Extension of experiment time

[xwt1]

   Hello team! I need to test multiple vector index performance on c6620 and this will consume a lot of time. I have made a entension request before but it seems not work?  I wonder if this can be extended? My experiment page is on https://www.cloudlab.us/status.php?uuid=b8fd98d2-fb73-11f0-bc80-e4434b2381fc.

Best regards,
