....that do not oscillate between successive loop iterations after convergence Resource allocation: Does Hippodrome allocate a reasonable set of resources for a given workload 5.3. 1 Workloads Our evaluation is based on a variety of synthetic workloads and a expanded version of the PostMark [Kat97] benchmark described below. The synthetic workloads are useful for validating whether the Hippodrome loop performs correctly, because we can determine the expected behavior of the system. The PostMark benchmark is useful because it lets us investigate how Hippodrome performs under a slightly more ....
....number of outstanding requests and the duration of on off periods. We used the Poisson arrival process for each stream in the synthetic workloads and limited the number of requests outstanding from a stream at a given time to a maximum of four requests. We also used the PostMark benchmark [Kat97] which simulates an email system. The benchmark consists of a series of transactions, each of which performs a file deletion or creation, together with a read or write. Operations and files are randomly chosen. Using the default parameters, the benchmark fits entirely in the array cache, and ....

....insignificant when the application is compute bound. As application processing time per block diminishes (from left to right in Figure 5) reducing I O overhead yields progressively higher returns because the I O overhead is a progressively larger share of total CPU time. 7. 3 PostMark PostMark [22] is a synthetic benchmark aimed at measuring file system performance over a workload composed of many short lived, relatively small files. Such a workload is typical of mail and netnews servers used by Internet Service Providers. PostMark workloads are characterized by a mix of metadata intensive ....

....is actually useful. To test the assumption that there is some benefit to handling small, short lived files differently from other files, we have devised an experiment where we can perfectly predict which files will be small and short lived. We modified Postmark, a mail oriented benchmark [7], to differentiate between lock files, small mail composer files, and mailboxes. Mailboxes are always treated as ordinary files, but our modified benchmark allows us to treat the lock files and com poser files differently. In this section, we discuss how the benchmark was modified and provide a ....

....slightly better in the unpack and configure stages because it maintains no consistency guarantees, however it loses in the build phase due to S4 s segment sized reads. Postmark was designed to measure the performance of a file system used for electronic mail, 21 netnews, and web based services [21]. It creates a large number of small randomly sized files (between 512 B and 9 KB) and performs a specified number of transactions on them. Each transaction consists of two sub transactions, with one being a create or delete and the other being a read or append. The default configuration used for ....

....request sizes in intervals of 2KB over the range [2KB, 130KB] Therefore, a mixed large workload has some sequential and local accesses and is composed of 128KB requests. All workloads are made up of 1,000 I O requests, of which 67 are reads. We also present results for the PostMark benchmark [ 14]. PostMark was designed to measure the performance of a file system used for electronic mail, news, and webbased services. It creates a large number of small files, on which a specified number of transactions are performed. Each transaction consists of two sub transactions, with one being a create ....

Two application benchmarks are used to verify that the traxtent modifications do not penalize small file workloads. Postmark [21] simulates the small file activity of busy Internet servers. Our experiments use Postmark v 1.11 and its default parameters: 5 10KB files and 1:1 read to write and create to delete ratios.
