Coalesce command serialization into single MPI op per task and node

2

In addition to execution commands, scheduling a task will generate push / await-push / reduction cascades on participating nodes. So far, all of these implicit commands are `MPI_Sent` to workers...

- As of C++11, integral and floating-point literals can be followed by a user-defined literal - Class and Struct definitions can contain the final, private, protected, public keywords

Allow submitting kernels to an existing CUDA stream

6

In this issue I want to make the case for an API that allows submitting SYCL kernels directly onto existing CUDA streams (or equivalent native backend queue types). This would...

Open SYCL currently [prints warnings and errors to stdout](https://github.com/OpenSYCL/OpenSYCL/blob/67e972bee890eafa3e29243ecac9cb987226a395/include/hipSYCL/common/debug.hpp#L64). These lines mix with any output the user decides to print as part of normal program execution, and any script that...

[IDAG] Communication & Receive Arbitration

This is the second PR in the Instruction Graph series, and the first one to touch the execution side of the new runtime. It adds the necessary infrastructure to perform...

RFC: Implement access::components higher-order range mapper

2

RFC, based on #182. A common parallelization pattern, e.g. in dense matrix-vector products, is to map 1D thread-ids to the rows of a 2D matrix while iterating over all columns...

Platforms for identical devices do not compare equal

### Describe the bug To split work in a multi-GPU setting, we need to find sets of equal / compatible GPUs on a system. On a system with 4x Nvidia...

Create SYCL events for submissions to native queues

2

### Is your feature request related to a problem? Please describe SYCL allows submitting native backend operations to (in-order) queues without paying the synchronization overhead cost of a `host_task` through...

Enhancement: Add an option to move window decorations to the bottom.
