Error when sourcing or using compilervars.csh/ippvars.csh - arch: Undefined variable
If you have the error when sourcing or using compilervars.csh/ippvars.csh. The errors are as followed:
According to the website, Error when using compilervars.csh/ippvars.csh - arch: Undefined variable. from Intel
Problem Description:
A defect exists in the Intel® Integrated Performance Primitives (IPP) 8.1 Initial release in the ippvars.csh file distributed for Linux* (found under: /opt/intel/composer_xe_2013_sp1/ipp).
The IPP 8.1 release (Package ID: l_ipp_8.1.0.144) is available as a stand-alone download or bundled with the Intel® Composer XE 2013 SP1 Update 2 release (Package id: l_ccompxe_2013_sp1.2.144) for customers with valid licenses from the Intel Registration Center.
The defect is caused by improper initialization an internal variable used within the script that leads to the error “arch: Undefined variable.” when the script is sourced directly or indirectly via the compilersvars.csh script (found under: /opt/intel/composer_xe_2013_sp1/bin).
Resolution:
This defect is fixed in the Intel® C++ Composer XE 2013 SP1 Update 3 Release (Package id: l_ccompxe_2013.1.3.174 - Version 14.0.3.174 Build 20140422) now available from our Intel Registration Center.
In lieu of a permanent fix, users (or sys-admins) with appropriate root privileges can edit the ippvars.csh file to insert ONLY the new line 37 as noted in the code snippet below (ahead of line 38 which is the original line 37) to set the variable arch to the value of the first incoming argument (e.g. $1):
$ cd /opt/intel/composer_xe_2013_sp1.2.144/bin $ source ./compilervars.csh intel64 arch: Undefined variable.

Singaren - Launch of SLIX, the Singapore and the region's first 100Gbps High Speed R&E Network, 28 Aug 2014
SINGAPORE,
28 August 2014 – Singapore Advanced Research and Education Network (SingAREN)
announced today the launch of SingAREN-Lightwave Internet Exchange (SLIX),
the first 100Gbps community network to be set up in the Southeast Asia region.
With
SLIX, Singapore’s Research and Education (R&E) community will gain seamless
access to a super high speed network with a hundred times more capacity than
before; and enjoy bandwidth fully dedicated to their use. Built on an optical
fibre core comprising dark fibres, SLIX allows resiliency, future capacity
upgrade, and technology-proof network connectivity.
The
new network also opens up new possibilities as a test-bed, extending database
mirroring services, bilateral disaster recovery, high performance computing
federation and shared services, high volume peering for content data networks
and other value-adding services to the R&E community. In addition, SLIX
will also enable research organisations to test different protocols for
interconnections such as the Infiniband; and optical network researchers to
carry out their experiments.
“SingAREN
is proud to be the first to launch a 100 Gbps research and education network in
the region. By increasing the network speed by ten-fold and with our suite of
value-added services, SingAREN aims to facilitate collaborations amongst our
local research organisations and with their international counterparts,” said
A/Prof Francis Lee Bu Sung, President of SingAREN. “We would like to thank
A*STAR, NTU and NUS for working closely with us to realise this network.”
Funded
by SingAREN and the National Research Foundation (NRF), SLIX is a collaboration
and a network built between SingAREN, the Agency for Science, Technology and
Research (A*STAR), the Nanyang Technological University (NTU) and the National
University of Singapore (NUS).
SingAREN
selected 3D Networks to build the first 100 Gbps research and education network
in the region. 3D Networks has deployed a flexible and programmable Packet
Optical Platform meeting the advanced requirements of global research
collaborators, and capable of scaling up to 400Gbps and beyond. 3D Networks
built the DWDM network with the Ciena (NYSE: CIEN)
6500 Converged Packet Optical solution, and
with Ciena’s Network Operations Centre and Network Transformation Solutions
team providing management and monitoring of the network. The solution is
supplemented with Brocade’s Open Flow enabled equipment.
Bluetel
Networks is the fibre cable provider for SLIX.
