If you load one of the fosscuda (module load fosscuda/2020b), you can see the other You can run 'module spider toolchain/' to see the versions we have: Tk: Tk is an open source, cross-platform widget toolchain that provides a library ofīasic elements for building a graphical user interface (GUI) in many different programming Gcccuda: GNU Compiler Collection (GCC) based compiler toolchain, along with CUDA toolkit. Recently made free by Intel, we have more experience with OpenMPI than Intel MPI. Iomkl: Intel Compiler Suite, providing Intel C/C++ and Fortran compilers, Intel MKL & OpenMPI. Recently made free by Intel, we have less experience with Intel MPI than OpenMPI. Intel: Intel Compiler Suite, providing Intel C/C++ and Fortran compilers, Intel MKL & Intel OpenMPI for MPI support with CUDA features enabled.
Gompic: GNU Compiler Collection (GCC) based compiler toolchain along with CUDA toolkit, including
Gompi: GNU Compiler Collection (GCC) based compiler toolchain, including OpenMPI for MPI Support, OpenBLAS (BLAS and LAPACK support), FFTW and ScaLAPACK.įosscuda: GCC based compiler toolchain _with CUDA support_, and including OpenMPI for MPI These toolchains include (you can run 'module keyword toolchain'):įoss: GNU Compiler Collection (GCC) based compiler toolchain, including OpenMPI for MPI We provide a good number of toolchains and versions of toolchains to make sure yourĪpplications will compile and/or run correctly. Some software functions better when using specific toolchains. Mpirun python /path/to/hello_world.py ToolchainsĪ toolchain is a set of compilers, libraries, and applications that are needed toīuild software. Source /path/to/virtualenvs/test/bin/activate Here is a simple job script using MPI with Python: Know which one will execute its print statement first. Is because 5 separate processes are running on different processors, and we cannot If you try this example, the output may not be in the same order as shown above. The output will be similar to the following: Mpiexec -n 5 python hello_world.py # run 5 processes Load the module of Python3 and the virtual environment in which you install the "mpi4py", Print("Hello world from node", str(name), "rank", rank, "of", size) Size = comm.Get_size() #gives the total number of ranks Rank = comm.Get_rank() #gives identifier of the processor which currently executing Name = MPI.Get_processor_name() #get the processor's name
In this section, let's create a Python3 script named hello_world.py.Ĭomm = MPI.COMM_WORLD #get the information about all the processors run script
