Is the latest test_gradient_based_solver.cpp correct?

[==========] 240 tests from 24 test cases ran. (39746 ms total)

All tests from test_gradient_based_solver.cpp is failed. What can I do?
I havd run caffe-rc, and all passed.What's the problem?

[chengwang777]

I still have the problem.
int available_devices = 1;
#ifndef CPU_ONLY
/if (Caffe::mode() == Caffe::GPU) {
CUDA_CHECK(cudaGetDeviceCount(&available_devices));
}/
#endif

if I comment the code above, then all tests is passed.
I think if I have only 1 device,all is right.
But I have 4 device, then 66 tests is failed. What can I do?

I also encounter this problem,and there are 16 GPUs in my computer .I have got 70 failed in make runtest. I have already done like this ,set "export CUDA_VISIBLE_DEVICES=0",and instead EXPECT_EQ with EXPECT_NEAR and 1e-4 ,but it does not work!Still showed "src/caffe/test/test_gradient_based_solver.cpp:370: Failure
src/caffe/test/test_gradient_based_solver.cpp:378: Failure"
If you got some methods to deal with these problems,Please notice me,thank you!

[dustcraft]

Okey,i had solved this problem. Thank you.

This was caused by the earlier multi-GPU edition of the tests fixed with the parallelism switch in #4563.
