If your server/repository does not support merge-tracking then this is the only way to merge a branch back to trunk. It arranges k ordered lists of length n each into one ordered lists in T(k)+[log/sub 2/k] [log/sub 2/m] [log/sub 2/m] steps, where T(k) is the number of steps needed to sort k keys in order; and k and m are any integers no longer restricted to 2. •The K-Way Merging Algorithm just described works well if k < 8. In the first stage, PMCC first divides the input dataset into multiple blocks so that each block can fit into the shared L2 cache, and then employs multiple cores to perform parallel cache sorting to generate sorted blocks. They may not be reproduced or distributed in any form or by any means, or stored in a data base or retrieval system,. As far as benefits go, vacation days are great and nobody objects to free parking, but a 401(k) plan could. The results of the MERGE verb are predictable only when the records in the input files are ordered as described in the KEY clause associated with the MERGE statement. Merge sort first divides the array into equal halves and then combines them in a sorted manner.
