From ccb1a917b6e68bc51a6a4e3d6783edfa056b01bf Mon Sep 17 00:00:00 2001 From: Dana Robinson <43805+derobins@users.noreply.github.com> Date: Mon, 16 Oct 2023 10:19:15 -0700 Subject: Fix printf warnings in t_mpi (#3679) * Fix printf warnings in t_mpi The type of MPI_Offset varies with implementation. In MPICH, it's long, which raises warnings when we attempt to use long long format specifiers. Casting to long long fixes the warnings. --- testpar/t_mpi.c | 9 ++++++--- 1 file changed, 6 insertions(+), 3 deletions(-) diff --git a/testpar/t_mpi.c b/testpar/t_mpi.c index 70a76ec..eff39d0 100644 --- a/testpar/t_mpi.c +++ b/testpar/t_mpi.c @@ -306,12 +306,14 @@ test_mpio_gb_file(char *filename) for (i = ntimes - 2; i <= ntimes; i++) { mpi_off = (i * mpi_size + mpi_rank) * (MPI_Offset)MB; if (VERBOSE_MED) - fprintf(stdout, "proc %d: write to mpi_off=%016llx, %lld\n", mpi_rank, mpi_off, mpi_off); + fprintf(stdout, "proc %d: write to mpi_off=%016llx, %lld\n", mpi_rank, (long long)mpi_off, + (long long)mpi_off); /* set data to some trivial pattern for easy verification */ for (j = 0; j < MB; j++) *(buf + j) = (int8_t)(i * mpi_size + mpi_rank); if (VERBOSE_MED) - fprintf(stdout, "proc %d: writing %d bytes at offset %lld\n", mpi_rank, MB, mpi_off); + fprintf(stdout, "proc %d: writing %d bytes at offset %lld\n", mpi_rank, MB, + (long long)mpi_off); mrc = MPI_File_write_at(fh, mpi_off, buf, MB, MPI_BYTE, &mpi_stat); INFO((mrc == MPI_SUCCESS), "GB size file write"); if (mrc != MPI_SUCCESS) @@ -345,7 +347,8 @@ test_mpio_gb_file(char *filename) for (i = ntimes - 2; i <= ntimes; i++) { mpi_off = (i * mpi_size + (mpi_size - mpi_rank - 1)) * (MPI_Offset)MB; if (VERBOSE_MED) - fprintf(stdout, "proc %d: read from mpi_off=%016llx, %lld\n", mpi_rank, mpi_off, mpi_off); + fprintf(stdout, "proc %d: read from mpi_off=%016llx, %lld\n", mpi_rank, + (long long)mpi_off, (long long)mpi_off); mrc = MPI_File_read_at(fh, mpi_off, buf, MB, MPI_BYTE, &mpi_stat); INFO((mrc == MPI_SUCCESS), "GB size file read"); expected = (int8_t)(i * mpi_size + (mpi_size - mpi_rank - 1)); -- cgit v0.12
