generic easyblock for Cray toolchains #766

boegel · 2015-12-11T11:45:33Z

(requires ~~easybuilders/easybuild-framework#1506~~)

required for stable Cray support (cfr. easybuilders/easybuild-framework#1390)

boegel · 2015-12-11T11:48:01Z

Example easyconfig:

easyblock = 'CrayToolchain'

name = 'CrayGNU'
version = 'test'

homepage = '(none)'
description = """Toolchain using Cray compiler wrapper, using PrgEnv-gnu module."""

toolchain = {'name': 'dummy', 'version': 'dummy'}

dependencies = [
    ('PrgEnv-gnu/5.2.40', EXTERNAL_MODULE),
    ('gcc/4.8.2', EXTERNAL_MODULE),
    ('cray-mpich/7.2.2', EXTERNAL_MODULE),
    ('cray-libsci/13.0.4', EXTERNAL_MODULE),
    ('fftw/3.3.4.2', EXTERNAL_MODULE),
]

moduleclass = 'toolchain'

resulting module file:

#%Module
proc ModulesHelp { } {
    puts stderr { Toolchain using Cray compiler wrapper, using PrgEnv-gnu module. - Homepage: (none)
    }
}

module-whatis {Toolchain using Cray compiler wrapper, using PrgEnv-gnu module. - Homepage: (none)}

add \n between comment and txt?

that's already there implicitly (since I'm not stripping the return value of .comment()), it would result in a double newline in the generated module file

Looks better now, why no swap instead of the unload/load sequence?

boegel · 2015-12-14T08:29:13Z

@pforai: a swap fails if the module being swapped out is not loaded; an unload is always 'safe': it doesn't fail if the specified module is not loaded, and is a no-op when the module in which it is included is unloaded (so the is-loaded guards are useless)

When --recursive-module-unload is enabled, we get a module like this:

boegel · 2015-12-14T13:23:40Z

The problem seems to be that the modules tool does not respect the unload/load order as specified in the module file, see for example https://gist.github.com/boegel/7f724f7f69045f834392 .

The del os.environ[..] statements are all done at the end...

@rtmclay: is there a way to fix this?

rtmclay · 2015-12-14T14:20:56Z

I don't think it is safe to load the PrgEnv-gnu/5.2.40 and then unload gcc and reload it. But to really tell what is going on, you'll need to find the exact place where in the CrayGnu modulefile it is failing. I think it will be inside one of the Cray modules and not in the one you are showing above.

boegel · 2015-12-14T14:42:33Z

@rtmclay: well, it's not failing in the sense that loading this module fails, but we're getting an environment that isn't what we think it should be.

How would you pinpoint the exact problem here? Also, why do things work when I have the is-loaded guard in place around the unload/load statements? I'm not sure I understand when why it does work in that case...

I'm seeing the same problem when using module swap rather than an unload follow by load.

gppezzi · 2015-12-15T21:31:11Z

@rtmclay gave a good hint: unloading PrgEnv-gnu and then reloading it seems to be the cause of this problem.

Strangely enough it works for the first time you load CrayGNU but it ruins your environment if you load it twice (and that' s probably what EB is internally doing in this case?).

I tried this workaround in order to avoid unloading it and by far this seems to work:

if { ![ is-loaded PrgEnv-gnu ] } {
   module load PrgEnv-gnu/5.2.82
} else {
   module swap PrgEnv-gnu PrgEnv-gnu/5.2.82
}

fix for PrgEnv-* unloading problem

lgtm

HPL basic tests passed on both Piz Daint and Piz Dora (see #2222).

I did some basic testing and I the environment problems caused by reloading PrgEnv-* seem to be fixed with this version.

I've also successfully used this easyblock to compile Python, including numpy on top of libsci.

Thanks a lot @boegel for all the support!!

boegel · 2016-01-21T18:57:34Z

@gppezzi: thanks for the feedback, I see no reason to hold this back any further

It would be great if @pforai is able to test this on another (non-CSCS) Cray system indeed, with the easyconfigs available in easybuilders/easybuild-easyconfigs#2222, but he can also do that with EasyBuild v2.6.0 very soon. ;-)

Easyblocks unit test suite PASSed (see https://jenkins1.ugent.be/job/easybuild-easyblocks-pr-builder/1618/console for more details).

This pull request is now ready for review/testing.

Please try and find someone who can tackle this; contact @boegel if you're not sure what to do.

generic easyblock for Cray toolchains

gppezzi · 2016-02-24T09:27:04Z

After hitting a couple of nasty bugs and after discussion with Cray, @pforai and @boegel, here's the new proposal for the module file.
Main changes are:

Stop pinning PrgEnv-* version: since cray always recommends to use the latest and swapping it inside module files is causing some weird side effects on the environment
Remove craype as dependency: this module should be backwards compatible and is version pinned on the PrgEnv
Remove fftw as dependency: in order to avoid changing the default Cray PrgEnv and to avoid bugs when compiling python with the fftw module loaded.
