SURFsara's Life Science Grid (LSG) is a distributed cluster computing environment for large-scale data analyses or simulations, in particular suitable for multi-centre studies that require a private virtual organisation or calculations that require large amounts of compute resources. It offers 128 compute cores, a total of 512GB memory and 10TB scratch space for temporary datasets. For the preparation of input and output datasets a storage element is available with a net capacity of 40TB.
The LSG cluster allows for the execution of 128 simultaneous single-core jobs. The cluster is integrated in the EGI grid infrastructure allowing for scalability to computer resources in Europe and within the We-NMR consortium.
Apart from the standard functionality offered by Grid clusters all over the world, the cluster allows users to have access to the cluster via a local user interface machine on which they develop, compile, test their code, as if working on a local cluster.
The Utrecht group has been operating a Grid site integrated into the EGI infrastructure since over 6 years, before switching to the LSG solution offered by SURFsara. Operating such a Grid site is quite demanding in terms of system administration with frequent updates, certificate renewals, etc., next to keeping the hardware state-of-the art.
Switching to a LSG cluster means much less burden on the research group at the Bijvoet Center. They can now concentrate on the science and the operation of the WeNMR web portals running in Utrecht, and in particular the HADDOCK portal which has been sending over 6 millions jobs to the Grid last year.
