DuctTeip

DuctTeip is a framework written in C++ for task based parallel programming in distributed environments. It uses MPI for communication and inter node parallelism, and SuperGlue framework for shared memory multi-core parallelism. SuperGlue is another C++ task based parallel programming framework that can be found in SuperGlue git repository.

Installation and Build

• Clone both the DuctTeip and SuperGlue repository to local paths.
• Edit the Makefile in the Prototype folder such that the SUPERGLUE_DIR points to the local path where the SuperGlue framework is cloned.
• Ensure that MPI environment settings are available. (Load the module, if you compile in cluster environments)
• Run make where the Makkefile exists. Two debug and release versions of DuctTeip library are produced at ./lib and ./lib/release directories, corrspondingly.

Build the examples

To build and run the examples that exist in the sub-directories of the cloned repository:

• Edit the Makefile such that the DUCTTEIP_DIR and SUPERGLUE_DIR point to the places where these frameworks are copied.
• Run make to get the compiled output

Runtime command line flags used by DuctTeip

Flags (prepended with a '-')	Meaning
P	Total number of processors
p	No. of processor in rows, in grid topology
q	No. of processor in columns, in grid topology
M	No. of elements of input matrix in row
N	No. of elements of input matrix in columns
B	No. of blocks at DuctTeip level
b	No. of blocks at SuperGlue level
t	number of threads at each computing node
DLB	Use Dynamic Load Balancing for task execution at DuctTeip level

In progress and Future Works

• Improving Dynamic Load Balancing
• Including the Unified Task Programming
• Implementing 3D Fast Multipole Method in distributed environment
