Stop console at error instead continue print 0.00 Mh/s

[YanDevDe]

I'm using AMD Radeon R9 M370X, yes maybe the memory in my GPU is low and may not work, but instead to continue mining at 0.00 Mh/s, the console stop at OpenGL error.

[smurfy]

the errors are:

cl  14:28:44|cl-0      Creating light cache buffer, size 35258176
cl  14:28:44|cl-0      Creating DAG buffer, size 2256527744
X  14:28:44|cl-0      Creating DAG buffer failed: clCreateBuffer -61
X  14:28:44|cl-0      OpenCL Error: clEnqueueWriteBuffer -38

So it looks like it fails to generate the DAG.
How much memory does your card has?

[YanDevDe]

I bet less than 2GB, I know this won't work (because DAG file is huge). And this is not a bug of ethminer.
But I didn't mean this issue because of my gpu, I meant that console should stop print hashrate-speed after OpenCL Error.

[ddobreff]

You can't mine with 2GB ethereum anymore, the DAG size has passed 2GB a while ago. Better try ubiq/exp/music.

[YanDevDe]

Again: This issue isn't about my GPU, it's about that console should stop print hashrate speed after the OpenCL Error (or other errors) appeard.

I already know that I can't mine with my notebook's gpu due less than 2GB memory. This GPU was just a experiment.

[ddobreff]

We already know that, a proper watchdog class is being considered currently.

[piotr-dobrogost]

Please see the following issues:

• issue Command to quit miner on error #97 (Command to quit miner on error )
• issue Handle crashing better #249 (Handle crashing better)
• issue Please add a WATCHDOG function so miner can alert when error occurs. #274 (Please add a WATCHDOG function so miner can alert when error occurs.).

(Maybe some of them should be closed as duplicates?)

[YanDevDe]

issue #97 look duplicated for this issue.

[DeadManWalkingTO]

Unfortunately 2GB GPUs can't mine ETH anymore.

By the way:

After #757 (added --exit parameter to exit whenever an error occurred) you can use a watchdog.

Here is my ETHminerWatchDogDmW Windows7/8/10 [32/64] & Linux (Any Dist/Any Ver/Any Arch) (#735).

Check and feedback please.
Thank you!
