Xmaris is optimised for [[https://en.wikipedia.org/wiki/Thread_(computing)#Multithreading|multithreading applications]] and [[https://en.wikipedia.org/wiki/Embarrassingly_parallel|embarrassingly parallel problems]] but there have been some recent investments to improve nodes interconnection communications to enable [[institute_lorentz:xmaris#parallelism_101|multiprocessing]]. | Xmaris is optimised for [[https://en.wikipedia.org/wiki/Thread_(computing)#Multithreading|multithreading applications]] and [[https://en.wikipedia.org/wiki/Embarrassingly_parallel|embarrassingly parallel problems]] but there have been some recent investments to improve nodes interconnection communications to enable [[institute_lorentz:xmaris#parallelism_101|multiprocessing]]. Currently, multiprocessing is possible on maris0[78-81] which are interconnected via an InfiniBand EDR switch. |

Xmaris is the successor of the maris cluster, renamed with a prefix ''x'' because its nodes deployment is automated using the [[https://www.xcat.org/|xCAT]] software. Less formally, the presence of the ''x'' prefix also suggests the time of the year when xmaris was first made available to IL users, that is Christmas (Xmas). | Xmaris is the successor of the maris cluster, renamed with a prefix ''x'' because its nodes deployment is automated using the [[https://www.xcat.org/|xCAT]] software.
