Howdy!
I was writing some netCDF tests for parallel I/O, trying to write an array of strings with parallel I/O.
But I get this error:
HDF5-DIAG: Error detected in HDF5 (1.10.1) MPI-process 2:
#000: H5Dio.c line 269 in H5Dwrite(): can’t prepare for writing data
major: Dataset
minor: Write failed
#001: H5Dio.c line 345 in H5D__pre_write(): can’t write data
major: Dataset
minor: Write failed
#002: H5Dio.c line 656 in H5D__write(): Parallel IO does not support writing VL datatypes yet
major: Dataset
minor: Feature is unsupported
This suprised me. Will VLEN ever be supported with parallel I/O?
Is this just a restriction on writing? Can I read VLENs with parallel I/O?
Thanks!
