log entry reproduced below: -------------------------------------------------------------- Modified shape same tests to deal with the performance problem on Abe. Problem appears to have been caused by file system contention. In the chunked dataset case, reshaping the chunks so that only one process would touch each chunk and setting the alignment equal to the default Lustre block size more or less dealt with the problem. For contiguous datasets, the problem was a bit more difficult, as re-working the test to avoid contention would have been very time consuming. Instead, I added code to time one execution of each type of shape same test, and skip additional tests of that type if the duration of the test exceeded some threshold In all cases, I set up code to turn off the above fixes if express test is 0. Tested on Abe and commit tested. On the commit test, the configure test failed -- probably because I was h5committest from heiwa due to some ssh wierdness. In any case a manual reconfigure run on jam seemed to work fine. Also, in h5committest, I ran into some data conversion warnings. I didn't worry about them as the only code I changed was in testpar.
