This paper presents the performance uation results of the cluster Venus ALTLIX-450. Details are given both its architecture as the libraries available for use. The expected uation of results should register, according to the NACAD, a performance up to 6 GFLOPS per core supported for the NAS Parallel Benchmark benchmark NPB.-This paper presents the performance　uation results of the cluster Venus ALTLIX-450.
