US Patent:

40691489, Jan 17, 1978

Filed:

May 27, 1971

Appl. No.:

5/147398

Inventors:

David Glenn Hutton - Newark DE
Francis Leonard Robertaccio - Hockessin DE

Assignee:

E. I. Du Pont de Nemours and Company - Wilmington DE

International Classification:

C02C 106
C02C 510

US Classification:

210 11

Abstract:

Industrial waste water, containing impurities which poison or otherwise inhibit bacterial forms employed in biological treatment of waste water, is purified by a process which comprises subjecting the waste water to a biological treatment process in the presence of activated carbon or fuller's earth. A gas containing molecular oxygen is distributed within the liquid mixture during treatment to provide oxidation means. Despite the presence of the poisonous or inhibiting impurities, the process efficiently reduces the biochemical oxygen demand, chemical oxygen demand and total organic content of the waste water in an unusually rapid manner, and removes material not normally removed by the biological treatment alone.

International Classification:

G06F 9/38
G06F 9/50

Abstract:

Embodiments include load-balancing a plurality of simultaneous threads of a processor. An example method includes computing a minimum group count for a thread from the plurality of threads. The minimum group count indicates a minimum number of groups of instructions to be assigned to the thread. The method further includes computing a maximum allowed group count for the thread. The maximum allowed group count indicates a maximum number of groups of instructions to be assigned to the thread. The method further includes issuing one or more groups of instructions for execution by the thread based on the minimum group count and the maximum allowed group count for the thread.
