Feature List

Zepto Compute Node Linux

Linux running on the compute nodes of Blue Gene/P.

Zepto-enhanced I/O node Linux

Our I/O node kernel and ramdisk are based on the standard V1R3M0 release, but feature a number of ZeptoOS-specific improvements

Run arbitrary processes on the compute nodes

Shell scripts, Java VM, unrestricted pthreads, etc.

Big Memory support

ZOID

ZeptoOS I/O Daemon performs job control and enables communication (remote file I/O, etc) between the compute nodes and the I/O nodes. ZOID can be easily extended through plug-ins to perform the forwarding of custom APIs.

Log into your I/O nodes

SSH daemon is enabled by default and is configured to allow the partition owner to log on the I/O nodes while the job is running.

Log into your compute nodes

Once logged on an I/O node, a user can open an interactive session to a compute node using telnet. This is made possible using the IP packet forwarding over the tree network, performed by ZOID.
