benchmarks won't complete as file not found.

[christophermaynard]

Benchmarks won't as file not found. The benchmarks start but each one exits with file not found, but it doesn't tell me which file. I used the configuration.json file which comes with the 1.1 release. For write, perhaps I need to provide the file? but what and where? For the write, well surely it should be writing the file!

This is the error I am facing during installation:

 ls

Thanks for any help. Software Environment

• version of h5bench: [e.g. 1.0]
• installed h5bench using: [spack, from source]
• operating system: [name and version]
• machine: [Are you running on a supercomputer or public cluster?]
• version of HDF5: [e.g. 1.12.0]
• version of VOL-ASYNC: [e.g. 1.13.1]
• name and version of MPI: [e.g. OpenMPI 4.1.1]

Additional Information

Add any other information about the problem here.

I had the same problem. The error message says no file called h5bench_write. "h5bench_write" is located at the same place as the file "h5bench" (i.e. the build directory). I fixed this issue by adding the build directory to PATH.

[jeanbez]

@christophermaynard and @yzanhua we fixed that in the main branch, could you confirm you are not still facing this issue?

[yzanhua]

@jeanbez I am still facing this issue if I call h5bench from another directory different from the build directory. For example the following does not work:

$ mkdir ~/test
$ cd ~/test
$ /path-to-h5bench-build-directory/h5bench --debug configuration.json

I see in the "h5bench" python script that there is a "PREFIX" appended before "H5BENCH_PATTERNS_WRITE". But it seems no one will modify "PREFIX" .

[jeanbez]

@yzanhua so the directory where you installed h5bench is not in the global path, correct? If that is the case, the script with not find the executables if you are not launching it from the directory where it was built. I'll update the documentation to clarify that.

[yzanhua]

@jeanbez Yes. Adding the build directory to the global path helps me solve the issue. Thank you for the clarification.
