Runtime evaluation of maximum concurrency in DPC++

[danielarndt]

Is there any way to get the maximum number of concurrently active threads at runtime (or at least an upper limit)?

AFAICT, I can only ask for the maximum number of compute units and the maximum workgroup size. Is it safe to assume that there is not more than one workgroup active for every compute unit?

Hi,

We are working on your query and will get back to you at the earliest.

Thanks,

Calculating an upper limit of concurrent thread numbers at runtime would be good enough for me. How would I do that?
Basically, I am looking for something corresponding to cudaDevAttrMaxThreadsPerMultiProcessor.
