There seem to be a few things going on here. for the test-all-cbq and test-all-red files, the data seems correct but the formatting is slightly off: there are commas for periods in some of the outputs. e.g. test-output-red/flows-combined.test > ==> flows_combined.test <== > TitleText: test_flows_combined > Device: Postscript > > "flow 1 > 84,8786 74,1902 > 48,3181 46,8733 vs. test-output-red/flows-combined (good output) > TitleText: test_flows_combined > Device: Postscript > > "flow 1 > 84.8786 74.1902 > 48.3181 46.8733 This may have something to do with the version of xgraph on the system. for the tcpLinux and tcpHighspeed tests, there are lines missing (either truncated, or interleaved in the test output) from the output when compared to the reference output. I don't know whether this is again a post-processing error or whether the simulation is not producing the same data. The test-output-xcp data is different: 0.12186 4200000 0.12186 4200000 0.12186 4200000 0.12228 8 0.12228 8 vs 0.12186 4200000 0.12186 4200000 0.12186 4200000 0.12228 8190000 0.12228 8190000 In summary, I would be suspicious of the use of the tcpLinux, tcpHighspeed, and xcp models on this platform. To debug this probably requires to step through the code at the points where the output diverge, using also a platform such as Linux that produces the reference output. I don't have ns-2 running on Mountain Lion yet but I'll check whether similar issues arise there. - Tom
