UVaTRMM: Distributed TRMM for commodity clusters

UVaTRMM is an open source C implementation for distributed TRMM (Triangular Matrix-Matrix Multiplication). It leverages MPI to enable distributed memory executions.

Remark: By commodity clusters we mean small systems equipped with, at most, 40 nodes.

Compiling UVaTRMM

$ cd UVaTRMM
$ make all

Dependencies:

• MKL (or equivalent, for TRMM and GEMM kernels)
• MPI (remember to properly link the chosen library)

** Remember to create the directory "exec" for the binaries generated during compilation

Executing UVaTRMM

$ mpirun -np <NumberOfMPIProcesses> exec/uvatrmm.x <MatrixDimension> <reg/balanced> <boxes/trapezoid>

For comparison against ScaLAPACK

We provide ScaLAPACK GEMM and TRMM sample codes ready to be compiled and compared with our implementation.

Compile them with:

$ cd ScaLAPACK
$ make
