From May 5th to 10th, I was in Aspen, CO attending my first C++Now conference. I was able to participate as a student volunteer, and I was able to give a lightning talk about C++ Distributed Object Abstraction using HPX.

Compiling and Running Blazemark
By Shahrzad Shirzad
Blazemark is the benchmark suite for Blaze library. In order to compile and run Blazemark with HPX backend, take the following steps:
- Change the Configfile at
blaze/blazemarkby filling in theCXX=,CXXFLAGS=,LIBRARY_DIRECTIVES=fields in the Configfile:
This is an example of the configurations used for Clang:
# Compiler selection
CXX="clang++"
# Special compiler flags
CXXFLAGS="-O3 -march=native -std=c++17 -stdlib=libc++ -DNDEBUG -fpermissive -DBLAZE_USE_HPX_THREADS -isystem /hpx/install/path/include -Wl,-wrap=main"
# Library settings (optional)
# In some cases it might be necessary to specify additional library paths and add additional
# libraries. This can be done via this setting.
LIBRARY_DIRECTIVES="-L/hpx/install/path/lib/ -lhpx -rdynamic /hpx/install/path/lib/libhpx_init.a -ldl -lrt -lhpx_wrap - L/boost/install/path/lib -lboost_system -lboost_program_options" - ./configure Configfile
- make benchmark_name
- ./bin/benchmark_name
Notes:
- You can change vector or matrix sizes to run the benchmark on through the benchmark_name.prm file located at
/blaze/blazemark/paramsfolder.
For more information on available benchmarks, command line parameters, and also the list of supported libraries please visit Blazemark.

Joining the Team: Searching for Postdocs!
The STE||AR Group at LSU is excited to announce a search for a postdoctoral researcher. We are looking for a team member with strong C++ skills and experience and an interest in high performance computing, runtime systems, or machine learning. Familiarity with the paradigms and constructs of
Joining the Team: an REU experience
2018 is proving to be an exciting year for the STE||AR Group. We anticipate hiring more people this year to help us work on the many new projects we and our collaborators have received. These new rolls include positions for people who are just starting their coding career. Over the summer, the STE||AR
CppChat: On Air with HPX
This past week members of the HPX team were invited to give a talk on Jon Kalb’s weekly CppChat. Bryce Adelstein-Lelbach, Hartmut Kaiser, Thomas Heller, and John Biddiscombe were invited onto the show to talk about HPX, our programming
