Your customer wants an Intel® Cluster Ready certified cluster larger than any cluster you have built before? Don’t worry! The largest cluster that has been Intel Cluster Ready certified, up to now that is, has 1688 nodes1.
There are several ways to certify a large cluster. The direct way is to run Intel® Cluster Checker in certification mode on the entire cluster. In some cases it is faster to run certification across smaller sub-clusters.
For a vendor who already builds and certifies smaller clusters, it’s easy. A larger cluster can be divided up into smaller sub-clusters of, say, 16-64 nodes. Intel Cluster Checker can then be run in certification mode on each of those sub-clusters.
Once all sub-clusters have individually passed the certification run, and the output data is saved, create a new sub-cluster from a few nodes from each of the sub-clusters. Perform a certification run over this sub-cluster. Finally, submit the output from all Intel Cluster Checker runs to the Intel Cluster Ready team for certification to complete the process.

Increase HPC server density using half-width Intel® Server Board S2600JF motherboards
The Intel® Server Board S2600JF family consists of high-density, half-width server boards optimized for HPC application performance. Each server board supports two Intel® Xeon® E5 family processors, eight memory sockets supporting LR/U/R-DIMMs for maximum memory bandwidth up to 1600MHz and QDR/FDR Infiniband options.
The Intel Server Board S2600JF makes use of several key new Intel® Server Board Technology Innovations:
- The Intel® Advanced Management Technology helps simplify and optimize system management for higher capacity and more secure platform management.
- Intel® Quiet Thermal Technology enhancements, including Advanced Thermal Sensor Array and Thermal Trip Shutdown, provide thermal and acoustic management to reduce unnecessary noise and provide cooling flexibility while maximizing system efficiency.
- This board also makes use of power delivery enhancements from the Intel® Efficient Power Technology to help improve power efficiency and reliability.
What this all means is that you can now have double the computing capacity in the same space as traditional full-width boards -- four servers instead of two in a 2U space. With Intel Xeon E5-2600 processors, this works out to be eight total sockets and 64 cores available per 2U chassis. The previous density was 4-sockets and 32-cores per 2U chassis.
Increased power efficiency can be expected as each set of two half-width boards uses a single power supply. There is reduced heat as there is one less power supply generating heat, including fewer voltage regulators and a more efficient chassis design that minimizes interior thermal hot spots. A single efficient backplane for I/O Backplane has nine 3.5" drives or twelve 2.5" drives. This allows for RAID models including RAID 5+0 with support for up to four drives. Each board supports one 16x PCIe 2.x plus one x8 onboard IO connection for FDR Infiniband, 10GbE, SaS or others.
