ROMERO-VIVAS, Eduardo; VON BORSTEL, Fernando D.  e  VILLA-MEDINA, Isaac. Analysis of Genetic Expression with Microarrays using GPU Implemented Algorithms. Comp. y Sist. [online]. 2013, vol.17, n.3, pp.357-364. ISSN 2007-9737.

DNA microarrays are used to simultaneously analyze the expression level of thousands of genes under multiple conditions; however, massive amount of data is generated making its analysis a challenge and an ideal candidate for massive parallel processing. Among the available technologies, the use of General Purpose computation on Graphics Processing Units (GPGPU) is an efficient cost-effective alternative, compared to a Central Processing Unit (CPU). This paper presents an implementation of algorithms using Compute Unified Device Architecture (CUDA) to determine statistical significance in the evaluation of gene expression levels for a microarray hybridization experiment designed and carried out at the Centro de Investigaciones Biológicas del Noroeste S.C. (CIBNOR). The obtained results are compared to traditional implementations.

Palavras-chave : GPU; microarray; CUDA.
