| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Checked in fix for failure in shape same tests that appeared after Quincy's recent massage of the test code. The problem was a race condition created when Quincey re-worked the code selecting either collective or independant I/O. Previously, when independant I/O was selected in the test, I had used H5Pset_dxpl_mpio() and H5Pset_dxpl_mpio_collective_opt() to select collective semantics with independant I/O going on under the hood. Quincey modified this to call H5Pset_dxpl_mpio() when collective I/O was selected, and do nothing in the independant I/O case. As a result, processes were able to race ahead and modify the initial values of the data set before some processes had verified that the initialization was correct. Solved the problem by adding barriers, and making all barriers dependant on independant I/O being selected. Tested parallel on amani and phoenix. h5committested. Note that parallel on amani and h5committest on heiwa failed several times before I got a clean pass without code changes. The failures on amani seemed to be time outs caused by contention for the machine -- worryingly, they occurred in the shape same tests. However, given subsequent passes and passes on jam and phoenix, I am going ahead with the commit. The failure on heiwa was in the fheap test. I don't see how this can be related to changes in testpar, and in any case, it went away on the second try.

| | | | | | | | | Correct tests to use native datatypes consistently, and also to use "normal" methods for performing collective I/O. Also, minor cleanups for zeroing out buffers, etc. Tested on: AIX/64 6.? (bp) w/parallel

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | Clean up warnings, etc. Tested on: Linux/64 2.6 (abe) w/parallel (to specific to need h5committest)
* [svn-r19168] Description:Quincey Koziol2010-08-041-2/+2
| | | | | | | Clean up some compiler warnings. Tested on: Linux 2.6/64 (abe) w/parallel
* [svn-r19130] Description:Quincey Koziol2010-07-261-2/+2
| | | | | | | Correct another inadvertant use of macro instead of versioned API name. Tested on: Eyeballed only, too minor to require h5committest

Bring "shape same" changes from LBL branch to trunk. These changes allow shapes that are the same, but projected into dataspaces with different ranks to be detected correctly, and also contains code to project a dataspace into greater/lesser number of dimensions, so the I/O can proceed in a faster way. These changes also contain several bug fixes and _lots_ of code cleanups to the MPI datatype creation code. Many other misc. code cleanup are included as well...
