Hi Mingyu and everyone,
<div class=""><br class="">
</div>
<div class="">It looks that the issues with the removed symlink were resolved, and everything should work again. For future deployments I will make sure to integrate with the module system to (hopefully) avoid this from happening in the future.</div>
<div class=""><br class="">

<div class="">Best,</div>

<div class="">Hi Mingyu, et al,<br class="">
<br class="">
It looks like there were some backwards-incompatible changes to<br class="">
/apps/singularity/ on Friday. I think the relevant software is still<br class="">
there, but symlinks need to be made to allow existing code to work<br class="">
with the new configuration.<br class="">
<br class="">
I'm CC'ing the group and Sylvester so we all have a heads-up. I emailed<br class="">
the IT person in charge and asked that symlinks be restored for now<br class="">
(along with a reminder that notice of regressions should be given via<br class="">
scicomp-briefs in the future). I expect that symlinks will be restored<br class="">
quickly. I recommend that folks just wait until tomorrow rather than<br class="">
make local fixes.<br class="">
<br class="">
FWIW, it looks like the new standard path will be<br class="">
/apps/singularity/3.5.2<br class="">
instead of <br class="">
/apps/singularity/singularity-3.5.2<br class="">
It looks like IT is also moving towards using the 'module' system. That<br class="">
is a good thing in the long run.<br class="">
<br class="">
Sylvester may want to make the change to invoke the relevant IT module<br class="">
when he can, or wait a bit and see how this all settles out.<br class="">
<br class="">
REMINDER: I'll also take this opportunity to remind everyone of the<br class="">
/apps and /site planned outage scheduled that starts Tuesday<br class="">
afternoon. This was posted to the scicomp-briefs list last week.<br class="">
More details are here:<br class="">

Hopefully there is nothing in particular you need to do, but do be<br class="">
aware that may be a significant service disruption that evening.<br class="">
<br class="">
Note that I will be disabling the /site and /apps mountpoints on<br class="">
the Hall C Cluster machines Monday night and restoring them on Wed<br class="">
morning. (Hopefully no one is analyzing on the Hall C machines<br class="">
anymore though.)<br class="">

I encountered a strange problem with hallc_replay. Up to yestoday<br class="">
(11/14/2020), both hallc replay and root works fine on JLab<br class="">
ifarm. However, today after I load the PolHe3 software environment:<br class="">
$ source /group/c-polhe3/software/setup.sh<br class="">
when I do:<br class="">
$ root -l<br class="">
I get this message:<br class="">
$ /group/c-polhe3/software/opt/hallac_container_1.8/bin/root: line 19:<br class="">
/apps/singularity/singularity-3.5.2/bin/singularity: No such file or<br class="">
directory<br class="">
I am not sure what cause the missing file to prevent root run properly<br class="">
after setting up the PolHe3 software environment, could you take a look?<br class="">
Attached screen shot has the details of this problem.<br class="">

work for everyone. Do let me know if you hit problems or have<br class="">
questions.<br class="">

There are many ways to work with git. The basic idea here is basically<br class="">
the same as the github 'fork and pull request' workflow. That is<br class="">
outlined on the link above. You can find more detailed descriptions at<br class="">
the 'Git Howto' page at the bottom of the above link, and/or skim<br class="">
this quick article.<br class="">

(Note that we are using the ANL GitLab server and /not/ GitHub for our<br class="">
work. Don't worry though, the process is basically the same.)<br class="">
