It looks as if there is something unstable with the 2800-post main linear algebra thread, so let's start a fresh new one

This isn't too awful as large matrices go: density 138, and

Code:

matrix is 32749672 x 32749897 (16829.3 MB) with weight 4405314772 (134.51/col)
sparse part has weight 4084193513 (124.71/col)
using block size 8192 and superblock size 1351680 for processor cache size 14080 kB
commencing Lanczos iteration (10 threads)
memory use: 14743.3 MB

linear algebra completed 87999 of 32749897 dimensions (0.3%, ETA 563h45m)

So ETA is about the first week in July
