LINPACK Benchmark

[Mukarram]

Hey everyone!

I'll be very brief in my question - how do I set up and use the LINPACK benchmark (that calculates your cluster's speed in FLOPS) on my PelicanHPC cluster?

Thanks!

Mukarram.

Hi,
Just cd to /home/user/hpl and read the README_PELICAN file, which has the instructions.
Cheers, M.

Just a quick question.
Where is the output file that is created when running the xhpl executable? If there is one.

Hey,

I don't think an output file is created (there might be), but you can generate one by adding " > outputfile.txt" to the end of your command for executing xhpl. So, it would be something like

orterun --hostfile /home/user/tmp/bhosts -np 10 xhpl > outputfile.txt

This would create an output file in the same directory as xhpl resides, with the name outputfile.txt

Hi Michael

i want to get started to benchmark my  cluster using HPL on the pelicanHPC, i have tried to read ur previous posts, and when i try to access the README_PELICAN file for instructions, it cannot open on my frontend, trying to open the file shows me a calendar, and when i go to the command prompt, and try to change directory, it tells me no such file exists. i wonder what the problem is, i need to get started with the process but am stuck at this point. request for your assistance.

I just started up a frontend (v2.6) using Virtualbox, and the file opened up fine. If you are using permanent storage and you have not copied the example files over, perhaps you have modified or deleted the file? The released image has the file, and it can be viewed/edited properly.
