[Possible fix] Gaussian blur dots missing on performance graphs #51

Open wh1114 opened 6 years ago

wh1114 commented 6 years ago

After you have run the test this morning, there are a few performance graphs that don't have any dots on it.

Would this indicate there are bugs in the programme that stops it from completing the test, or the time the programme is too long and the programme was automatically suspended?

We are also having the same issue with Gaussian Blur :(

same issue with gaussian blur.

It could mean either that the program crashed, or that it took to long. If you look at the logs, rather than the graphs, there may be more information (though there is a limit to how much information can be captured in the tests, so I can't guarantee it).

If you have dots for some puzzles, but not for others, then it is something local to that puzzle itself.

I noticed that this might be caused by kernel files. My kernel file was working fine on my PC, but when I tried to run it on the g2.2large instance, it would not compile. An extra line

pragma OPENCL EXTENSION cl_khr_fp64: enable

Has to be added for double precision floating point numbers. This might be what was causing the trouble considering many of the issues are relative to Gaussian Blur.
