The difference in Vaildation results for different macOS (Darwin) revisions persists for SCC and is not intermittent. It does not occur for MCM. The dividing OS revision remains 22.4.0.
----------------------------------------If a workunit has 2 completed replications with OS rev <22.4.0 or 2 completed replications with OS rev >=22.4.0 then the workunit will be valid. If a workunit has 1 completed replication with OS rev <22.4.0 and 1 completed replication with OS rev >=22.4.0 then another replication will be generated for the workunit. This implies that the 2 different OS rev groups are producing different result files. This does not occur for MCM or other projects, only SCC. If the additional replication completes and is OS rev <22.4.0 then the replications with OS rev <22.4.0 will be VALID and the replication with OS rev >=22.4.0 will be INVALID If the additional replication completes and is OS rev >=22.4.0 then the replications with OS rev >=22.4.0 will be VALID and the replication with OS rev <22.4.0 will be INVALID This happens every time it occurs. The majority revision group prevails. TigerLily: Please inform the SCC team of the issue. Thanks. (edited 9/1/2023 to correct the boundary OS rev from 22.5.0 to 22.4.0) [Edit 1 times, last edit by Taurus Oldbull at Sep 1, 2023 1:45:40 PM] |

Thank you so much Taurus Oldbull for continuing to bring this issue up. I think the researchers really should know, and acknowledge they know about this issue.
