Hello all, I was curious as to how run many jobs serially on a Cray XE6 machine. You usually qsub things with a ccmrun (for a serial job) or an aprun (instead of mpirun or mpiexec). I first wanted to use the Pool() function, but due to it not being SMP based hardware it would be limited to 32 processors. Even an mpi4py application of something like a pool wouldn't work, because I am not giving the main program all of the processors. I would be running that script 64 times if I were to say aprun -n 64 mpipool.py, …

Hello all, I was writing code that was supposed to spawn multiple jobs from a sqlite DB and my first idea was to implement the multiprocessing Pool function. I'm not sure if this question would be better suited somewhere related to shell scripting, but I'm not sure how to call the script properly. It works fine if I'm doing Pool(3) on my local mac. The problem is the Cray machine needs you to run aprun to run in the background. So if I were to say aprun -n 64 myscript.py which was a Pool(64) it actually spawns 64 myscript.py's which …

Hey guys, I wasn't exactly sure where to put this post, but this was my best guess: I'm on a HPC and wanted to use vim as a python IDE and was trying to install my own version of vim (7.3) with a python interpreter. I use configure to enable pythoninterp but then I get a checking Python version... 2.6 checking Python is 1.4 or better... yep checking Python's install prefix... /usr checking Python's execution prefix... /usr checking Python's configuration directory... can't find it! Is this because it doesn't have the proper permissions to change something in /usr? I was …

Hi there, I am not sure if this is the correct forum for this, but I am currently working with an HPC machine for business use and it is currently running Ubuntu 11.04 (I have yet to update due to software incompatibilities). Anyways, some of the users would prefer to be working within a Windows environment and other in a Linux environment. I found that my best solution would be to dual-boot Windows and Ubuntu, but when looking further into that process, I found that it's not the easiest task as Windows likes to overwrite the Linux boot manager making …

Hi All, Ok to make it clear from the start I'm a 'noob' with anything complex in computing. Currently I have been asked to look into using the Linpack Benchmark Software to run on computer workstations for Energy Star performance testing. I have spent the last few weeks combing the internet to get information about how this code works. All the help I have found is obviously only targeted toward people who already know about running subroutines and liner equations to judge performance of computers (formally only super computers), I don't have a clue what they are talking about. My …

Less than a year after launching its high performance computing strategy, Microsoft finds its [URL= http://www.microsoft.com/hpc/] HPC Server 2008[/URL] near the top of the heap. The Windows Server 2008 derivative placed 23rd on a list of the 500 top-performing supercomputers in the world, as measured by the [URL= http://www.ncsa.uiuc.edu/] National Center for Supercomputing Applications (NCSA)[/URL]. And it’s which is still in beta; general availability is set for the end of this month. Running on a Dell PowerEdge Cluster equipped with 9,474 processor cores and 9600 GB of memory, HPC Server 2008 performed 68.5 trillion floating point operations (teraflops) per second, …

With its release on Monday of the [url=http://www.microsoft.com/hpc/en/us/default.aspx]first public beta of Windows HPC Server 2008 RC2[/url], Microsoft also was touting features introduced in the [url=http://msdn.microsoft.com/en-us/vstudio/dd582936.aspx]second beta of Visual Studio 2010[/url]. Expected in March, Redmond's next IDE will simplify development of new applications and modification of existing ones to take advantage of its high performance computing platform, according to claims. Windows Server HPC 2008 is currently scheduled for release late summer, 2010. "The topic of making serial code into parallel code continues to be very complex," said Ryan Waite, product unit manager for High Performance Computing at Microsoft in a phone …

High performance computing has long been a part of Intel’s dossier. But a deal announced on Monday with supercomputer maker Cray Inc. could paint Xeon in neon on Intel’s resume. The multi-year pact puts Intel’s dual-core Xeon processors—found in most of the world’s most powerful HPCs—in Cray’s next-generation system, called Cascade. Scheduled for availability sometime after 2010, Cascade was originally set to use Opteron chips, and still might. Intel also will help Cray develop technologies based on Intel’s QuickPath Interconnect, the high-speed, low-latency bus that replaces the front-side memory bus with two 25.6 Gbps channels per processor for accessing memory …
