If Red Hat executives in downtown Raleigh have smiles on their faces this evening, IBM just may have helped create the happy mood.

Big Blue is providing an energy boost for Red Hat (NYSE: RHT) by picking its Enterprise Linux to run Blue Gene supercomputers and new servers.

The Hatters are scheduled to disclose their latest earnings Thursday after the markets close. But just last week IBM announced it had selected Red Hat Enterprise Linux for its IBM Power servers used in Blue Gene supercomputers and also for its Power 775 server line.

In the posting about its Linux choice, IBM (NYSE: IBM) told potential buyers the move enables the “Exploitation of the latest hardware innovation” while offering “a broad range of the latest open source software components,” along with “increased flexibility and greater scalability.”

How is that language for a Christmas present, eh?

Plus, the U.K. Register notes, IBM is going with Linux over a technology it recently acquired.

“Big Blue is going to Red Hat for a Linux environment for its largest supercomputers, and it is mothballing its own LoadLeveler workload manager for x86 clusters in favor of the Platform LSF control freak that it acquired a little more than a year ago,” wrote Timothy Prickett Morgan.

The announcement was part of an ongoing IBM-Red Hat partnership.

“IBM and Red Hat are collaborating to provide you with a new multi-year pricing structure for Red Hat Enterprise Linux (RHEL) for IBM POWER7® IH (9125-F2C) and IBM BlueGene/Q (0207-200) servers,” Big Blue explained,” IBM explained.

“The BlueGene/Q system is the third generation of massively parallel supercomputers in the IBM System Blue Gene® Solution series. This server offers scalable HPC power optimized for running highly parallel computation. The IBM POWER7 IH, a supercomputer, offers a massive scale-out high performance computing server that has been optimized for running large, parallel science workloads and algorithms.”

Morgan got into the weeds with his description of how IBM and Red Hat tuned up RHEL for high-performance computing.

“IBM and Red Hat got together and tuned up RHEL 6 for the 18-core PowerPC A2 in the BlueGene/Q and the four chip, 32 core Power7 multichip module used in the Power 775 server nodes, exploiting not only their processors and memory but also the proprietary interconnects that these machines both employ to scale out to 100 petaflops in the case of BlueGene/Q and several tens of petaflops with the Power 775s.”

In other words, RHEL is going to be involved in major-league data crunching. And as the world’s businesses and governments rush to embrace “big data” for coordination and analysis, Red Hat could be at the forefront.

IBM’s endorsement of the latest Enterprise Linux has to help the Hatters’ credibility when it comes to making sales. RHEL already is used by many Wall Street and financial firms worldwide. Its “cloud computing” platforms continue to grow, and now comes supercomputing power capability.

Of course, IBM and Red Hat are long-time partners. There’s been talk at times that Big Blue could gobble up the world’s top Linux firm.

But IBM endorsement means something to Red Hat shareholders even without a buyout offer.

IBM’s tout of the Hatters in the RHEL choice continued:

“RHEL is a Linux-based operating system designed for enterprise environments.

“RHEL exploits the latest IBM POWER7 and virtualization technologies to help maximize system resources and provides exceptional qualities of service.

“RHEL includes a broad range of popular open source software components that are easy to install and run on IBM POWER7 servers.”
