Hi,
I've been using PyCUDA a lot (see http://pynx.sf.net) and I am just
switching to PyOpenCL, which seems to work very nicely, including with CPUs.
Right now I am working under Ubuntu with amd+intel+nvidia sdk's, which seem
to work nicely along each other and PyOpenCL.
Only slightly annoying thing, the intel compiler seems to be a bit verbose
when it does not need to be, e.g. I get messages like:
##########
Build on <pyopencl.Device 'Intel(R) Core(TM)2 Quad CPU Q9550 @ 2.83GHz' at
0x1af72c0> succeeded, but said:
Build started
Kernel <Fhkl> was successfully vectorized
Done.
##########
This is a pretty minor issue, but does someone know how to turn off this
message from the intel compiler (while still keeping real warnings, I don't
want to completely turn off PyOpenCL reporting of messages). I tried looking in
the intel manual, but did not find a compiler option for that.
Incidentally, the intel compiler seems much more efficient (3.5x speed) than
AMD's for my Intel Core 2 Q9550. Not sure why, either better vectorization or
faster sin/cos functions.
regards,
