hi all,
We have implemented Spill-Receive L2 cache (- its a Paper) . And its working
successfully. The ouput is obtained in stats.txt.
But we want the statistics in terms of throughput, speedup and performance.
Which is not in stats.txt
Can u help us in dis regard
Th code written in cacheset.cc in cahe part is
void
CacheSet::moveToHead(CacheBlk *blk,int n)
{
int t_pos,j,k,i = 0,num_blks;
int flag=-1;
num_blks=assoc/n; //number of blks in a set per cpu
if(assoc==8)
{
if(blk->contextSrc==-1)
i=0;
else
i=blk->contextSrc;
if (blks[i*num_blks] == blk)
return;
}
if (blks[0] == blk)
return;
// write 'next' block into blks[i], moving up from MRU toward LRU
// until we overwrite the block we moved to head.
CacheBlk *tmp,*next = blk;
// finding the position of the block , if already present in the set
for(j=0;j<assoc;j++)
{
if(blks[j]==blk)
{
flag=j;
break;
}
}
//finding to which cpu the block to be moved belongs to
for(k=0;k<n;k++)
if(j>=num_blks*k && j<num_blks*k+num_blks)
break; // the block to be inserted belongs to kth
cpu
if(assoc==8 && blk->contextSrc == -1) // inserting to MRU of the kth
cpu
{
i=k*num_blks;
t_pos=num_blks*i+num_blks;
do {
assert(i < t_pos);
// swap blks[i] and next
tmp = blks[i];
blks[i] = next;
next = tmp;
++i;
} while (next != blk);
return;
}
if(assoc==4) // assuming that the block to be inserted into L1 cache
{
i=0;
do {
assert(i < assoc);
// swap blks[i] and next
tmp = blks[i];
blks[i] = next;
next = tmp;
++i;
} while (next != blk);
return;
}
if(assoc==8)
{
i=blk->contextSrc*num_blks;
t_pos=i+num_blks;
if(flag!=-1)
{
//if the position of the block to be inserted is lesser than the
existing blocks position
if(i<j)
{
//if the block and the position to be inserted
is of the same cpu
if (j>i&& j<t_pos)
{
do {
assert(i < j+1);
// swap blks[i] and next
tmp = blks[i];
blks[i] = next;
next = tmp;
++i;
} while (next != blk);
}
else
{
while(i<t_pos)
{
// swap blks[i] and next
tmp = blks[i];
blks[i] = next;
next = tmp;
++i;
}
blks[j]=tmp;
}
}
else if(i>j)
{
while(i<t_pos)
{
// swap blks[i] and next
tmp = blks[i];
blks[i] = next;
next = tmp;
++i;
}
//finding to which cpu the block to be moved
belongs to
for(k=0;k<n;k++)
if(j>=num_blks*k && j<=num_blks*k+num_blks)
break;
//belongs to kth cpu
if(j<num_blks*k+1)
while(j<num_blks*k+1) //storing
the replaced block in LRU of kth cpu
{
blks[j]=blks[j+1];
j++;
}
blks[j]=tmp;
}
}
}
