About IISER
The Indian Institute of Science Education and Research Pune is a premier indian institute dedicated to research and teaching in the basic sciences. Established in 2006. As a unique initiative in science education in India, IISER aims to be a Science University of the highest caliber devoted to both teaching and research in a totally integrated manner, with state-of-the-art research and high quality education, thus nurturing both curiosity and creativity.
Computing @ IISER
The computing facility and IT infrastructure at IISER Pune caters to allthe faculty, students and staff. The institute has a good number ofserver and workstation class computers for various system administration services. This is apart from the large number of PCsand workstations that serve the personal computing requirements
High Performance Cluster
IISER Pune has a 6 Tera FLOP high-performance computing cluster
primarily used by faculty and research students
This system has 512 cores spread over 64 nodes with 18 GB RAM per node and Infiniband interconnect
In addition, there 3 mini-clusters with number of coresranging from 60 to 100
HPC - details
64 nodes – each with quad core 2 * Intel(R) Xeon(R) CPU X5570 @ 2.93GHz 18 GB RAM
OS – RHEL 5.5
10 TB raw storage. RAID 5, Gluster, over NFS
CMS – ROCKS
Scheduler – PBS
Interconnect – IB DDR
HPC – challenges initially it was ext4 FS over NFS – installed glusterfs
number of users increased from <10 to >30
high memory requirement
GPU users – 2 such users
raw power requirement
data backup
Less manpower to manage infrastructure
Expansion PlansIISER Pune has plans to expand its HPC to 4000 cores. The plan is under discussion We are in the process for developing specs so as to satisfy computing needs and also address the problems that we face in current setup
Major design aspects under discussion are 4GB per core memory or 8GB Parallel file system Accelerators - GPU / Mic / both Interconnect speed System sizing – fat memory nodes, SMP node Aggregating current resources Opensource vs commercial software
Thank you!!
