I did the Cluster Challenge again this year. Last year was fun, but this year was better – we won! Here’s the story:
We started Saturday morning in Bloomington. The travel went pretty

Yes, it is as cryptic as it sounds . I finally (after a couple of months) finished to merge Christian’s MPI_Bcast() patch with my LibNBC patch to enable the usage of non-blocking collectives in HPL.
