Introduction

The Data Transfer Node (DTN) at Rice (Rice CRC Data Transfer Node) at Rice facilitates the movement of data into and out of the "/work" shared filesystem available on for DAVinCI , NOTS, and Blue Biou and scratch filesystems available on and NOTS. Scratch filesystem available for DAVinCI "/dascratch", Blue Biou "/gpfs-biou". DTN2

DTN2 (Rice CRC Data Transfer Node 2) facilitates the movement of data into and out of PowerOmics for "/poscratch".

Rice University CRC DTN HA facilitates the movement of data into and out of Blue Gene/Q the "/bgqscratchscratch" and PowerOmics and "/poscratchprojects" shared filesystems available for NOTS. Both DTN and DTN2 It also provides access to create a collection using your Rice Google Drive account as an endpoint allowing you to transfer data between your Rice Google Drive account and other Globus endpoints.

How to Access your Google Drive with Globus

The nodes provide massively parallel file transfers to facilitate moving large data sets efficiently. You will be able to move data between participating institutions available via Globus including between DTN

...

, DTN2, DTN HA. Additionally, if you install and configure the Globus Connect software you will be able to transfer files using your local computer as an Endpoint.

Prerequisite for Using This System

You must have a cluster account.

...

You must read the relevant quick start guides on https://docs.globus.org/

Using Globus to transfer files

You will utilize the Endpoints named: rice#dtn for "/work", "/dascratch", and "/gpfs-biou", rice#dtn2 for "/bgqscratch" and "poscratch".

Your Path destination or source will be in either the "/work" shared filesystem available only on DAVinCI and Blue Biou or "scratch" shared filesystems available on DAVinCI, Blue Gene/Q, Blue Biou, and PowerOmics. Minimally to receive or send data you will need to pick a subdirectory with which you have read and write access. For "/work" this will be a subdirectory you create under your sponsor's netID directory within "/work". When using the respective "scratch" directory use a subdirectory you have created. Use "/" for your Path to see all of the filesystems currently available.

Tip

The DTN/DTN2 nodes have 10Gb/s network connections with jumbo frames enabled. DTN HA has a 40Gb/s network connection with jumbo frames enabled. A transfer to similarly configured Internet2 Endpoints will take advantage of these capabilities.
