SciCloud

SciCloud project studies the establishment of private clouds, migration and execution of scientific computing applications on the cloud, and adapting scientific computing problem/algorithms to frameworks amicable to the cloud like the MapReduce.

Cloud computing has become quite popular in the distributed computing community and to study the cost of science on the clouds, Scientific Computing Cloud (SciCloud) project has been initiated at the University of Tartu. Its main goal is to study the scope of establishing private clouds at universities. With these, students and researchers can efficiently use the already existing resources of university computer networks, in solving computationally intensive scientific, mathematical, and academic problems. The project targets the development of a framework, including models and methods for establishment, proper selection, state management (managing running state and data), auto scaling and interoperability of private clouds.

SciCloud has been established on our high-performance computing (HPC) clusters using the Eucalyptus technology. Current research in the domain is focused at studying the cost of migrating scientific computing applications to the cloud. SciCloud has several customized machine images with support for several scientific computing tools and simulations like Python with NumPy and SciPy, Scilab tool, MPI. Detailed analysis with several benchmark applications like matrix-vector multiplications and NASA Advanced Supercomputing parallel benchmarks (NAS PB) are performed using the setup.

Moreover, to adapt resource-intensive scientific computing applications for the cloud, the applications must be reduced to frameworks that can successfully exploit the cloud resources. Generally, cloud infrastructure is based on commodity computers, which are cost effective, however are bound to fail regularly. This causes a serious problem as, the software has to adapt to failures and the best solution is to replicate the data and computation. One such framework that is built based on this idea is the MapReduce framework, which has gained popularity as a cloud computing framework on which one can perform automatically scalable distributed applications. SciCloud project studied reducing several scientific computing problems/algorithms to MapReduce and designed a classification, based on how the algorithms are adapted to the MapReduce framework.

SciCloud Infrastructure

SciCloud is also the name of the private cloud infrastructure running on the hardware of the University of Tartu. It is divided into separate smaller clouds built using Eucalyptus/OpenStack platforms. Both Eucalyptus and OpenStack are open source cloud platforms compatible on the API level with Amazon EC2 public cloud.
