tests: test-backend-ops -j <N> to run tests in parallel#23637
Merged
Conversation
Create a pool of N threads that grab a chunk of up to 100 tests at a time to iterate through. The number of tests at a time decreases as fewer remain. Each thread uses its own dev and cpu backend, and set_n_threads_fn is not called on the cpu backend. Fix some TSAN issues that arose: - In init_tensor_uniform, don't use static vector of generators. - Replace gmtime with versions that don't use a global variable. - Mutex calls to print_test_result.

Nice - should utilize this in the CI runs in a follow-up PR

Overview
Create a pool of N threads that grab a chunk of up to 100 tests at a time to iterate through. The number of tests at a time decreases as fewer remain.
Each thread uses its own dev and cpu backend, and set_n_threads_fn is not called on the cpu backend.
Fix some TSAN issues that arose:
This should be TSAN clean, at least running CPU backends.
Timings on my system (singlethreaded -> large N):
vulkan (with shaders cached) 3:10 -> 1:47
cuda 2:15 -> 0:55
There are locking issues in ggml-vulkan that prevent scaling when pipelines are being compiled, which I'll fix separately.
#23595 will help a bit with scaling (fixes a big stutter at the start). #23376 will help with vulkan.
