The ubiquitous MPI environment in HPC cluster + Work Stealing Pattern + Distributed Termination Detection = Efficient and Scalable Parallel Solution.

pcircle contains a suite of file system tools that we are developing at OLCF to take advantage of highly scalable parallel file system such as Lustre and GPFS. Early tests show very promising scaling properties. However, it is still in active development, please use it at your own risk. For bug report and feedbacks, please post it here at https://github.com/olcf/pcircle/issues.

• cmake3 This is available through Redhat EPEL Repo. Once it is enabled, yum install cmake3.

• A working C++11 compiler.

• A working MPI dev environment. For RHEL7, that means:

  sudo yum install mpi-devel
  module load mpi 
  

  git clone http://github.com/olcf/pcircle
  
  cd pcircle; ./buildme.sh      

This should build the fprof binary by default in the build directory.

  mpirun -np 8 fprof /path/to/directory
