  =3D Long-term Issues =3D
  We have a plan to redesign Hama to be based on BSP model and be specified=
 to shared nothing systems consisting of several thousands commodity server=
s, which is generally called cloud computing environments.

  =3D=3D=3D Design Considerations =3D=3D=3D
-  * Fault Tolerance
+  * Fault Tolerance - Hama aims at running on a several thousands of commo=
dity servers, so it is subject to some fault. In addition, Hama is for larg=
e-scale processing that generally takes long time ranging from few minutes =
to several hours. Therefore, it is important for Hama to finish some given =
jobs although faults occur during processing. If not, Hama has to restart a=
ll jobs.
-  * Heterogeneity

   * Efficiency
   * Easy to Use

  =3D=3D=3D TODO =3D=3D=3D
   * A survey on matrix and graph processing algorithms based on BSP progra=
mming model.
-  * Developing a fault-tolerant mechanism for BSP model and Shared-nothing=
 architecture and heterogeneous.
+  * Developing a fault-tolerant mechanism for BSP model.
+  * Developing a struggling mechanism for BSP model.
+  * Implement BSP frameworks based on the source code that we have done.
-  * A selection of the basic primitive operations for matrix processing an=
d linear algebra.
+  * A selection of the primitive operations for matrix processing and line=
ar algebra.
+  * Implement the primitive operations for matrix and linear algebra.
-  * Design operation models based on the basic primitive operations develo=
ped above.
+  * Develop operation models based on the primitive operations developed a=
bove.
+  * Implement processing framework for matrix and linear algebra.
   * Design domain-specific language that well reflects to algebraic charac=
teristics.
