[Starpu-devel] Deadlock with starpu_calibrate

[Mathieu Faverge <mathieu.faverge@inria.fr>]

Hello,

Has anyone already experimented deadlocks with the starpu_calibrate 
binary ? It has been running for the last 10 minutes on a node with 3 
K40, and it doesn't seem to make any progress. It is stuck after printing:

$ starpu_calibrate_bus
[starpu][check_bus_config_file] No performance model for the bus, 
calibrating...
[starpu][benchmark_all_gpu_devices] CUDA 0...
[starpu][benchmark_all_gpu_devices] CUDA 1...
[starpu][benchmark_all_gpu_devices] CUDA 2...
[starpu][benchmark_all_gpu_devices] CUDA 0 -> 1...
[starpu][measure_bandwidth_between_dev_and_dev_cuda] GPU-Direct 1 -> 0
[starpu][measure_bandwidth_between_dev_and_dev_cuda] GPU-Direct 0 -> 1

Ian, I know you had the same trouble on the same machine. Did you find a 
solution ?

Mathieu
