.

Im so damb,it just I put "const" in <> .like this

array_view<const float ,1> xxxx(xxxx);

then the array_view be READ ONLY(SRV).

Hi HotInCool

Yup, you found it.

Just for reference, the limit of 8 writeable buffers is increased to 64 if you are running on Windows 8.
