Non-working CGNR iterative solver in OpenCL mode #198

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
There was an error in conjugate-transpose part (her=true) of matvec product for 
a long time (at least from release 1.1). This part is used only in CGNR 
iterative solver. Moreover, it was negligible for a sphere, so a different 
shape (with different volume fraction of a computational grid) is required to 
notice it (that's why it was not noticed by automatic tests).

For example, simple test is 'adda_ocl.exe -iter cgnr -shape box', which causes 
convergence failure.
