Constructor Detail

CachePartitioner

public CachePartitioner(SIRStream str,
                        WorkEstimate work,
                        int numTiles,
                        int code_cache_size,
                        int data_cache_size)

Method Detail

getCodeCacheSize

public static int getCodeCacheSize()

getDataCacheSize

public static int getDataCacheSize()

doit

public static SIRStream doit(SIRStream str,
                             int code_cache,
                             int data_cache)

Toplevel call.

toplevel

public SIRStream toplevel()

This is the toplevel call for doing partitioning. Returns the partitioned stream.

calcPartitions

public SIRStream calcPartitions(Map<SIROperator,Integer> partitionMap)

The toplevel call for calculating partitions without fusing anything in the stream. Note that the stream might be re-arranged if the partitioner couldn't undo the canonicalization that it used; that's why a new stream is returned. The hashmap that is passed in is cleared and filled with a mapping from SIROperator to String denoting list of partition numbers that a given SIROperator is assigned to.

getConfig

public at.dms.kjc.sir.lowering.partition.cache.CConfig getConfig(SIRStream str)
