Sample code problem?

1st, I'm using SLES 10.

I followed the instruction for installing BROOK+CAL contained in "readme_install.txt" (choosing to install in /usr/local). I then went to the sample code in /usr/local/amdbrook/samples/apps/optimized_matmult and ran "make".   All went fine and a  "built_d" directory was created.  Its contents are listed below:

-rw-r--r--  1 root root 198232 2008-06-23 16:44 common.o
-rw-r--r--  1 root root  20451 2008-06-23 16:44 optimized_matmult.cpp
-rw-r--r--  1 root root  65110 2008-06-23 16:44 optimized_matmult_gpu.hpp
-rw-r--r--  1 root root 627560 2008-06-23 16:44 optimized_matmult.o
-rw-r--r--  1 root root  32840 2008-06-23 16:44 Timer.o

But where's the "a.out" or whatever the executable is named?

Hi jski,

Go up to the samples/bin directory. I believe the makefile put the binaries up there instead of in the directory for cleanliness.

THANKS!  Should have looked in the Makefile (OUTPUTBASE := samples/bin) - duhhh!

I built and ran this (optimized_matmult_d) on an Opteron box with an NVidia Quadro FX 540.  No problems!  I assume it's using the NVidia GPU?

Hi jski,

Most likely you were running using the CPU backend which allows you to run completely on the CPU for easier debugging.

Check your BRT_RUNTIME env variable. Brook+ does not work on NVIDIA GPUs.
