[petsc-dev] Possible bugs when using TS with ViennaCL (continued)

[Mani Chandra]

Sorry, you're right. Indeed even when I use the Intel OpenCL to run on the
CPU, the memory usage keeps increasing as the run progresses but the CPU
RAM is so much that the run doesn't crash till the time I ran it. So
basically there is a memory leak.
