Built a 4 board cluster today

Trying to get MPI built, but some errors compiling, working on that

Just got an 8 board cluster up and had troubles with MPI but figured them out. Let me know if you need help!

capnrob97,
Can you open a separate thread on your n-body stuff. Fascinating work. Saw some of your videos:-)

Will do, working now on adding graphics to the US Army MPI nbody code from the link you provided earlier in this thread.

Today this arrived at my ECMNET server:
Code: Select all
[2016-11-11 14:27:40 GMT] GW_4_505: prime factor returned by paul@leyland.vispa.com (par3_2)!  Factor=193947590303151513210178748272702655079708377  Method=ECM  B1=43000000  Sigma=3


It's the first non-trivial (meaning more than 30 digits) factor found by my 4-board cluster. The code runs entirely on the ARM cores.

For the uninitiated, ECM is the Elliptic Curve Method of integer factorization and GW_4_505 is shorthand for the 244-digit composite factor of 505 * 4^505 - 1. The remaining cofactor is still composite and has 199 digits. The factor was found on the second core of the third machine in the cluster, as indicated by "par3_2".

If anyone here would like to join in, the ECMNET server is publicly visible at 109.109.168.71:8094 and I'll be more than willing to help you get started.
