Tivoli Workload Scheduler LoadLeveler

Získajte maximum zo svojich výpočtových prostriedkov

IBM Tivoli Workload Scheduler (TWS) LoadLeveler umožňuje užívateľom spustiť viac úloh v kratšom čase

Jedná sa o systém paralelného plánovania, ktorý potrebám spracovania a priorite každej úlohy priradí dostupné prostriedky a špeciálne inštrukcie, aby zabezpečil maximálne využitie prostriedkov.

• Prináša presné riadenie prostriedkov: dokáže obmedziť používanie jednotlivých počítačov na konkrétne časy, užívateľov alebo triedy úloh alebo dokáže počítače používať len vtedy, keď nie je klávesnica a myš aktívna
• Sleduje celkové množstvo prostriedkov, ktoré používa každá sériová alebo paralelná úloha a ponúka niekoľko volieb nahlasovania pre sledovanie úloh a využitia podľa užívateľa, skupiny, konta alebo typu za konkrétne časové obdobie
• Dokáže zahrnúť rýchlosť počítača pre prispôsobenie sadzieb vnútropodnikového obchodu so službami IT a dá sa nakonfigurovať, aby vyžadoval konto pre každú úlohu kvôli podpore účtovania vnútropodnikového obchodu so službami IT pri používaní prostriedkov
• Okrem rozhrania API, ktoré umožňuje riadenie prostredníctvom užívateľom vytvorených aplikácií, ponúka aj rozhranie príkazového riadka a grafické rozhranie
• Podporuje konfigurácie vysokej dostupnosti pre zabezpečenie spoľahlivej prevádzky a automaticky monitoruje dostupné výpočtové prostriedky, aby žiadne úlohy neboli plánované pre nefunkčné počítače
• Integruje sa do AIX WLM (Workload Manager) a do IBM HPS (High Performance Switch) pre hardvér System p a obsahuje algoritmus pre systémy Blue Gene BG/L
• Hárok riešenia: Maximalizujte hospodárnosť prevádzky a odolnosť podniku

Features, advantages and benefits

Features	Advantages	Benefits
Job Scheduling	Jobs are executed based on their priority, resource requirements and special instructions and not on the sequence of submission	Administrators can specify that long-running jobs run only on off-hours, that short-running jobs be scheduled around long-running jobs or that certain users or groups get priority. In addition, the resources themselves can be tightly controlled: use of individual machines can be limited to specific times, users or job classes or TWS LoadLeveler can use machines only when the keyboard and mouse are inactive
Easily scalable	Can easily scale up to thousands of processing nodes and thousands of parallel jobs in the job queue	Industrial strength, reliable and robust product. It is a completely distributed program with extensive failover and self-repair capabilities to survive even severe system events, usually without administrator intervention
Integration with IBM High Performance Switch (HPS) for pSeries® hardware	Integration with HPS for pSeries hardware extends the available resources	Enables immediate use of the scalable bandwidth and additional multitasking capabilities
Integration with AIX® Workload Manager (WLM)	Extends the capability of TWS LoadLeveler	Provides both resource specification on job start and resource utilization controls to prevent resource overuse by errant applications
Flexibility	Offers unprecedented flexibility with a complete array of APIs allowing a high level of site-specific customization	Offers job checkpointing and suspension with optional job cancellation, hold and re-queue. Provides great flexibility in defining real-time job and resource priority control

• Easily scalable to thousands of processing nodes and thousands of parallel jobs in the job queue, TWS LoadLeveler is an industrial-strength product that has been available on parallel computing platforms for 15 years.

• TWS LoadLeveler incorporates the latest technologies in parallel batch scheduling research. An early adopter of the backfill scheduling algorithm, IBM has continued to improve the speed, scalability and performance of this algorithm in TWS LoadLeveler.

• The first batch scheduler to offer a complete scheduling API, TWS LoadLeveler currently offers unprecedented flexibility with a complete array of APIs allowing a high level of site-specific customization.

• TWS LoadLeveler is a completely distributed program with extensive failover and self-repair capabilities to survive even severe system events, usually without administrator intervention.

• TWS LoadLeveler offers job check pointing and suspension with optional job cancellation, hold and re-queue. These capabilities provide great flexibility in defining real-time job and resource priority control.

• TWS LoadLeveler integrates with AIX Workload Manager (WLM) to provide both resource specifications on job start and resource utilization controls to prevent resource overuse by errant applications.

• A new TWS LoadLeveler algorithm is available for the Blue Gene® machine BG/L that extends TWS LoadLeveler's reliable performance to unprecedented scalability levels (on the order of tens of thousands of processors) within the Blue Gene family of machines.

• TWS LoadLeveler integrates easily with the IBM High Performance Switch (HPS) for pSeries hardware, enabling immediate use of the scalable bandwidth and additional multitasking capabilities

• IBM Tivoli Workload Scheduler for distributed and integrated end-to-end enterprise workload scheduling

• IBM Tivoli Dynamic Workload Broker for dynamic matching of workloads to best available resources within mainstream enterprise and Grid scheduling networks

• IBM Tivoli Workload Scheduler for Applications for extensive IBM Tivoli Workload Scheduler integration with SAP, Oracle and PeopleSoft business applications

• IBM Tivoli Workload Scheduler for z/OS for mainframe and integrated end-to-end enterprise workload scheduling
