Building Phylanx on Rostam

Note: This article only covers the compiling and running of Phylanx on Rostam. To know more about Rostam's hardware, available libraries, or Slurm workload manager, please refer to Rostam wiki.

Libraries

To build Phylanx, you need the following libraries, which all are available on Rostam. Rostam uses a module system to configure the environment for libraries. Rostam modules are written so that loading the module is enough for CMake to find the library. By using the module, you don't need to set CMake flags for the libraries.

HPX

There is a set of pre-compiled HPX available on Rostam. These builds are updated weekly. The following CMake flags are used to compile HPX.

• HPX_WITH_THREAD_IDLE_RATES=ON
• HPX_WITH_THREAD_LOCAL_STORAGE=ON
• HPX_WITH_PARCELPORT_MPI=ON
• HPX_WITH_PAPI=ON

Following builds are available:

Version	Compiler	Mode	Boost	Module	Path
master	gcc 10.2.0	debug	1.73.0	hpx/master-gcc-debug	/opt/hpx/master-gcc-debug/
master	gcc 8.1.0	release	1.67.0	hpx/master-gcc-release	/opt/hpx/master-gcc-release/
master	clang 6.0.0	debug	1.67.0	hpx/master-clang-debug	/opt/hpx/master-clang-debug/
master	clang 6.0.0	release	1.67.0	hpx/master-clang-release	/opt/hpx/master-clang-release/

Note: Loading an HPX module will load all dependent modules.

Example

$ module load hpx/master-gcc-release
$ module list
