System Changes after Storage upgrades
After a one-week shutdown in mid-December, a few alterations have been made to our systems. Click here for details.

Sample code for a Combined MPI/OpenMP two-layered "Master-Slave" Model
The nodes of computer clusters such as our Victoria-Falls cluster are often multi-core and each core may support multiple threads. This suggests a two-layer approach when programming new codes or adapting existing ones. To optimally exploit the distributed-memory structure of the cluster while at the same time keeping each shared-memory node busy, a combined MPI-OpenMP programming approach may be taken.

MATLAB Distributed Computing Server Available
HPCVL has acquired Matlab Distributed-Computing Server licenses that allow Matlab users to submit parallel Matlab jobs to our clusters. For details, see our Matlab FAQ.

Job Submission to Victoria Falls Cluster and M9000 Servers
To submit jobs to the Victoria Falls Cluster or to the Sun Enterprise M9000 Servers, a few additional lines in your Grid Engine submission script are necessary. Please check out the details here.

Default Execution Limits
HPCVL has increased the Execution Limits on our clusters to reflect the expansion of our capacity. Please check here for details.

HPCVL Fluent Licenses
The HPCVL Fluent license agreement covers 50 program runs plus 400 parallel processes, which is almost twice the previous count. Please check out the details here.

Secure Grid Portal and Access
HPCVL is requiring that all new users access central site resources through the HPCVL Secure Portal. Current users are encouraged to move to these resources as soon as possible. In time, we will be disabling ssh logins for general users. Note that while remote workup systems are currently only available via ssh, they will also be moved to Portal only access in the coming months.
Information on the HPCVL Secure Portal and how to obtain a digital certificate (required) may be obtained here.

Configuring Your Environment
Logins on the compute grid can take advantage of a default rich environment. Access to new packages and customizations can be added with just a single command. Please read more here.

Important Reminder
Please remember that all production jobs that are run on the cluster must be submitted via Grid Engine. Test jobs and compilations et al may still be run outside of Grid Engine on the Login nodes. Adherence to this policy helps ensure system stablility and efficiency.Please read this notice for details.

HPCVL Working Template v5.3
The current version of the HPCVL Working Template (HWT) is v5.3. The HWT provides an advanced toolkit for the parallelization of code, including Version Maintainance, Automatic Relative Debugging, and Simple Timing. The software may be accessed directly on our Sunfire cluster at /opt/hwt, which also contains an application example. The User's Manual can be downloaded here.
