TestCases

To generate test cases, run the Test_Generator.py -N file, where N is the dimenstion of the matrix

How to Run

Run the run.sh script present in each directory to run the experiments.

./run.sh

Individual Run

To compile each program individually, see the run.sh . Preferable method is to comment out unnecessary part of run.sh files.

Plot

Plots can be generated by Gen_Plots.py, exeution time has to be filled manually in the script.

Observation

sgemv

Note : Y_Axis shows exection time in ms, and X_axis shows dimension of matrix [2^i X 2^i]

• sgemv : CPU with 8 thread pools were beating, cuda's Cuda experiments.
• CPU_GO_Single: Single threaded CPU implementation in Go
• CPU_N_THREAD : Multiple threads spawned simpultanously on CPU
• GPU : GPU implementation
• CPU_8_Pooled_THREAD : a pool of 8 worker threads
• CPU_O3 : C code compiled with -O3 optimisation enabled in gcc
• CPU : C code compiled with no optimsation
• GPU_CUBLAS : CUBLAS Library

dtpmv

• GPU : GPU implementation

• GPU_CUBLAS : CUBLAS Library

• CPU : C code compiled with no optimsation

• CPU_O3 : C code compiled with -O3 optimisation enabled in gcc

• dtpmv : cublas impementation was the slowest.

Limitiation

Experiments of matrix above size 1024 X 1024 cannot be performed (on my pc) due to memory limitation.
