about ogc
our history


OGC is the primary maintainer of the LDMS open source system monitoring stack providing development, customization and support services to the largest HPC systems in the world.


HPE/Cray selects LDMS to be the preferred monitoring infrastructure for HPC systems.



OGC invents Maestro, the parallel, resilient, load balancing distributed configuration manager.

LDMS is deployed on the Cori supercomputer at Lawrence Berkeley labs.


OGC wins the prestigious Department of Energy R&D 100 award in conjunction with Sandia National Labs for the invention of the LDMS protocol, SOS and associated monitoring infrastructure software.


OGC creates the Prism data analysis subsystem in conjunction with Grafana to provide a powerful visualization infrastructure for LDMS data.

LDMS is deployed on the Trinity Supercomputer at Los Alamos National Laboratory.


OGC invents the Axis Scalable Object Store that provides unparalleled insertion rates of indexed data on federated storage architectures.


OGC in conjunction with HGST develops the Hornet Ethernet/RDMA attached drive.

 LDMS is deployed on the NERSC Blue Waters 28,000 node Supercomputer at UIUC.


OGC invents the LDMS protocol to enable the lightweight monitoring of HPC systems using the unique capabilities of RDMA transports.


OGC designs and implements the RDMA transport for the NFS filesystem. This allows NFS to run over the Infiniband and iWARP transports.


OGC designs and develops the transport independent connection management services for the OFED software stack allowing applications to be written to use both the Infiniband, and iWARP RDMA transports without modification.


OGC is founded in Austin, Texas to provide Open Source Development Services to the Linux community specializing in kernel, device driver, networking and filesystem development.
