@vinser52 shouldn't you uncomment INSTANTIATE_TEST_SUITE_P(umfIpcTest) in test/providers/provider_cuda.cpp?

I tried to do that, but CUDA cuIpcOpenMemHandle API is more restrictive comparing to L0. It does not allow (as I understand) to open IPC handle in the same context, but tests in ipcFixture.hpp use the same context.

So, in a separate PR, we can enable the abovementioned tests when we resolve the issue I described. It looks like ipcFixture.hpp should be changed to use different GPU contexts.
