Utilize M10k Memory block

Hi, I have compiled my kernel and i know only uses 16% of the M10k memory. Is there way i can use more of it? Also, i view my report, it says "loop sacrificed fmax to achieve II to 1." Bu...

No idea why, but my kernel freezes indefinitely during execution.

input/output declared as shared buffer between host/fpga.

input -> kernel1 -> channel -> kernel 2 -> output. 

data_input = clCreateBuffer(context, CL_MEM_ALLOC_HOST_PTR, buffer_size, NULL, &status);
           data_output = clCreateBuffer(context, CL_MEM_ALLOC_HOST_PTR, buffer_size, NULL, &status);
            b = (float *) clEnqueueMapBuffer(queue_kernel1,data_input,CL_TRUE,CL_MAP_READ,0,size*sizeof(float),0,NULL,NULL,&status);   
            // put data in b 
            clEnqueueTask (kernel 1)
            clEnqueueTask (kernel 2)
            // take data out
            out = (float *)clEnqueueMapBuffer(queue_kernel2,data_output,CL_TRUE,CL_MAP_READ,0,size*sizeof(float),0,NULL,NULL,&status);        
            



__kernel1(input){
//load input store in buffer 
//send to channel
writeintelchannel(something_ch,buffer);
}
__kernel2(output){
//load data from channel
//some add/mul
output = out;
}
