Claudia de Molina, Estefania Serrano, Javier Garcia-Blas, Jesus Carretero, Manuel Desco, Monica Abella
2018 BMC Bioinformatics  
Iterative methods may compensate for the lack of data by including additional prior information, although they imply a high computational burden and memory consumption.  ...  Forward-and back-projection operations represent 60% of the total computational burden.  ...  Nevertheless, this work was applied to full span data with a high number of projections. Focusing on the problem of limited data, Jia et al.  ...

Exploiting just-enough parallelism when mapping streaming applications in hard real-time systems

Jiali Teddy Zhai, Mohamed A. Bamakhrama, Todor Stefanov
2013 Proceedings of the 50th Annual Design Automation Conference on - DAC '13  
It has been shown that the various forms of parallelism in an application should be explored to achieve the maximum system performance.  ...  The experiments on a set of real-life streaming applications demonstrate that our algorithm results, within reasonable amount of time, in a system specification with large performance gain.  ...  An example of an exact allocation algorithm is proposed in [16] , which returns an optimal allocation of actors. One disadvantage of using an exact algorithm is its high computational complexity.  ...
