eu.stratosphere.nephele.services.memorymanager.MemoryManager.computeNumberOfPages()
Computes to how many pages the given number of bytes corresponds. If the given number of bytes is not an exact multiple of a page size, the result is rounded down, such that a portion of the memory (smaller than the page size) is not included. @param numBytes The number of bytes to convert to a page count. @return The number of pages to which
