## Summary
- Fix `run-remote.sh` to correctly execute multi-command scripts (e.g.,
multiple `mpirun` calls)
- The old approach piped decoded script through `base64 -d | bash`,
which feeds the script via bash's **stdin**. When `mpirun` (or its child
processes) runs, it can consume the remaining stdin, causing bash to
never see subsequent commands — only the first command would execute.
- The fix decodes the script to a **temp file** and runs `bash -euxo
pipefail "$TMP"` instead, so bash reads commands from the file and
`mpirun` consuming stdin has no effect.
- Applied to both the docker path (pssh + docker exec) and the
non-docker path (pssh only).

- Removes the GTest dependency, replacing it with a minimal custom
framework (`test/framework.*`) that covers only what the tests actually
use — a unified `TEST()` macro with SFINAE-based fixture auto-detection,
`EXPECT_*`/`ASSERT_*` assertions, environments, and setup/teardown.
- `--exclude-perf-tests` flag and substring-based negative filtering
- `MSCCLPP_ENABLE_COVERAGE` CMake option with gcov/lcov; CI uploads to
Codecov
- Merges standalone `test/perf/` into main test targets
- Refactors Azure pipelines to reduce redundancies & make more readable

* Add a FIFO test code that reproduced a correctness issue
* Fix the correctness issue by using pinned memory instead of cudaMemcpy

1. use `fence+relaxed` to replace `release` for fifo. `fence+relax` is
more efficient on A100
2. Update the deviceSyncer. Previous one cannot handle threadBlock
number change correctly. Use three counters to solve this issue. Reset
previous counter before sync on current counter.
3. Introduce relaxedWait which can be used with relaxedSignal for case
doesn't need guarantee the memory visibility
Now build images by a script with a shared Dockerfile template

- remove `#include <cstdint>` from `poll.hpp`. To make it only contains
device-side code
- Fix compilation issue, which will cause pytest fail randomly. Reuse
the compiled result for same kernel with different arguments
