Garbage collectors and other software can utilize high performance lock-free multithreaded software. A uniform lock-free update to a set of variables involves updating the values Z, release barriers and acquire barriers (which enforce an ordering of code execution), and atomicity resulting from alignment of the variables. The transfer is done through a value placement step and a value retrieval step. The value placement replaces the un-updated values in Varl with Z, executes a release barrier, replaces the un-updated values of other variables with the updated values, executes another release barrier, and replaces Z with the Varl updated values. The value retrieval reads from Varl into DestVarlA, executes an acquire barrier, reads from the other variables into the corresponding destination variables, executes another acquire barrier, reads from Varl into DestVarlB, and repeats if DestVarlA is Z or if DestVarlA and DestVarlB are not equal. This solution updates the values as a unit without locking.
