once again, we would like to share some information with you through our newsletter:

1. Burst Buffer Testing: We have integrated a new storage server into the HPC cluster which provides a so-called burst buffer. Similarly to $TMPDIR, a job can request a directory with a certain size which is then available during the job for very fast I/O. The server with four NVMes can provide an I/O-bandwidth of up to 12GB/s, while a single compute node is limited to 6GB/s due to the FDR Infiniband. Please let us know if you have I/O-intensive applications that you would like to benchmark with the burst buffer. Details on the usage are explained in the HPC wiki.
2. Dates: Please take note following upcoming events
   • Introduction to HPC course: September 14^th to 16^th, 10 am – 17 pm (online)
   • Meeting of the HPC user representatives: September, 18th at 10 am (online)
   • Deadline for HLRN proposals: October, 28th
3. Software News: The following modules are now available on hpc-env/8.3:
   • Lumerical/2020-R2.1-2408
   • Mesa/20.0.2-GCCcore-8.3.0
   • X11/20200222-GCCcore-8.3.0

The list above might not be complete, you can always search for software with the command “module spider <softwarename>”.

The next newsletter is planned for October.
