Dear Alejandro, Could you estimate how much more time you now and the end of March? In March the LCRC Allocations Committee meets to make decisions about the time allocations for Q3 and Q4 (April-Sept.). So the immediate decision is between now and March 31st, and the rest of your request can be added to your original request for Q3 and Q4.

Hello,

A change in allocation has been requested:

Requester: albezanilla (Alejandro Lopez Bezanilla) Project: Irridates Title: Metal-insulator phase transitions in irridates Description: We will use MPI Fortran codes developed at Coulumbia University at NYC. Based on previous cluster DMFT calculations for a model tight binding Hamiltonian we estimate the CPU hours for a submitted job as 10k: 12 nodes * 16 cores per node (Blues) running for 48 hours. The work will be divided in multiple sets containing external parameters. Considering the limited resources, we will target parameters to solve instead of surveying entire phase diagram. Previous tests using thousands of cores simultaneously indicate that a better performance is achieved running jobs on hundreds of cores. The project is expected to have three members at most. Current: undetermined amount Justification:

Requested: 350000

A specific reason has been given: Our DMFT calculations uses configuration-interaction-based exact diagonalization solvers which are very time consuming

This needs to be approved and the final allocation amount decided upon.

Thank You, The LCRC Accounts System _______________________________________________ allocations-admins mailing list [email protected] https://lists.lcrc.anl.gov/mailman/listinfo/allocations-admins
