Open source project that needs performance optimizations

[PSATHAS NILOS-HRISTOS]

Hello,
i am an undergraduate student on computer engineering and im  
considering to do my thesis to an open source project and make  
performance optimizations and/or add parallelism to it where possible  
(or even better make use of GPU). Do you think that pspp is a good  
candidate?

Thanks,
