[ROCm/rccl commit: c61152baa4]
When the `roc-obj-ls` executable fails, it sometimes does not return. Since the `execute_process` command will wait until the executable finishes, this means that in some cases, the build will hang indefinitely. There is no error message, and no indication that anything is wrong. This commit fixes that by introducing timeouts into the code and better error reporting.
[ROCm/rccl commit: 2482d1475f]
* Add fault injection of starting warps with random variations
This is done by inserting randomly delays after __syncthreads().
The feature can be turned off by FAULT_INJECTION=OFF in cmake.
* Remove manually introduced bug for demo purpose
* Use only one thread per warp for checking wall clock
[ROCm/rccl commit: 90ad586d94]
