This patch is to address: #11448 When Open MPI is compiled with CUDA support, comm->c_coll->coll_xxx_module is coll_cuda_module and HAN_LOAD_FALLBACK_COLLECTIVE is a no-op. As a result, HAN's collective functions can be called even if HAN has been disabled, which resulted an infinitely recursive calling loop. To address this issue, this patch make HAN's collective fucntion to call fallback function when HAN module was disabled. Signed-off-by: Wei Zhang <[email protected]>

Instead of calling the communicator collective module after disqualifying HAN call directly the fallback collective. This avoids circular dependencies between modules in some cases. However, while this solution works it deliver suboptimal performance as the withdrawn module will remain in the call chain, but will behave as a passthrough.

…eting a request" This reverts commit b6467d0. The change breaks some persistent op implementations, which do not reinitialize the request object.

Similar to open-mpi/ompi-scripts@7dc912e, add "--bind-to none" to the mpirun command. The CI tests on the AWS jenkins instance all run on instances with 1 core. There's a special case in OMPI to bind to core for a 2 process run for benchmarking reasons, and this was causing failures in mapping because there aren't 2 cores on the instance. So instead turn off binding for these small tests. Signed-off-by: Jeff Squyres <[email protected]>

Clean the workspace after every stage (ie, test) to avoid filling disk. The downside of this change is that we can't reuse a checkout of OMPI between stages that run on the same build node. The upside is that we are much less likely to run out of disk space during a test. We ran into some issues today when there were many builds, because the workspace name is different between pull requests, and when a build node had enough checkouts (one for each pull request), we filled the disk.

This patch try to use 1.18 API when it is available. This is because 1.18 API clearly define provider's CUDA API behavior to be that provider can call CUDA API by default if application uses 1.18 API. When using older version of API, some libfabric will not claim support of FI_HMEM even if it is capable of supporting because the provider does not know whether CUDA calls are permitted.
