I have an application which encounters a read error on one of four processes during a call to ``MPI_File_read_at_all``. This error causes the rank to return from a loop before...
While running PnetCDF tests on a file system that requires stricter adherence to the MPI-I/O consistency semantics (UnifyFS), I found that several test cases involving fill operations were not calling...
With the collective write calls in MPI I/O, the MPI library may rearrange data among processes to write to the underlying file more efficiently, as is done in ROMIO's collective...
The ``test/nonblocking/mcoll_perf.c`` test detects incorrect data when comparing two files that were written two different ways which should have identical content. ``` cd test/nonblocking srun -n2 ./mcoll_perf /unifyfs/testfile.nc P0: diff...
The PnetCDF ``test/largefile/large_coalesce`` test returns the value of 0 for bytes that should have a non-zero value. ``` *** TESTING C large_coalesce for skip filetype buftype coalesce ------ 0 (at...
In PnetCDF, the ``nc_test`` has a number of quick running tests that each create a scratch file, execute I/O operations on that file, and then delete the scratch file. The...
When creating a file in PnetCDF, one can use the ``NC_CLOBBER`` flag, which indicates that any existing file should first be unlinked or truncated to 0 bytes. For regular files,...
While running a particular margo test https://github.com/Parallel-NetCDF/PnetCDF/blob/master/test/largefile/high_dim_var.c with 4 ranks on 2 nodes, a read from rank 2 invokes a failure on the server, which generates the following logs: ```...
Currently, SCR records the resource manager that was selected at configure time in ``config.py``, which is what ``AutoResourceManager`` defaults to. To enable a single SCR install to support multiple systems...
Here is the old issue opened with Flux about tolerating node failures. https://github.com/flux-framework/flux-core/issues/4417 We want to be sure that scalable restart is supported in a Flux allocation in which a...
