1. A method of determining scheduling priorities of jobs, each job comprising one or more programs, of different types to facilitate workload management of job execution in a clustered processing environment by enabling management of different types of computing resources separately in the clustered processing environment comprising different types of computing resources, the method comprising: allocating, by one or more processors of the clustered processing environment, shares of multiple managed resource types of a plurality of managed resource types to at least one user entity of a clustered processing environment, wherein the allocating comprises allocating one or more shares of each of the multiple managed resource types to the at least one user entity, wherein the multiple managed resource types are different types of computing resources of one or more computing machines in the clustered processing environment, and wherein resources of the clustered processing environment are shared to perform system tasks; and assigning, by a job scheduler executing on the one or more processors of the clustered processing environment and responsible for scheduling jobs using the multiple managed resource types, a job priority for a subsequent job submitted by a user entity of the at least one user entity, wherein the job priority is determined based on a type attribute of the subsequent job, the type attribute identifying a resource type of the only managed resources types of the different types of computing resources capable of completing the subsequent job and wherein the job priority of the subsequent job is also determined based on a number of the user entity's remaining shares of each individual managed resource type of at least two managed resource types allocated to the user entity, wherein a first managed resource type of the two managed resource types is the resource type identified by the type attribute, wherein the first managed resource type has a greater influence in determining the job priority of the subsequent job than other managed resource types excluding the first resource type comprising the at least two managed resource types; and executing, by at least one resource of the resources of the clustered processing environment identified by the type attribute, the subsequent job, at a given time, the given time determined by the one or more processors based on the assigned job priority.
