Berkeley Lab Checkpoint Restart Saves Big Problems

February 9, 2009

A combustion researcher may run hundreds of hours of simulations on a supercomputer in search of the most efficient fuel-air mixture for a flame. But if the system crashes, then all the data from the run might be lost and the researchers forced to start over The new version Berkeley Lab Checkpoint Restart (BCLR) software, released in January 2009, could mean that scientists running extensive calculations will be able to recover from such a crash – if they are running on a Linux cluster. This… Read More »
