NVIDIA recognizes MAGMA breakthrough at GTC12
2012-05-20

CUDA Centers of Excellence (CCOEs) include some of the world's top universities engaged in cutting-edge work with CUDA and GPU computing.  To highlight and reward the excellent research, each of the world's 18 CCOEs was asked to submit an abstract describing their top achievement in GPU computing over the past year and a half.  A panel of experts, led by NVIDIA Chief Scientist Bill Dally, selected four CCOEs to present their achievements at a special event during GTC 2012. UTK's CCOE was selected as one out of four CCOE finalists to showcase at GTC12 their work (see slides) on MAGMA: A Breakthrough in Solvers for Eigenvalue Problems (see abstract). 

Each of the four finalists received an HP ProLiant SL250 Gen8 system configured with dual NVIDIA Tesla K10 GPU accelerators

For further information see the NVIDIA press release.
