Slow program termination NVIDIA GPU mode

[Angel996]

Hello.

Ubuntu 16.04 LTS.

I have noticed miner takes very long to terminate: be it CTRL-C in terminal, or killall command. Terminal appears frozen, not reacting up to 30 seconds. In a scenario where we do multi-algo mining, switching miners etc this poses a bit of a problem.

Problem is only Nvidia GPU related. If I run CPU only mining or AMD GPU mining, miner terminates fast, although also appears frozen for 1-2 secs.

thanks. ))

In my case the entire rig freeze when I close xmr-stak, and I have to reset the machine

Try the new release and let us know if it's resolved.

i've trouble building it on ubuntu 17.4 with cuda8. VArious issues with both Gcc 5 6 or 7.. /home/mirko/miner/xmr-stak/xmr-stak/xmrstak/version.hpp:13:33: error: 'to_strin' is not a member of 'std'

still have to find a solution..

JerichoJones, just tried the new release, and couldn't get it working at all. Also, there is a weird thing going on with pool logon, miner only logs in after several attempts: I specifically rechecked: older version does not have this problem.

Little update. Deleted the old nvidia.txt and cpu.txt files. Now it runs for some time, but terminates again with this error:

[CUDA] Error gpu 0: </home/user/xmr-stak/xmrstak/backend/nvidia/nvcc_code/cuda_extra.cu>:266
terminate called after throwing an instance of 'std::runtime_error'
  what():  [CUDA] Error: the launch timed out and was terminated
Aborted (core dumped)

Deleted old config.txt file and let miner recreate it. Now, it's running.

Seriously, guys, you are making it SO HARD with all those config files... I already opened another issue concerning running the miner w/o the config file. They add so much confusion. No other miner requires having a config file. However, xmr-stak won't run w/o it, and would instantly crash if config file is not the right version/format.

reduce the thraeds in nvidia.txt

[fireice-uk]

@Angel996 that's why it will create one for users that find them confusing.

[Angel996]

I don't find them confusing, they add much confusion to usability of the miner. If every new miner release requires all new config files, maybe it would be a good idea to re-create them or warn user. Instead of terminating with segmentation fault messages.

My idea is, user should be able to run the miner with command line parameters ONLY. Let the miner create any files it wants. At the moment, it is not the case. There is no way to specify TLS handshake on the command line. There is no way to specify coin (Monero/Aeon).
