Karol -
Unfortunately, those instructions are out of date. There is no HPX/TAU
integration any more.
Instead, what you can do is use APEX to interface with TAU.
Remove these CMake options:
> -DHPX_WITH_TAU=TRUE \
> -DTAU_ROOT=$HOME/libs/tau-2.26 \
> -DTAU_ARCH=x86_64 \
> -DTAU_OPTIONS=-mpi-pthread \
And keep/use these CMake options:
> -DHPX_WITH_APEX=TRUE \
> -DAPEX_WITH_ACTIVEHARMONY=TRUE \
> -DAPEX_WITH_PAPI=FALSE \
> -DAPEX_WITH_MSR=FALSE \
> -DAPEX_WITH_OTF2=FALSE \
> -DACTIVEHARMONY_ROOT=$HOME/packages/harmony/ \
After configuring and building HPX, build TAU with:
git clone https://github.com/UO-OACISS/tau2.git
cd tau2
./configure -mpi -pthread -bfd=download
make install
Then add the TAU bin directory to your path (see the message at the end of the
"configure" step).
Then, to run the program, do:
export APEX_TAU=1
tau_exec -T mpi,pthread -ebs
APEX will measure the HPX tasks, passing them to TAU as timers. TAU will also
use event based sampling (-ebs) to periodically sample the program to build a
hybrid timer/sample profile. You can then load the profiles into the TAU
program "paraprof" to visualize the data.
If you have access to the Vampir trace analysis tool, you can also just use
APEX by itself to measure the program. In that case, you would need these HPX
configuration options:
-DAPEX_WITH_OTF2=TRUE \
-DACTIVEHARMONY_ROOT= \
...and you would set APEX_OTF2=1 before running the program to generate an OTF2
trace for Vampir. The OTF2 library can be found here:
https://www.vi-hps.org/projects/score-p/ OTF2 is easy to build with "configure
--prefix=/path" and "make && make install".
Let me know if you run into any problems.
Thanks -
