HPC at Caltech

Do you need high performance computing resources for your research?  You've come to the right place!

IMSS DOES HPC

High performance computing has become an important element of research on campus.  Many groups have wanted to build clusters or run cloud-based ephemeral compute jobs, but do not know where to start. 

IMSS can help!  Whether containing just a few nodes or thousands of nodes,  IMSS can design, construct and maintain compute clusters both on campus and in the Amazon cloud.  We can implement high speed interconnects, parallel filesystems, or simple gigabit based clusters with NFS.
