Coarray fortran stencil code fails for certain numbers of images #99

Closed rfvander closed 8 years ago

rfvander commented 8 years ago

@afanfa Even though I request only 5 images, the stencil kernel thinks there are 6.

@rfvander ,

it is a consequence of the code deactivated by #98. I'll see to fix this issue.

jeffhammond commented 8 years ago

Sorry, I guess my bug fix was actually bug transmutation :-(

afanfa commented 8 years ago

Hi, I've got a solution for the bug described by #97; I plan to clean the code and make it more efficient during the long weekend. I think you can also close this issue.

Cheers, Alessandro

jeffhammond commented 8 years ago

@afanfa Glad to hear that, but I want to close the issue when we merge the fixes. I like to follow procedure 😄

jeffhammond commented 8 years ago

We merged, so this will be closed.
