[Gems-users] partial rollback in transactional memory

[cge@xxxxxxxx]

Hi,
in microbenchmark/transactional/common/transaction.c in GEMS 2.1,
there is following codes:
//while (log_size > 0){
       while (xact_level >= lowest_conflict_level){      // PARTIAL ROLLBACK

If we choose to use while (log_size > 0), will nesting closed  
transactions have any
different effects on the performance compared to only using one-level  
transaction?
Thanks,
Ken
