Dear Franklin users, Franklin quad core upgrade phase 3 is tentatively scheduled to start on Sept 10. Franklin will be first in full machine production with 8 columns of quad core nodes and 9 columns of dual core nodes first (phase 3a, total of 28,496 compute cores). Then 7 columns of dual core nodes will be moved one week later to the test environment for quad core upgrade and Franklin will be in production with 8 columns of quad core nodes and 2 columns of dual core nodes (phase 3b, total of 20,432 compute cores). Two important messages regarding phase 3 upgrade are: 1) Charging for computing on the quad core nodes will start from phase 3. However, the charging rate will be the same as for the dual core nodes. i.e., wall clock hours x num_nodes_used x 2 cores/node (instead of 4 cores/node here) x 6.5 machine charge factor x queue priority. And there will be no new allocations from DOE for the allocation year AY08. 2) The default user environment will be set to quad core environment. This means that the default built executable will be targeted to run on the quad core nodes. Please refer to the detailed upgrade schedule information along with the user environment changes and usage guide for phase 3 at: https://www.nersc.gov/nusers/systems/franklin/quadcore_upgrade.php#phase3 Best Regards, Helen He NERSC User Services _______________________________________________ franklin-users mailing list franklin-users_at_nersc_dot_gov
