XSEDE Information for Boston University Users
The Scientific Computing and Visualization group (SCV) at Boston University maintains four computer systems (cluster, SMP and MPP) to provide high performance computing, without charge, to our research community. On occasions, a research project may have special needs (such as runtime of more than 72 hours or memory in excess of 96 GBytes) that are not adequately served by our local systems. For those projects, the external resources provided through the XSEDE program may be appropriate.
What is XSEDE?
XSEDE (eXtreme Science and Engineering Discovery Environment) is the follow-on NSF initiative to Teragrid (which had a primary goal of providing free compute cycles to US researchers) to expand its mission to facilitate research collaboration among institutions, enhance research productivity, provide remote data transfer, and enable remote instrumentation, to name a few.
What resources are available?
This page gives a list of XSEDE resources that might meet your needs.
How do I apply for XSEDE allocations ?
- Who qualifies?
The Principle Investigator (PI) must be a faculty, staff, post-doc of a US-based educational institution or member of a commercial organization. Members of the project may be any researcher, including graduate students and visiting scholars. For detail, see XSEDE PI qualifications.
- What type of computer systems?
To determine the system that best match your hardware and software requirements, please see available resources.
- Which type of allocations (CPU time and disk storage allotments)?
There are 4 types of allocations available. A summary is given below. (For details, please consult the XSEDE allocation policy page.) Many may find it useful to start by experimenting with the existing SCV allocations on a few machines; then request a startup allocation on a specific system to do more in depth analyses which may eventually lead to a research allocation proposal that require strong justifications to win approval. However, if your computing resource requirement are fully understood, proceed directly with a startup or research application:
This is the simplest and quickest way to “sample” resources.
If you are not sure which resources are appropriate for your computing needs, this is the right place to start.
We, as an XSEDE member institution, have been given allocations by a few of the resource providers (institutions) across the country through XSEDE. We can add you as a member under this project, subject to approval by XSEDE.
PROS: no need to write a proposal; time to approval is several business days.
CONS: you can only run tiny jobs and the resource you are interested in may not be available.
