ECP task updates
Roundtable
Rob will help Silvio with a very simple DeviceAdapterAlgorithm::Schedule call that will (hopefully) show the issues on A21 pre with little code.
Matt Larsen has run into an issue with CUDA 11 where it is complaining while compiling DIY that the std:: namespace does not seem to exist. The issue might be related to new CUDA features that support more std objects on devices. As of now, no one has a good solution.
Follow up for benchmarking of Kokkos. Do we have profiling of what is being run during the "slow" filter benchmarks? Sujin is working on changes to the Kokkos device adapter that use Kokkos algorithms like scan and sort for the cases where it is supported. After that we can benchmark again.
Rename master branch?
- Need to wait for some changes to git before the transition (for some automated features of repo).
- Can we for a time have a master that mirrors the new default?
- Don't know, but seems possible. Will have to look into that.
