ASReml-R: Where Speed Meets Accuracy

ASReml-R is statistical analysis software that offers advanced capabilities for analysing complex data sets. ASReml-R fits complex models faster. Whether it's thousands of levels, multiple environments or traits, or dense relationship matrices, ASReml-R has you covered.

ASReml-R 4.2 - processing speed gains

ASReml-R 4.2 delivers impressive gains in processing speed. These gains depend upon a variety of factors including: microprocessor, machine power, dataset size and type of analysis run, among others, and they will vary between users. Below are some example gains the ASReml team were able to quantify.

Additional notes: Computer specifications: Intel(R) Core(TM) i7-3770K CPU @ 3.50GHz, 16 Gb of RAM, Ubuntu 20.04 LTS.  Analyses were carried out setting asreml.options(threads = 1, use.blas = “standard”) in ASReml-R 4.2. Further speed improvements can be achieved by increasing the number of threads and enabling Intel’s Math Kernel Library (MKL).
