ASCR Leadership Computing Challenge (ALCC) Projects at NERSC
The mission of the ASCR Leadership Computing Challenge (ALCC) is to provide an allocation program for projects of interest to the Department of Energy (DOE) with an emphasis on high-risk, high-payoff simulations in areas directly related to the DOE mission and for broadening the community of researchers capable of using leadership computing resources.
Open to scientists from the research community in industry, academia, and national laboratories, the ALCC program allocates time on computational resources at ASCR’s supercomputing facilities. ASCR supercomputing facilities include NERSC at Lawrence Berkeley National Laboratory and the Leadership Computing Facilities at Argonne and Oak Ridge National Laboratories. These resources represent some of the world’s fastest and most powerful supercomputers.
Allocations of computer time are awarded through a competitive process by the DOE Office of Advanced Scientific Computing Research. For more information about the program and instructions on how to apply see the DOE ALCC page.
The ALCC year runs from July to June. This is shifted six months from the NERSC allocation cycle, so the full ALCC award for each project is allocated 50% in one NERSC allocation year and 50 percent in the next. Any, or all, of this time can be shifted from one year to the next upon request. Unused time from July through December is automatically transferred into the following year, however ALCC awarded time does not carry over past June 30.
ALCC allocations are given in node-hours. These are converted to NERSC hours. A description of how jobs are charged can be found here: How Usage is Charged
