The Advanced Techonology Lab, a.k.a. the @lab, is focused on bringing new computing infrastructure to campus and making that infrastructure easily accessible to all members of the UAB community. In that spirit, our current efforts involve Grid Computing and the middleware that makes collaborations possible between groups on campus and around the globe.

The Advanced Technology Lab is a resource of High Performance Computing Services, located in Lister Hill Library and part of the Office of the Vice President for Information Technology

DAKOTA Slides

Here are some slides listing the capabilities and features of DAKOTA,

DAKOTA Introduction 1

With a Black-Box Interface, DAKOTA does not require access to the source code of an external application. It provides an interface by exchanging data from text files.

DAKOTA Introduction 2

DAKOTA contains many other features than those listed in the above slide, many new algorithms are added with each new version. e.g., addition of JEGA Algorithm which contains Multi-objective Genetic Algorithm (MOGA) and Single Objective Genetic Algorithm (SOGA) in version 3.3.

Hi All,

The migration from CVS to subversion can be done by using the cvs2svn tool.
More documentation about this tool can be obtained here.

VMware Server e.x.p. MUI notes

[phpwiki]
After installing the new free VMware Server product I couldn't get the
vmware-mui-distrib tarball to install. It kept aborting with the message
"Failure" after saying it detected an previous install of vmware. Duh!, I
had put it there.

The previous install wasn't actually the problem though. I found the
[limited instrux for the new release|http://www.vmware.com/support/server/doc/releasenotes_server_beta.html#install]
and the said make sure libdb.so.3 is installed, which comes in the
compat-db rpm, btw. I installed it, still no luck.

Looking at the perl code it seemed to be looking for a previous install of

Certs needed to install MyProxy G4

| | | | | | | |

Need a server cert that has no password. Commands are:

(1) change directory into the grid-security directory: cd /etc/grid-security

(2) Generate the server key (with password): openssl genrsa -des3 -out server.key 1024

(3) Generate certificate *without a password*: openssl rsa -in server.key -out server.pem

(4) Create CSR (Certificate Signing Request) to affirm that the server key is valid. The server.pem is used in place of server.key as we don’t require a password:
openssl req -new -key server.pem -out server.csr

The information you are about to be asked to enter information will be incorporated into your certificate request as the Distinguished Name or a DN of the signed cert. [ If you enter ‘.’, the field will be left blank ]
