MANAGEMENT OF MIGRATING THREADS WITHIN A COMPUTING ENVIRONMENT TO TRANSFORM MULTIPLE THREADING MODE PROCESSORS TO SINGLE THREAD MODE PROCESSORS

Threads of a computing environment are managed to improve system performance. Threads are migrated between processors to take advantage of single thread processing mode, when possible. As an example, inactive threads are migrated from one or more processors, potentially freeing-up one or more processors to execute an active thread. Active threads are migrated from one processor to another to transform multiple threading mode processors to single thread mode processors.
