Hello Bill,
Recently, when we ran IOR (version 2.9.0) in the MPIIO mode to test the
performance of Lustre, we encountered the following error:
** error **
ERROR in aiori-MPIIO.c (line 303): cannot access explicit, noncollective.
MPI Invalid argument
** exiting **
After looking into the IOR codes, we found that the offset parameter
passed to MPI_File_read_at() api was negative, and this was due to the
incorrect data type of tmpOffset variable in WriteOrRead() function in
IOR.c. It's declared as "int", and we think it should be "IOR_offset_t".
Could you please take a look at this issue?
BTW: this issue also exists in other 2.9-series IORs.
Thanks.
