Application stuck on receive #113

Closed Mellich closed 2 years ago

Application b_eff works in emulation and simulation as expected. ACCL XRT tests succeed with the bitstream (except streaming send/recv which is not used by the application). Application hangs on first receive when executed on hardware.

Run run_mpi.sh in following directory: /proj/xlabs_t3/users/mariusm/runs/2022-10-20-b_eff_accl_test_u55c

Some IP addresses of the ACCL ranks were wrongly set.
