Re: [hpx-users] HPX 1.4.0 release candidate 2
Kor - Ah, I see now. No, step 2 shouldn’t be necessary. Can you provide some more information about your build environment (OS, architecture, compiler, compiler version) and which HPX commit tag you are working with? When you build your application, do you use cmake or configure with pkg-config? It’s possible that your linker is not adding libhpx_apex.so from the HPX configuration output. In addition, can you submit an issue for this on github? We haven’t seen this problem in our tests, but I can see how it might happen. Thanks!

Re: [hpx-users] HPX 1.4.0 release candidate 2
In order to collect and write the OTF2 trace, please set the environment variable APEX_OTF2=1.

Re: [hpx-users] Link error building HPX with support for APEX
Yeah, HPX changed build dependencies without warning, these are now fixed.
You'll need to add an extra option to the HPX config to pull the latest from
APEX:
-DHPX_WITH_APEX_NO_UPDATE=FALSE -DHPX_WITH_APEX_TAG=develop
Thanks -

Re: [hpx-users] TAU support v1.3.0
Karol - Unfortunately, those instructions are out of date.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 - Kevin > On May 30, 2019, at 4:47 AM, Hartmut Kaiser wrote: > > Hey, > > I’m cc’ing Kevin Huck on this email.

Re: [hpx-users] HPX Profiling (TAU?)
Kilian - APEX+OTF should work fine with distributed runs. Are you running the job from a directory where you have write permission? Here are some tips - - OTF requires a "unification" process at the end of the run. Ideally, I would use HPX to do that, but I haven't implemented that. Instead, I use the filesystem. So, each rank will write three (or so) "hidden" files in the current working directory, and rank/locality 0 will read them, unify them, and write out a "master" mapping for the other ranks. - By default, APEX will write the OTF2_archive directory of OTF2 files in the current working directory. - If you want to change the location of either of those two locations, set the APEX_OTF2_ARCHIVE_PATH environment variable before your run, and the files will be written there. The default value for APEX_OTF2_ARCHIVE_PATH is "." (current working directory, relative). Let me know if that works, and/or if you have any other problems.

Re: [hpx-users] HPX Profiling (TAU?)
Kilian - You don't need TAU to generate OTF2 traces directly from APEX. Here is what you need to generate them: Get and build the OTF2 library (straightforward configure/make process): https://www.vi-hps.org/projects/score-p/ Configure HPX with APEX enabled and OTF2 support enabled: cmake -DHPX_WITH_APEX=TRUE -DAPEX_WITH_OTF2=TRUE -DOTF2_ROOT=/path/to/otf2 ... If you want to make sure you have the most recent APEX, you can also add: -DHPX_WITH_APEX_NO_UPDATE=TRUE -DHPX_WITH_APEX_TAG=develop ...but I think the current HPX master uses APEX 2.1.2, which is up to date. After building HPX and your application, set the following environment variable before executing: APEX_OTF2=1 You should see an OTF_archive directory after the run, you can load the APEX.otf2 file in vampir.

Tobias - Sorry for the slow reply - I’m traveling and in all day meetings today and tomorrow. To enable OTF2 output, set the following environment variable before execution: APEX_OTF2=1 You can control the location of the OTF2 archive with APEX_OTF2_ARCHIVE_PATH and APEX_OTF2_ARCHIVE_NAME environment variables, although the defaults are usually sufficient.

Re: [hpx-users] HPX and APEX
Xavi - Yes, set: -DAPEX_WITH_PAPI=TRUE -DPAPI_ROOT=/path/to/papi If that doesn’t work, let me know. The PAPI measurements won’t show up in an OTF trace, but they will be in a final report if you set the environment variable APEX_SCREEN_OUTPUT=1 before running the program. The PAPI support is not as robust as I would like it, but isn’t that always the case? :) Thanks - Kevin > On Dec 5, 2016, at 7:31 AM, Hartmut Kaiser wrote: > > This is something for Kevin to answer.
