SUMMARY:The Taming of the Wolf - How to use the Ookami Cray Apollo 80 syste
 m and Fujitsu A64FX processors
DESCRIPTION:The team running the Ookami HPE/Cray Apollo 80 system at Stony 
 Brook University and from the University at Buffalo is holding a 6 hour wo
 rkshop at the PEARC’23 conference. The workshop will focus on the charac
 teristics of the Ookami testbed and the specific architecture of the Fujit
 su A64FX FX700 processor.\n\nSince October 2022, Ookami has also been an o
 fficial ACCESS resource provider, as well as a Stony Brook resource. The O
 okami scientific-computing and user-support team employs on a multi-modal 
 outreach approach. This includes a closely-monitored Slack channel, twice-
 weekly office hours in which anyone can address any related issues, a tick
 eting system (both via Stony Brook and ACCESS), and by directly funding gr
 aduate students and working with them on science codes used by their resea
 rch groups.\n\nOur experience has shown that many users need a substantial
  amount of support, mainly because of the novel architecture of the A64FX 
 processor, and unfamiliar toolchains. Many recipes that you might expect t
 o work on standard x86 systems do not produce optimal results on this arch
 itecture, and achieving good performance often requires a more sophisticat
 ed and nuanced methodology. \n\nThe focus of this workshop is thus to ena
 ble people to get a closer look at this interesting architecture, understa
 nd the challenges and opportunities it presents, become familiar with the 
 software toolchains and performance analysis tools, and through hands-on a
 ccess with experts in the room find ways to tackle and take advantage of t
 hem.
