The storedsum calculations for X=2x10^20 had been divided into 2500 tasks, of which around 2350 are complete.<br />
While those for X=9x10^21 had been divided into 20000 tasks, and about 12000 of those are complete.<br />
<br />
Once all the outputs are in place, the next step will be to just add all the output matrices (this step is almost instantaneous even on a normal laptop), and create the final storedsum matrices to be used in subsequent computations. These should hopefully start in a few days.<br />
<br />
The progress has been far faster than expected, which can be attributed to the enthusiastic participation observed (<a href="http://anthgrid.com/dbnupperbound/top_users.php" rel="nofollow">Top users</a>

. <a href="http://anthgrid.com/dbnupperbound/show_user.php?userid=40" rel="nofollow">Bryan</a> here deserves a special mention for the kind of computational capacity he has brought in.<br />
