Name the cluster!!
- Win a free hot-apple pie
(Scyld) Development Environment
- Paul's VM plus physical nodes
- Intel vs. AMD software builds?
Software
Intel Compiler - do we need it?
Apps to install on xcluster:
- MPI, multi-core, big-memroy, serial?
- Popular apps (regardless of type; how to determine?):
- time stamps on app dirs??
- access time of executable??
New queueing system:
- how/what to configure (e.g. fairshare, queues, "complexes")
Use module or not?
Scyld
- Location of /usr/local/apps, libraries, and languages e.g., Perl
- A bunch more stuff needed here
Cloud Manager
Lab Group Registration:
- Lab VM login nodes
User Accounts:
- New request from PI's
- CAS/LDAP authentication?
- affiliate accounts?
Storage
- HPC IceBreaker (3 x 48TB chains)
- one chain for /home, /db, and /usr/local?
- two chains for scratch?
- Archive IceBreaker (2 x 320TB chains)
- /oflow and /home, /usr/local backups
- Lustre ClusterStor
- scratch for zcluster via 10GBE
- scratch for xcluster via 10GBE, maybe IB later
PB notes
- note: don't want perlwrapper this time
- research: will scratch icebreakers run over Ethernet also, or only IB, for storage?
- research: try out POD
- research: what is difference between building on Intel vs AMD?
- decision: which compiler to use by default? I think we think gcc.
- research/decision: will we do "qlogin"? an interactive queue? what kind of enforceable resource limits?
- http://www.nics.tennessee.edu/~troy/pbstools/ for a qlogin
- dunno about resource limits yet
- decision: paths for /usr/local apps?
- research: can scyldev see zhead license server?
- will know after testing the now-installed PGI
- decision: RPMs vs not for /usr/local
Documentation
- cloud, login nodes, etc.
- queuing system
