<p style="font-size:14px;line-height:26px;margin:16px 0;font-weight:700;color:#0b4c91">Description</p>
<p style="font-size:14px;line-height:22px;margin:16px 0;color:#3c4043">UCR HPCC will be performing a maintenance shutdown at the above specified time. A Slurm reservation has been put in place to prevent jobs from running during the scheduled maintenance. This shutdown is necessary for routine software updates, and certain configuration changes that can not be done while the cluster is active.</p>
<p style="font-size:14px;line-height:26px;margin:16px 0;font-weight:700;color:#0b4c91">Benefits</p>
<p style="font-size:14px;line-height:22px;margin:16px 0;color:#3c4043">Regular cluster maintenance keeps our systems performant, secure, and reliable.</p>
<p style="font-size:14px;line-height:26px;margin:16px 0;font-weight:700;color:#0b4c91">Schedule: 8AM July 28 to afternoon of July 29</p>
<p style="font-size:14px;line-height:22px;margin:16px 0;color:#3c4043">Slurm will hold any jobs that would otherwise start or extend into the above specified time. Users will also be logged off so maintenance tasks can be done. Services will be restored gradually, with full operations expected by the end of the maintenance window.</p>
<p style="font-size:14px;line-height:26px;margin:16px 0;font-weight:700;color:#0b4c91">Services Impacted</p>
<p style="font-size:14px;line-height:22px;margin:16px 0;color:#3c4043">Most services hosted by HPCC will be down during this period. This includes, but is not limited to:</p>
<ul style="font-size:14px;line-height:22px;margin:16px 0;color:#3c4043">
<li style="font-size:14px;line-height:22px;margin:16px 0;color:#3c4043">Cluster access (SSH, Slurm, data access), including HTTP access to user data.</li>
<li style="font-size:14px;line-height:22px;margin:16px 0;color:#3c4043">All services provided by OnDemand: RStudio/Posit, MATLAB, Jupyter, etc.</li>
</ul>
<p style="font-size:14px;line-height:22px;margin:16px 0;color:#3c4043">Normal email support (<a href="mailto:support@hpcc.ucr.edu" target="_blank">support@hpcc.ucr.edu</a>) will continue to operate. However, HPCC's Slack workspace (<a href="https://ucr-hpcc.slack.com" target="_blank">https://ucr-hpcc.slack.com</a>) will be the main means of group communication with users during maintenance events. We strongly encourage users to become familiar with our Slack workspace ahead of the shutdown.</p>
<p style="font-size:14px;line-height:22px;margin:16px 0;color:#3c4043">We will provide more information and additional reminders as the shutdown gets closer.</p>
