+# Cloud_Computing_PA1
+Benchmark different parts of computer system using Chameleon testbed (CS553)
+
+Run CPU Benchmark
+Directory ‘PA1_VICHARE_’ has all the benchmarking programs. Files
+‘cpu_benchmark.c’ and ‘cpu_benchmark_2.c’ performs CPU benchmark.
+‘cpu_benchmark.c’ - This program calculates latency, GFLOPS and GIOPS of CPU
+at varying concurrency level for 1, 2, 4 and 8 threads.
+
+It takes few command line arguments which are mentioned below:
+-i calculate IOPS
+-f calculate FLOPS
+-o O Number of operations
+-t T Number of threads
+
+To run this program individually do below mentioned steps:
+gcc -mavx2 cpu_benchmark.c -o cpu -lpthread
+./cpu -f|-i -o O -t T
+
+To run the CPU benchmark to calculate GIOPS for 1000 operations on 2 threads,
+use following command:
+./cpu -i -o 1000 -t 2
+
+To run this program for all possible combinations of GIOPS/GFLOPS, number of
+operations and threads, run following command
+make cpu
+
+‘cpu_benchmark_2.c’ - This program runs the benchmark on double precision
+floating point and integer instructions and 8 threads for a 10-minute period for
+each one, and take samples every second.
+
+It takes following command line arguments :
+-i calculate IOPS
+-f calculate FLOPS
+
+To run this program individually, run following commands:
+gcc -mavx2 cpu_benchmark_2.c -o cpu2 -lpthread
+./cpu2 -f // to calculate FLOPS
+./cpu2 -i // to calculate IOPS
+
+To run this program for all possible combinations of IOPS/FLOPS, run following
+command:
+make cpu2
+
+Run Memory Benchmark
+File ‘memory_benchmark.c’ performs Memory benchmark.
+‘memory_benchmark.c’ - This program calculates latency(in microseconds),
+memory throughput(in MB/sec) for read/write, sequential write and random write
+operations for 8B, 8KB, 8MB and 80MB block sizes at varying concurrency level
+for 1, 2, 4 and 8 threads.
+
+It takes following command line arguments:
+-w Read/write operations
+-s Sequential write operations
+-r Random write operations
+-o O Number of operations
+-t T Number of threads
+-b B Block size
+
+To run this program individually do below mentioned steps:
+gcc memory_benchmark.c -o memory -lpthread
+./memory -w|-s|-r -o O -b B -t T
+
+To run the Memory benchmark to calculate throughput and latency for read/write
+operations for 1000 operations on 2 threads having block size 8B, use following
+command:
+./memory -w -o 1000 -t 2 -b 8
+
+To run this program for all possible combinations of type of operations, number of
+operations, threads and block sizes, run following command
+make memory
+
+Run Disk Benchmark
+File ‘disk_benchmark.c’ performs Disk benchmark.
+‘disk_benchmark.c’ - This program calculates latency(in milliseconds), memory
+throughput(in MB/sec) for read/write, sequential read and random read
+operations for 8B, 8KB, 8MB and 80MB block sizes at varying concurrancy level
+for 1, 2, 4 and 8 threads.
+
+It takes following command line arguments:
+-w Read/write operations
+-s Sequential read operations
+-r Random read operations
+-o O Number of operations
+-t T Number of threads
+-b B Block size
+
+To run this program individually, run following commands:
+gcc disk_benchmark.c -o disk -lpthread
+./disk -w|-s|-r -o O -b B -t T
+
+To run the disk benchmark to calculate throughput and latency for read/write
+operations for 1000 operations on 2 threads having block size 8B, use following
+command:
+./disk -w -o 1000 -t 2 -b 8
+
+To run this program for all possible combinations of type of operations, number of
+operations, threads and block sizes, run following command
+make disk
+
+Run Network Benchmark
+File server.c performs the benchmark for the server side of network benchmark.
+File client.c performs the benchmark for the client side of network benchmark.
+Parameter space includes the TCP protocol stack, UDP, fixed packet/buffer size
+(64KB), and varying the concurrency (1 thread, 2 threads, 4 threads, 8 threads);
+and also multi-threaded support exists at both client and server.
+
+It takes the following command line arguments:
+- Connection type : TCP/UDP
+- Block Size: 64Kb fixed
+- No. of Threads: 1,2,4,8
+
+Run GPU Benchmark
+‘CUDA.cu’ file performs GPU benchmark. Follow below mentioned command to
+run GPU code:
+nvcc CUDA.cu -o gpu_benchmark
+./gpu_benchamrk
+
+To run the CPU, Memory and Disk benchmarks one by one , run
+following commands:
+make all
