CUDA-MEME is a motif discovery software based on MEME (version 3.5.4) algorithm for a single GPU device using CUDA programming model. mCUDA-MEME is an ultrafast scalable motif discovery algorithm based on MEME (version 4.4.0) algorithm for mutliple GPUs using a hybrid combination of CUDA, MPI and OpenMP parallel programming models. This algorithm is a further extension of CUDA-MEME with respect to accuracy and speed and has been tested on a GPU cluster with eight compute nodes and two Fermi-based Tesla S2050 (and Tesla-based Tesla S1070) quad-GPU computing systems, running the Linux OS with the MPICH2 library. The experimental results showed that our algorithm scales well with respect to both dataset sizes and the number of GPUs. At present, OOPS and ZOOPS models are supported, which are sufficient for most motif discovery applications.  The source code is available for download.


  • CUDA-MEME v2.7.4
    1. Avoided the dependence on CUDA SDK, and thus can be directly compiled using CUDA 5.0 toolkit.
    2. Automatically detect the maximum number of resident threads per multiprocessor on GPUs.


Refer to the usage in the MCUDA-MEME page.
