Re: [moose-devel] An error in testHSolve.py

[saeed <sa...@gn...>]

Dear Subhasis,

    Application crashes with Assertion failure in SpikeRingBuffer.cpp:63
    and actually I just put the warning to maybe guide to the problem.
    My change is not about the dt, after just a little increase in
    simulation time (from 0.01 to 0.1) I see this problem. I am
    wondering, maybe SynChan is not working properly. I know that the
    HSolve is still under control, but in other side I finished the GPU
    implementation and for accuracy test, I need to make the Moose work.

    It would be my great pleasure if you direct the issue to the
    responsible developer.

    Thank you in advance.
