rafal.brzegowy posted a dropbox link of his new i8 compile of ccx_2.18_static_i8.exe
the pastix compile without the i8 seems to fail on problems over 500,000 even with enough core, probably due to the limit on the number represented in 4 byte integers in the programs arrary indexing to about 4GB. The Pardiso compiles I have used don’t seem to have this problem. 256 GB should be enough for about 2,000,000 nodes in Pastix if you have a page file to store the currently unused parts of the program and other data. This is based on my experience relatively simple static structural problems. If you read the papers on pastix though you will note that the amount of speedup varies with the program and data.
