ubuntu reboot suddenly

[5440...@qq.com]

Hello
I have met a strange problem. And I have costed 2 weeks to search for a solution.
I used the rcnn(https://github.com/rbgirshick/rcnn) which call caffe's library , but the computer reboot itself suddenly.
Below is my experiments infomation.
1, ubuntu 14.04
2, cuda 6.0
3, Geforce Titan black
Can anyone help me?


PS:
1, I have monitor the GPU use rate, graphic card mem, CPU use rate, memmoy, EVERYTHIN is ok except the CPU use rate is 100%
2, I have located the error code "caffe('forward', batches(j))"!!  But I don't know how to fix it.
3, I have tried to reduce the batch_size to 64, but no lucky !!

It's possible this is a power supply issue.  Are you sure yours is sufficient?  And how do you have your Titan black connected in terms of power cables/rails?

It is also likely that something overheated. I've got my GPU roasting my southbridge a few times due to bad airflow in the box (I had a microATX), and I had to install a better heatsink.

Thank you for answer.
But how can I make sure my power is sufficient?

Thank you for answer.
I have monitor the GPU temprature, I think GPU is not overheated

Comparing rated power supply capacity to the sum of rated TDP for key system components like CPU, GPU, HDD, and memory would be a good start.  But also check how you have the PCIe power cables hooked up to your Titan Black; using cables from separate power rails, if applicable, is best, and also prefer 8-pin over 6-pin when possible.

Same here using caffe-future. I've tried different combinations of hardware and cuda but no luck. Have you solved it?
