Yet another precompilation-on-HPC issue

Davide_DelVento · November 2, 2023, 9:52pm

I administer an HPC cluster and I’ve installed Julia (using spack as a package manager) globally. Spack compiled julia in /tmp/aaa/spack-stage/spack-stage-julia-1.9.2-yux5s54oyok6xiifl5xwqeqjljazifjg/spack-src/ and then installed it on another location. Somewhat Julia remembers that “compilation” location and at least in certain circumstances it fails to install new packages, with an error such as IOError: stat("/tmp/aaa/spack-stage/spack-stage-julia-1.9.2-yux5s54oyok6xiifl5xwqeqjljazifjg/spack-src/usr/share/julia/stdlib/v1.9/Zlib_jll/src/Zlib_jll.jl"): permission denied (EACCES). The “certain circumstances” are related to the fact that I may be compiling other software and the directory /tmp/aaa/spack-stage/ exists and is owned by a different user. I am not sure if there’s also a race condition between multiple users attempting to both install at the same time: if Julia does create the directory, it disappears so fast that I have not been able to see it.

Is there a way to tell Julia “use /tmp/$USER/” to workaround this problem?

I tried DEPOT_PATH and BUILD_STDLIB_PATH and even PKG_DEVDIR but I either used them incorrectly or they don’t do what I want. DEPOT_PATH especially appears to break everything else in Julia… Some old bugs mention Base.LOAD_CACHE_PATH but that does not exist anymore and the related Base.LOADING_CACHE and Base.LOAD_PATH do not seem to do what I want.

Suggestions?

Set TMPDIR:

% TMPDIR="/tmp/${USER}" julia -E 'tempdir()'
"/tmp/mose"

See tempdir

If you are running with a batch system then $TMPDIR should be set by the batch system and this area created and torn down at the end of the job. You can customise the location of $TMPDIR in the batch system config files

Davide_DelVento · November 3, 2023, 12:49pm

Thanks both for the suggestion, but unfortunately that’s not it.

Setting TMPDIR as indicated makes it visible by julia as in the example @giordano showed. Despite that running things like using Revise still attempts to precompile it in that not appropriate location and fails with IOError: stat("/tmp/aaa/spack-stage/spack-stage-julia-1.9.2-yux5s54oyok6xiifl5xwqeqjljazifjg/spack-src/usr/share/julia/stdlib/v1.9/LibSSH2_jll/src/LibSSH2_jll.jl"): permission denied (EACCES)

Just in case I tried deleting my ~/.julia directory and of course in that way it says

ERROR: ArgumentError: Package Revise not found in current path.
- Run `import Pkg; Pkg.add("Revise")` to install the Revise package.

Redoing the import Pkg; Pkg.add("Revise") makes it fail again in the same way, so it must be using something of higher priority for setting this location.

Any idea about what that may be?

Just to show that I did not fat-finger this, or if there is any additional clue that can help debug the issue, here is a full capture

Note that sw is not an user of this machine and that /home/sw/ is only a location shared for everybody to read (as /opt is on other machines).

Note also (not shown) that the directory /tmp/davide exists and is writable by current user.

Thanks a lot to anybody who will provide additional insight!
